Azure OpenAI Service REST API reference

Article
09/09/2024

This article provides details on the inference REST API endpoints for Azure OpenAI.

API specs

Managing and interacting with Azure OpenAI models and resources is divided across three primary API surfaces:

Control plane
Data plane - authoring
Data plane - inference

Each API surface/specification encapsulates a different set of Azure OpenAI capabilities. Each API has its own unique set of preview and stable/generally available (GA) API releases. Preview releases currently tend to follow a monthly cadence.

API	Latest preview release	Latest GA release	Specifications	Description
Control plane	`2024-06-01-preview`	`2023-05-01`	Spec files	Azure OpenAI shares a common control plane with all other Azure AI Services. The control plane API is used for things like creating Azure OpenAI resources, model deployment, and other higher level resource management tasks. The control plane also governs what is possible to do with capabilities like Azure Resource Manager, Bicep, Terraform, and Azure CLI.
Data plane - authoring	`2024-10-01-preview`	`2024-06-01`	Spec files	The data plane authoring API controls fine-tuning, file-upload, ingestion jobs, batch and certain model level queries
Data plane - inference	`2024-10-01-preview`	`2024-06-01`	Spec files	The data plane inference API provides the inference capabilities/endpoints for features like completions, chat completions, embeddings, speech/whisper, on your data, Dall-e, assistants, etc.

Authentication

Azure OpenAI provides two methods for authentication. You can use either API Keys or Microsoft Entra ID.

API Key authentication: For this type of authentication, all API requests must include the API Key in the api-key HTTP header. The Quickstart provides guidance for how to make calls with this type of authentication.
Microsoft Entra ID authentication: You can authenticate an API call using a Microsoft Entra token. Authentication tokens are included in a request as the Authorization header. The token provided must be preceded by Bearer, for example Bearer YOUR_AUTH_TOKEN. You can read our how-to guide on authenticating with Microsoft Entra ID.

REST API versioning

The service APIs are versioned using the api-version query parameter. All versions follow the YYYY-MM-DD date structure. For example:

POST https://YOUR_RESOURCE_NAME.openai.azure.com/openai/deployments/YOUR_DEPLOYMENT_NAME/chat/completions?api-version=2024-06-01

Data plane inference

The rest of the article covers the latest GA release of the Azure OpenAI data plane inference specification, 2024-06-01.

Completions

POST https://{endpoint}/openai/deployments/{deployment-id}/completions?api-version=2024-06-01

Creates a completion for the provided prompt, parameters and chosen model.

URI Parameters

Name	In	Required	Type	Description
endpoint	path	Yes	string url	Supported Azure OpenAI endpoints (protocol and hostname, for example: `https://aoairesource.openai.azure.com`. Replace "aoairesource" with your Azure OpenAI resource name). https://{your-resource-name}.openai.azure.com
deployment-id	path	Yes	string	Deployment id of the model which was deployed.
api-version	query	Yes	string	API version

Request Header

Name	Required	Type	Description
api-key	True	string	Provide Azure OpenAI API key here

