OpenAPI Specifications

Use these machine-readable OpenAPI specifications to generate client code, drive API tooling, or give an AI agent accurate request and response shapes. Every API in this reference has one. Every spec is hosted at https://developers.circle.com/openapi/ and served as a raw YAML file. Add the filename to that base path to fetch a spec directly:

curl https://developers.circle.com/openapi/cctp.yaml

Available specifications

Specs are grouped by the product they power. A few specs power more than one product, so they appear under each. Where the same filename appears under multiple products, it’s the same file—not a product-specific variant.
