Serverless Inference

Generated on 26 Mar 2026

DigitalOcean Gradient™ AI Agentic Cloud allows access to serverless inference models. You can access models by providing an inference key.

Note: The Serverless Inference API uses a separate base URL (https://inference.do-ai.run) and is independent of the main DigitalOcean control-plane API (https://api.digitalocean.com).

Base URL https://inference.do-ai.run

OAuth Authentication

In order to interact with the DigitalOcean API, you or your application must authenticate.

The DigitalOcean API handles this through OAuth, an open standard for authorization. OAuth allows you to delegate access to your account. Scopes can be used to grant full access, read-only access, or access to a specific set of endpoints.

You can generate an OAuth token by visiting the Apps & API section of the DigitalOcean control panel for your account.

An OAuth token functions as a complete authentication request. In effect, it acts as a substitute for a username and password pair.

Because of this, it is absolutely essential that you keep your OAuth tokens secure. In fact, upon generation, the web interface will only display each token a single time in order to prevent the token from being compromised.

DigitalOcean access tokens begin with an identifiable prefix in order to distinguish them from other similar tokens.

  • dop_v1_ for personal access tokens generated in the control panel
  • doo_v1_ for tokens generated by applications using the OAuth flow
  • dor_v1_ for OAuth refresh tokens

Scopes

Scopes act like permissions assigned to an API token. These permissions determine what actions the token can perform. You can create API tokens that grant read-only access, full access, or limited access to specific endpoints by using custom scopes.

Generally, scopes are designed to match HTTP verbs and common CRUD operations (Create, Read, Update, Delete).

HTTP Verb CRUD Operation Scope
GET Read <resource>:read
POST Create <resource>:create
PUT/PATCH Update <resource>:update
DELETE Delete <resource>:delete

For example, creating a new Droplet by making a POST request to the /v2/droplets endpoint requires the droplet:create scope while listing Droplets by making a GET request to the /v2/droplets endpoint requires the droplet:read scope.

Each endpoint below specifies which scope is required to access it when using custom scopes.

How to Authenticate with OAuth

In order to make an authenticated request, include a bearer-type Authorization header containing your OAuth token. All requests must be made over HTTPS.

Authenticate with a Bearer Authorization Header

curl -X $HTTP_METHOD -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" "https://api.digitalocean.com/v2/$OBJECT"

Generate Image, Audio, or Text-to-Speech Using fal Models. This endpoint starts an asynchronous job and returns a request_id. The job status is QUEUED initially. Use the request_id to poll for the result.

Request Body: application/json

input object required

The input parameters for the model invocation. Fields vary by model type.

For image generation models (e.g., fal-ai/flux/schnell, fal-ai/fast-sdxl), use prompt along with optional image parameters like output_format, num_inference_steps, guidance_scale, num_images, and enable_safety_checker.

For audio generation models (e.g., fal-ai/stable-audio-25/text-to-audio), use prompt along with seconds_total to control the duration.

For text-to-speech models (e.g., fal-ai/elevenlabs/tts/multilingual-v2), use text with the content you want converted to speech.

curl -X $HTTP_METHOD -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" "https://api.digitalocean.com/v2/$OBJECT"

Creates a model response for the given chat conversation.

Request Body: application/json

frequency_penalty number optional Nullable

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.

logit_bias object optional Nullable

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.

Show child properties
(additional properties) integer optional

Additional properties are allowed.

logprobs boolean optional Nullable

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.

Show child properties
(additional properties) string optional

Additional properties are allowed.

model string required
Example: llama3-8b-instruct

Model ID used to generate the response.

n integer optional Nullable
Example: 1

How many chat completion choices to generate for each input message. Note that you will be charged based on the number of generated tokens across all of the choices. Keep n as 1 to minimize costs.

presence_penalty number optional Nullable

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.

reasoning_effort string (enum) optional Nullable

Constrains effort on reasoning for reasoning models. Reducing reasoning effort can result in faster responses and fewer tokens used on reasoning in a response.

seed integer optional Nullable

If specified, the 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 is not guaranteed.

stop array | string optional

Up to 4 sequences where the API will stop generating further tokens. The returned text will not contain the stop sequence.

stream boolean optional Nullable

If set to true, the model response data will be streamed to the client as it is generated using server-sent events.

stream_options object optional Nullable

Options for streaming response. Only set this when you set stream to true.