Request Body

Content-Type: application/json

Name	Type	Description	Required	Default
prompt	string or array	The prompt(s) to generate completions for, encoded as a string or array of strings. Note that <\|endoftext\|> is the document separator that the model sees during training, so if a prompt isn'tspecified the model will generate as if from the beginning of a new document. Maximum allowed size of string list is 2048.	No
max_tokens	integer	The token count of your prompt plus max_tokens can't exceed the model's context length. Most models have a context length of 2048 tokens (except for the newest models, which support 4096). Has minimum of 0.	No	16
temperature	number	What sampling temperature to use. Higher values means the model will take more risks. Try 0.9 for more creative applications, and 0 (arg max sampling) for ones with a well-defined answer. We generally recommend altering this or top_p but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.	No	1
logit_bias	object	Defaults to null. Modify the likelihood of specified tokens appearing in the completion. Accepts a json object that maps tokens (specified by their token ID in the GPT tokenizer) to an associated bias value from -100 to 100. You can use this tokenizer tool (which works for both GPT-2 and GPT-3) to convert text to token IDs. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token. As an example, you can pass {"50256":-100} to prevent the <\|endoftext\|> token from being generated.	No
user	string	A unique identifier representing your end-user, which can help monitoring and detecting abuse	No
n	integer	How many completions to generate for each prompt. Minimum of 1 and maximum of 128 allowed. Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for max_tokens and stop.	No	1
stream	boolean	Whether to stream back partial progress. If set, tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.	No	False
logprobs	integer	Include the log probabilities on the logprobs most likely tokens, as well the chosen tokens. For example, if logprobs is 5, the API will return a list of the 5 most likely tokens. The API will always return the logprob of the sampled token, so there may be up to logprobs+1 elements in the response. Minimum of 0 and maximum of 5 allowed.	No	None
suffix	string	The suffix that comes after a completion of inserted text.	No
echo	boolean	Echo back the prompt in addition to the completion	No	False
stop	string or array	Up to 4 sequences where the API will stop generating further tokens. The returned text will not contain the stop sequence.	No
completion_config	string		No
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.	No	0
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.	No	0
best_of	integer	Generates best_of completions server-side and returns the "best" (defined as the one with the highest log probability per token). Results can't be streamed. When used with n, best_of controls the number of candidate completions and n specifies how many to return - best_of must be greater than n. Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for max_tokens and stop. Has maximum value of 128.	No

URI Parameters

Name	In	Required	Type	Description
endpoint	path	Yes	string url	Supported Azure OpenAI endpoints (protocol and hostname, for example: `https://aoairesource.openai.azure.com`. Replace "aoairesource" with your Azure OpenAI resource name). https://{your-resource-name}.openai.azure.com
deployment-id	path	Yes	string	Deployment id of the model which was deployed.
api-version	query	Yes	string	API version

Request Header

Name	Required	Type	Description
api-key	True	string	Provide Azure OpenAI API key here

Request Body

Content-Type: application/json

Name	Type	Description	Required	Default
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or `top_p` but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or `temperature` but not both.	No	1
stream	boolean	If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a `data: [DONE]` message.	No	False
stop	string or array	Up to 4 sequences where the API will stop generating further tokens.	No
max_tokens	integer	The maximum number of tokens allowed for the generated answer. By default, the number of tokens the model can return will be (4096 - prompt tokens).	No	4096
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.	No	0
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a json object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.	No
user	string	A unique identifier representing your end-user, which can help Azure OpenAI to monitor and detect abuse.	No
messages	array	A list of messages comprising the conversation so far. Example Python code.	No
data_sources	array	The configuration entries for Azure OpenAI chat extensions that use them. This additional specification is only compatible with Azure OpenAI.	No
n	integer	How many chat completion choices to generate for each input message.	No	1
seed	integer	If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same `seed` and parameters should return the same result. Determinism isn'tguaranteed, and you should refer to the `system_fingerprint` response parameter to monitor changes in the backend.	No	0
logprobs	boolean	Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the `content` of `message`. This option is currently not available on the `gpt-4-vision-preview` model.	No	False
top_logprobs	integer	An integer between 0 and 5 specifying the number of most likely tokens to return at each token position, each with an associated log probability. `logprobs` must be set to `true` if this parameter is used.	No
response_format	object	An object specifying the format that the model must output. Used to enable JSON mode.	No
tools	array	A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for.	No
tool_choice	chatCompletionToolChoiceOption	Controls which (if any) function is called by the model. `none` means the model will not call a function and instead generates a message. `auto` means the model can pick between generating a message or calling a function. Specifying a particular function via `{"type": "function", "function": {"name": "my_function"}}` forces the model to call that function.	No
functions	array	Deprecated in favor of `tools`. A list of functions the model may generate JSON inputs for.	No
function_call	string or object	Deprecated in favor of `tool_choice`. Controls how the model responds to function calls. "none" means the model doesn't call a function, and responds to the end-user. "auto" means the model can pick between an end-user or calling a function. Specifying a particular function via `{"name":\ "my_function"}` forces the model to call that function. "none" is the default when no functions are present. "auto" is the default if functions are present.	No

