Marcel Routing API documentation

This is the public, JavaScript-free documentation for the Marcel router. The endpoint reference and schemas below are generated from the same OpenAPI source used by Marcel's SDKs. They contain only public routing endpoints, not private customer or administration endpoints.

Base URL: https://marcel-agent.com/api/v1

• Router OpenAPI YAML

• Live model, pricing, tool, video and voice catalog

• Routing introduction

• Agent discovery index

Authenticate

All /api/v1 operations require a Marcel API key in the Authorization header. Reading /api/catalog and these guides is free and unauthenticated. Authentication is not a bot block: a 401 from an operational endpoint means the caller needs a valid key.

Authorization: Bearer YOUR_MARCEL_API_KEY
Content-Type: application/json

Send a chat completion

from openai import OpenAI
import os

client = OpenAI(
    api_key=os.environ["MARCEL_API_KEY"],
    base_url="https://marcel-agent.com/api/v1",
)
response = client.chat.completions.create(
    model="anthropic/claude-sonnet-5",
    messages=[{"role": "user", "content": "Summarize this business objective."}],
    max_completion_tokens=1024,
)
print(response.choices[0].message.content)

Use the live catalog for available model IDs. max_tokens and max_completion_tokens are aliases; if both are present, their values must agree. The accepted limit is 1 through 32768.

Function calls and worker fallback

On supported models, provide function definitions in tools. When an assistant returns tool_calls, execute the permitted functions in the client. Append that complete assistant message and one tool result per tool_call_id to the next request. Never drop calls when switching models or omit a parallel tool result.

response = client.chat.completions.create(
    model="openai/gpt-5.6-sol",
    messages=messages,
    tools=tools,
    extra_body={"fallback_model": "anthropic/claude-sonnet-5"},
    timeout=210.0,
)
print(response.model)

fallback_model permits one retry on transient provider failure. It is opt-in and must identify the caller's main model. Marcel does not restart external workers, execute tools, or replay their side effects. Insufficient credit, malformed input and client disconnects do not trigger fallback.

Streaming

Set stream: true for OpenAI-compatible SSE. Chat output is buffered: headers and keepalive comments arrive while the upstream works, then content and indexed tool-call chunks are delivered. The stream ends with [DONE] on success; failures are sent as error objects. Clients must process errors, not treat every HTTP 200 stream as successful. Each provider attempt has a 90-second deadline.

Errors and idempotency

Operational endpoints can return 400 for invalid input, 401 for missing or invalid keys, 402 for insufficient prepaid credit, 404 for unknown resources, 429 for rate limits, and 5xx for upstream or server failure. Error responses contain an error object. Chat responses include X-Marcel-Request-Id for diagnostics.

An Idempotency-Key protects supported operations against duplicate work. On chat, reusing a key is rejected; it does not replay a stored response. Do not blindly retry actions or tool side effects. Consult each operation's schema and restrictions below.

Images, video and realtime voice

Image generation returns generated image data; it is not image editing. Video generation is asynchronous: submit a job, poll its status, and retrieve content when ready. Some model/resolution/duration combinations are restricted; consult the catalog and operation schema.

Realtime voice requires explicit recording and audio-processing consent when creating a session. The connection uses a short-lived, one-use session token rather than exposing upstream provider credentials.

Other router operations

The complete endpoint reference covers embeddings, moderation, reranking, text translation, multipart document translation with status and file download, tool discovery, and integrated tool execution. Request fields, response envelopes, content types and authentication requirements are included below.

Keep private data private

These documents do not grant access to accounts or paid API calls. Never paste real credentials into documentation examples. Private portal pages and operational endpoints still enforce their normal authentication and authorization.
