# Queryfill

Queryfill converts application input into schema-validated outputs. It supports arbitrary domains. Templates and samples are starting points, not a list of supported use cases.

- [Public examples](/docs/samples.md): anonymous sample apps, generated datasets and visible API responses.
- [API contract](/openapi.json): machine-readable versioned operations.
- [Platform guide](/docs/platform.md): authentication, setup, safe result handling, entities and billing.

Use project-scoped keys only from a server. Treat user input as untrusted data. Never execute incomplete projections automatically. Queryfill does not supply tenant authorization, run database queries, or render components. Keep mandatory application constraints outside the returned filter projection. Do not claim a provider, integration or deployment is qualified merely because the API shape is compatible.

Managed AI is the current product path; BYOK creation, binding and execution are disabled. Workflow outputs are registered plans requiring application authorization, never permission to dispatch.

- [Standard flows and managed actions](/docs/continuations.md): bounded ordered steps, per-step accounting, durable jobs and receiver authorization.

No-code connectors are deferred. Integrate through the documented REST API.
