Parameters

Header Parameters

mcp-session-id

required

string

Responses

200

SSE stream opened — messages arrive as text/event-stream events.

text/event-stream

Newline-delimited Server-Sent Events. Each data: line carries a JSON-RPC 2.0 message (same envelope as the POST response). Clients should parse each event’s data attribute as JSON.

string

400

Invalid request — malformed body, missing required attribute, or failed validation. See error and message for details.

application/json

object

error

required

Stable machine-readable error code (e.g. INVALID_STATUS_TRANSITION, BILLING_INSUFFICIENT_BALANCE). Always present.

string

message

Human-readable explanation of the error.

string

code

Alternate machine-readable code — present on some endpoints as an alias for error for backward compatibility.

string

request_id

Opaque support/debug identifier when available.

Examples

validation_error

  "error": "Bad Request",
  "code": "MISSING_SEGMENTS",
  "message": "segment_ids is required for filter audiences."
}

401

Missing or invalid Bearer token. Obtain one via POST /v1/auth/token. When a token was supplied but rejected, code distinguishes TOKEN_EXPIRED (the token’s lifetime has passed — request a new one via POST /v1/auth/token and retry) from TOKEN_INVALID (malformed or revoked — re-authenticate).