Show child properties
include_usage boolean optional

If set, an additional chunk will be streamed before the data [DONE] message. The usage field on this chunk shows the token usage statistics for the entire request, and the choices field will always be an empty array.

temperature number optional Nullable
Example: 1

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.

tool_choice oneOf optional

Controls which (if any) tool is called by the model. none means the model will not call any tool and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools. Specifying a particular tool via {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool. none is the default when no tools are present. auto is the default if tools are present.

top_logprobs integer optional Nullable

An integer between 0 and 20 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.

top_p number optional Nullable
Example: 1

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.

user string optional
Example: user-1234

A unique identifier representing your end-user, which can help DigitalOcean to monitor and detect abuse.

POST Generate images from text prompts

/v1/images/generations
Authorizations: bearer_auth
Http: Bearer

OAuth Authentication

In order to interact with the DigitalOcean API, you or your application must authenticate.

The DigitalOcean API handles this through OAuth, an open standard for authorization. OAuth allows you to delegate access to your account. Scopes can be used to grant full access, read-only access, or access to a specific set of endpoints.

You can generate an OAuth token by visiting the Apps & API section of the DigitalOcean control panel for your account.

An OAuth token functions as a complete authentication request. In effect, it acts as a substitute for a username and password pair.

Because of this, it is absolutely essential that you keep your OAuth tokens secure. In fact, upon generation, the web interface will only display each token a single time in order to prevent the token from being compromised.

DigitalOcean access tokens begin with an identifiable prefix in order to distinguish them from other similar tokens.

  • dop_v1_ for personal access tokens generated in the control panel
  • doo_v1_ for tokens generated by applications using the OAuth flow
  • dor_v1_ for OAuth refresh tokens

Scopes

Scopes act like permissions assigned to an API token. These permissions determine what actions the token can perform. You can create API tokens that grant read-only access, full access, or limited access to specific endpoints by using custom scopes.

Generally, scopes are designed to match HTTP verbs and common CRUD operations (Create, Read, Update, Delete).

HTTP Verb CRUD Operation Scope
GET Read <resource>:read
POST Create <resource>:create
PUT/PATCH Update <resource>:update
DELETE Delete <resource>:delete

For example, creating a new Droplet by making a POST request to the /v2/droplets endpoint requires the droplet:create scope while listing Droplets by making a GET request to the /v2/droplets endpoint requires the droplet:read scope.

Each endpoint below specifies which scope is required to access it when using custom scopes.

How to Authenticate with OAuth

In order to make an authenticated request, include a bearer-type Authorization header containing your OAuth token. All requests must be made over HTTPS.

Authenticate with a Bearer Authorization Header

curl -X $HTTP_METHOD -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" "https://api.digitalocean.com/v2/$OBJECT"

Creates a high-quality image from a text prompt using GPT-IMAGE-1, the latest image generation model with automatic prompt optimization and enhanced visual capabilities.

Request Body: application/json

background string optional Nullable
Example: auto

The background setting for the image generation. Supported values: transparent, opaque, auto.

model string required
Example: openai-gpt-image-1

The model to use for image generation.

moderation string optional Nullable
Example: auto

The moderation setting for the image generation. Supported values: low, auto.

n integer required
Example: 1

The number of images to generate. Must be between 1 and 10.

output_compression integer optional Nullable
Example: 100

The output compression level for the image generation (0-100).

output_format string optional Nullable
Example: png

The output format for the image generation. Supported values: png, webp, jpeg.

partial_images integer optional Nullable
Example: 1

The number of partial image chunks to return during streaming generation. Defaults to 0. When stream=true, this must be greater than 0 to receive progressive updates of the image as it is being generated.

prompt string required
Example: A cute baby sea otter floating on its back in calm blue water

A text description of the desired image(s). Supports up to 32,000 characters and provides automatic prompt optimization for best results.

quality string optional Nullable
Example: auto

The quality of the image that will be generated. Supported values: auto, high, medium, low.

size string, one of: auto, 1536x1024, 1024x1536 optional
Example: auto

The size of the generated images. GPT-IMAGE-1 supports: auto (automatically select best size), 1536x1024 (landscape), 1024x1536 (portrait).

stream boolean optional Nullable
Example: false

If set to true, partial image data will be streamed as the image is being generated. The response will be sent as server-sent events with partial image chunks. When stream is true, partial_images must be greater than 0.

user string optional Nullable
Example: user-1234

A unique identifier representing your end-user, which can help DigitalOcean to monitor and detect abuse.
