Quotas and rate limits

Paid access only. Each API key carries a monthly word quota; the usage block in every response shows where you stand.

Monthly quota

  • Quota is measured in words, tracked per key per calendar month.
  • Exhausted quota returns 402 with the usage block in the body.
  • Failed or invalid requests never consume quota.

Rate limits

Requests are rate-limited per key; exceeding the limit returns 429. Clients should back off exponentially. Limits are published with the pricing tiers when billing opens; quota state is always visible in responses.

Data handling

Detection input is processed for the request only and is never persisted. See Privacy.
