Every API call that reaches the platform and returns a 2xx response counts against your monthly quota. Failed requests with 4xx or 5xx status codes do not consume quota, with one exception: 429 responses caused by exceeding your own limits are not billed either — they simply are not served.

Rate limits cap sustained requests per second (with burst capacity equal to the limit); quotas cap total requests per calendar month across all APIs combined. Both are visible on every response via X-RateLimit-* and X-Quota-* headers, so your client can throttle proactively.

Requests return 429 with the stable code QUOTA_EXCEEDED until you upgrade or the quota resets on the first of the month (UTC). There are no automatic overage charges — you will never receive a surprise invoice.

Each account has a single API key that covers every API in the catalog. The key is displayed once at creation and stored only as a salted hash. You can rotate it instantly from the dashboard; the old key stops working immediately.

Responses reflect publicly available information at the moment of collection, and every response tells you exactly when that was: the meta.as_of timestamp. Data points that stop being publicly available cannot be served — see the versioning policy for how such external changes are handled.

We target 99.9% monthly uptime, measured by synthetic checks published on our status page. The platform is built on redundant serving paths with automatic recovery, so single failures are absorbed without customer impact. Enterprise agreements include a contractual SLA with service credits.

Yes. The complete platform is described by an OpenAPI 3 document generated directly from the same schemas the gateway enforces at runtime — the spec cannot drift from actual behavior.

Yes. Billing runs through Stripe; you can upgrade, downgrade or cancel from the customer portal at any time. Plan changes apply according to Stripe proration rules; cancellation stops renewal at the end of the current period.

All plans include support via support@endpointry.com with responses within one business day. Growth and Scale plans receive priority handling, and Enterprise agreements include dedicated support with response-time commitments.

Yes. Enterprise plans include contractual SLAs with credits, a Data Processing Agreement, security questionnaires and custom volume or throughput. Contact sales to start the conversation.
