description: >-
  API Snap enforces rate limits per API key. Documented limits come from the
  pricing page as monthly request quotas (100 / 5,000 / 50,000 / 500,000 calls
  for Free / Hobby / Pro / Business tiers) and from the OpenAPI spec which
  declares a 429 response on every operation. Per-second or per-minute burst
  ceilings are not published on the public site as of profiling; the
  X-RateLimit-Limit and X-RateLimit-Remaining response headers are documented
  on the docs page and a structured 429 body returns `usage`, `limit`, and an
  `upgrade_url`. reconciled is false because per-second burst numbers are not
  publicly published.

policies:
  - name: Single key across all endpoints
    description: One API key (snp_ prefix) authorizes every endpoint in the platform; quotas and rate limits are enforced per key, not per endpoint.
  - name: Quota reset
    description: Monthly request counters reset on the billing cycle anniversary.
  - name: Throttle response body
    description: HTTP 429 responses include a JSON body with `usage`, `limit`, and an `upgrade_url` pointing to https://api-snap.com/pricing so clients can prompt users to upgrade in-product.
  - name: Rate limit headers
    description: Every response includes X-RateLimit-Limit and X-RateLimit-Remaining headers so clients can implement adaptive throttling.
  - name: Custom limits at Business tier
    description: The Business plan advertises "custom rate limits" - bespoke limits should be confirmed with sales.
