SignatureAPI OpenAPI Spec

Download the SignatureAPI OpenAPI 3.1 specification and discover the API programmatically

The complete SignatureAPI specification, in OpenAPI 3.1 format, is available at:

https://spec.signatureapi.com/openapi.yaml

The specification always reflects the currently deployed API. Use it to generate clients, power agent integrations, or explore the API surface.

Programmatic discovery

We also publish an RFC 9727 API catalog at:

https://signatureapi.com/.well-known/api-catalog

The catalog is an RFC 9264 linkset pointing to the OpenAPI specification, this documentation, and the status page. Tools and agents can use it to discover the API from the domain name alone.
