SDK vs HTTP
TypeScript SDK is the current fact source; HTTP is suitable for teams that own retry, idempotency, and error classification.
Current status
This page is intentionally constrained to facts found in @acosmi/sdk-ts@2.0.1 and the local docs audit.
Boundary
The docs center does not claim language SDKs, webhook signing contracts, or OpenAPI coverage that has not been copied into this repository and verified by checks.
