description: 'Rate limit posture for the Token.io Open Banking API. Token.io itself does not publish a single
  global RPS / RPM number for the TPP API; effective limits are governed by (a) PSD2 / Open Banking Standard
  defaults applied per-consent at each connected bank, and (b) any TPP-level limits Token.io applies to its own
  API surface. Token.io recommends rate limiting on a per-consent basis to prevent overuse of bank-side AIS
  endpoints. Consult contract terms for production tenant-level limits.'

headers:
  retryAfter: retry-after
responseCodes:
  throttled: 429
  quotaExceeded: 429
algorithm: per-consent
limits:
  - scope: per-AIS-consent (Open Banking UK default)
    tier: Default
    rule: 4 requests per minute when accessed without PSU present, unlimited PSU-present
    notes: 'UK Open Banking Standard default for AIS endpoints — accounts, balance, transactions, standing
      orders. Bank-enforced upstream of Token.io.'
  - scope: per-TPP global
    tier: Production
    rule: contract-defined
    notes: Token.io applies tenant-level throttling per commercial agreement. Exact RPS / RPM negotiated with
      sales.
  - scope: per-bank
    tier: All
    rule: bank-defined
    notes: Each upstream bank enforces its own PSD2 / Open Banking rate limits. Token.io surfaces 429s and bank
      status via the Reports API at /reports/banks/status.
recommendations:
  - Apply per-consent rate limiting on AIS workflows to stay within bank-side caps.
  - Use the Webhooks API to receive event-driven updates rather than polling.
  - Use the Reports API (/reports/banks/status and /reports/banks/{bankId}/status) to monitor degraded bank
    connectivity before retrying.
