generated: '2026-08-26' method: searched source: >- Sweep of every reachable PayZen surface on 2026-08-26 for published rate limits. PayZen publishes no developer portal, no API reference and no machine-readable contract, so no limits, windows, burst allowances or response headers are documented anywhere public. limit_count: 0 limits: [] headers: [] exhaustion_status_code: null note: >- An honest zero, not an assertion that the API is unlimited. PayZen's own status page monitors a service named "API" (https://status.payzen.com/), so an API exists — but its runtime limits are only visible to contracted health systems. No X-RateLimit-*, RateLimit-* or Retry-After behaviour could be observed because there is no reachable unauthenticated endpoint to call: api.payzen.com and developer.payzen.com do not resolve in DNS. evidence: - url: https://payzen.com/llms.txt status: 200 detail: Yoast-generated page index; lists marketing pages only, no developer reference. - url: https://payzen.com/docs status: 404 - url: https://app.payzen.com/openapi.json status: 404
