Creates a completion for the chat message. The Edgee API is OpenAI-compatible and works with any model and provider. Supports both streaming and non-streaming responses.

Authorizations

​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your API key. More info here

Headers

​
X-Edgee-Tags
string

Comma-separated list of tags for categorizing and filtering requests in analytics and logs. Example: production,chatbot,customer-support

​
X-Edgee-Debug
boolean

Enable debug mode to include additional debugging information in the response.

​
X-Edgee-Compression-Model
enum<string>

Compression bundle to apply. Tunes the compressor for the agentic style of the calling client.

Available options:
claude,
opencode,
cursor,
codex

Body

application/json
​
model
string
required

ID of the model to use. Format: {author_id}/{model_id} (e.g. openai/gpt-5.2)

Example:

"openai/gpt-5.2"

​
messages
object[]
required

A list of messages comprising the conversation so far.

Minimum array length: 1
​
max_tokens
integer

The maximum number of tokens that can be generated in the chat completion.

Required range: x >= 1
​
stream
boolean
default:false

If set, partial message deltas will be sent, as in OpenAI. Streamed chunks are sent as Server-Sent Events (SSE).

​
stream_options
object

Options for streaming response.

​
tools
object[]

A list of tools the model may call. Currently, only function type is supported.

​
tool_choice

Controls which tool (if any) the model is allowed to call. Accepts a bare string (none / auto), a typed-mode object ({ "type": "auto" | "none" }), or a specific function reference.

Available options:
none,
auto
​
edgee_tool_ids
string[]

List of Edge Tool IDs to inject (e.g. edgee_current_time, edgee_generate_uuid). Each ID must be activated for your API key. When omitted or empty, only tools with hydration enabled for your org or API key are auto-injected. Invalid or non-activated IDs return 400 with invalid_edgee_tool_ids.

Example:
["edgee_current_time", "edgee_generate_uuid"]
​
edgee_pending_id
string

Pending operation ID when continuing a conversation after Edge Tool execution (e.g. when mixing client-side and Edge Tools). The gateway injects stored Edge Tool results into the message history.

​
tags
string[]

Optional tags to categorize and label the request. Useful for filtering and grouping requests in analytics and logs. Can also be sent via the x-edgee-tags header as a comma-separated string.

​
enable_debug
boolean

When true, the response includes additional debug information. Equivalent to the X-Edgee-Debug header.

​
compression_model
enum<string>

Selects the compression bundle to apply to the request. Equivalent to the X-Edgee-Compression-Model header.

Available options:
claude,
opencode,
codex,
cursor

Response

Chat completion created successfully

​
id
string
required

A unique identifier for the chat completion.

Example:

"chatcmpl-123"

​
object
enum<string>
required

The object type, which is always chat.completion.

Available options:
chat.completion
​
created
integer
required

The Unix timestamp (in seconds) of when the chat completion was created.

Example:

1677652288

​
model
string
required

The model used for the chat completion.

Example:

"openai/gpt-5.2"

​
choices
object[]
required

A list of chat completion choices. Can be more than one if n is greater than 1.

​
usage
object
required

Usage statistics for the completion. In streaming responses, this is only present in the final chunk when stream_options.include_usage is true.

​
compression
object

Token compression metrics. Present in the response when token compression was applied to the request. The usage.prompt_tokens field reflects the compressed token count actually billed by the provider.

​
edgee_pending_id
string

Present when one or more Edge Tool calls were deferred. Pass this value back as edgee_pending_id in the next request to resume the conversation with the tool results filled in.

​
edgee_tools_executed
object[]

List of Edge Tools the gateway executed inline before returning. Empty or absent when no Edge Tools ran.
