Code

Reference

Gateway validation, this Playground, OpenAPI, documentation and generated SDKs use the same versioned QuoAPI public capability contract.

Authentication

Bearer API keys use gi_test_* and gi_live_* prefixes. Full secrets are shown only once.

Error model

Errors use a stable error.code, human-readable message, request ID and structured details.

Idempotency

Retry-safe write operations prevent duplicate billing and duplicate side effects.

Pricing

Usage for this API family is measured using the request billing unit. Exact retail pricing is resolved by your plan and region.

Common questions

Can I start without production credentials?

Yes. Use a test key and the deterministic sandbox while integrating. Live traffic remains separately gated.

Will provider changes break my integration?

The provider layer is abstracted behind the QuoAPI public contract. Contract versions and diffs make public changes explicit.