Be sure ye get a sturdy cage, at least double the size of the bird's wingspan, with enough space to spread their wings, yarrrr!\n\n2. Perches 'n toys: Aye, parrots need perches of different sizes, shapes, 'n textures to keep their feet healthy. Also, a few toys be helpin' to keep them entertained 'n their minds stimulated, arrrh!\n\n3. Proper grub: Feed yer feathered friend a balanced diet of high-quality pellets, fruits, 'n veggies to keep 'em strong 'n healthy. Give 'em fresh water every day, or ye\u00e2\u20ac\u2122ll have a scurvy bird on yer hands!\n\n4. Cleanliness: Swab their cage deck! Clean their cage on a regular basis: fresh water 'n food daily, the floor every couple of days, 'n a thorough scrubbing ev'ry few weeks, so the bird be livin' in a tidy haven, arrhh!\n\n5. Socialize 'n train: Parrots be a sociable lot, arrr! Exercise 'n interact with 'em daily to create a bond 'n maintain their mental 'n physical health. Train 'em with positive reinforcement, treat 'em kindly, yarrr!\n\n6. Proper rest: Yer parrot be needin' \u00e2\u20ac\u2122bout 10-12 hours o' sleep each night. Cover their cage 'n let them slumber in a dim, quiet quarter for a proper night's rest, ye scallywag!\n\n7. Keep a weather eye open for illness: Birds be hidin' their ailments, arrr! Be watchful for signs of sickness, such as lethargy, loss of appetite, puffin' up, or change in droppings, and make haste to a vet if need be.\n\n8. Provide fresh air 'n avoid toxins: Parrots be sensitive to draft and pollutants. Keep yer quarters well ventilated, but no drafts, arrr! Be mindful of toxins like Teflon fumes, candles, or air fresheners.\n\nSo there ye have it, me hearty! With proper care 'n commitment, yer parrot will be squawkin' \"Yo-ho-ho\" for many years to come! Good luck, sailor, and may the wind be at yer back!"

chatCompletionsRequestCommon

Name	Type	Description	Required	Default
temperature	number	What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or `top_p` but not both.	No	1
top_p	number	An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or `temperature` but not both.	No	1
stream	boolean	If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a `data: [DONE]` message.	No	False
stop	string or array	Up to 4 sequences where the API will stop generating further tokens.	No
max_tokens	integer	The maximum number of tokens allowed for the generated answer. By default, the number of tokens the model can return will be (4096 - prompt tokens).	No	4096
presence_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.	No	0
frequency_penalty	number	Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.	No	0
logit_bias	object	Modify the likelihood of specified tokens appearing in the completion. Accepts a json object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.	No
user	string	A unique identifier representing your end-user, which can help Azure OpenAI to monitor and detect abuse.	No

messages	array	A list of messages comprising the conversation so far. Example Python code.	No
data_sources	array	The configuration entries for Azure OpenAI chat extensions that use them. This additional specification is only compatible with Azure OpenAI.	No
n	integer	How many chat completion choices to generate for each input message.	No	1
seed	integer	If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same `seed` and parameters should return the same result. Determinism isn'tguaranteed, and you should refer to the `system_fingerprint` response parameter to monitor changes in the backend.	No	0
logprobs	boolean	Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the `content` of `message`. This option is currently not available on the `gpt-4-vision-preview` model.	No	False
top_logprobs	integer	An integer between 0 and 5 specifying the number of most likely tokens to return at each token position, each with an associated log probability. `logprobs` must be set to `true` if this parameter is used.	No
response_format	object	An object specifying the format that the model must output. Used to enable JSON mode.	No
tools	array	A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for.	No
tool_choice	chatCompletionToolChoiceOption	Controls which (if any) function is called by the model. `none` means the model will not call a function and instead generates a message. `auto` means the model can pick between generating a message or calling a function. Specifying a particular function via `{"type": "function", "function": {"name": "my_function"}}` forces the model to call that function.	No
functions	array	Deprecated in favor of `tools`. A list of functions the model may generate JSON inputs for.	No
function_call	string or object	Deprecated in favor of `tool_choice`. Controls how the model responds to function calls. "none" means the model doesn't call a function, and responds to the end-user. "auto" means the model can pick between an end-user or calling a function. Specifying a particular function via `{"name":\ "my_function"}` forces the model to call that function. "none" is the default when no functions are present. "auto" is the default if functions are present.	No
