Read-only API

Four public operations

GET /api/products — paginated catalog.
GET /api/products/{slug} — public product detail.
GET /api/launch_periods — recent launch weeks.
GET /api/launch_periods/{slug} — one week’s rankings.

Detailed fields and schemas live in the OpenAPI specification.

{
  "products": [
    { "slug": "example-product", "name": "Example Product" }
  ],
  "page": 1,
  "total_pages": 1,
  "total_count": 1
}

Response contract

Limits and errors are explicit

The API publishes RateLimit-Policy on read responses. A 429 response also includes Retry-After; wait for that number of seconds before trying again.

{
  "error": "Rate limit exceeded",
  "code": "rate_limit_exceeded",
  "message": "Rate limit exceeded",
  "resolution": "Wait for the number of seconds in Retry-After before retrying.",
  "details": { "retry_after_seconds": 60 }
}

Capability boundary

A person completes every launch

Reads are open. MCP’s prepare_launch creates a draft; a person then signs in, reviews it, chooses the plan and week, and submits. The machine interfaces do not create accounts, launches, votes, or payments.
