OpenAPI-generated Worker binding catalog

Each capability is a deployable Worker wrapper around one API:

• A generated WorkerEntrypoint with namespaced methods you can bind from another Worker.
• A capa.manifest.json with the source spec, upstream URL, auth style, and operation count.
• One upstream HTTP request per method call, with a structured receipt returned alongside the result.

Install direction

The catalog is moving toward one boring, useful command:

npx @acoyfellow/capa add <capability>

It should drop a hello-world Worker scaffold with the service binding already filled in. No registry theater; just a fast path from “I want Stripe/GitHub/Twitch” to a runnable Worker. Projects.dev can provision provider services and credentials; capa’s install path should make those APIs feel native inside Workers.

Adding a new capability

The catalog above is rendered from capabilities/*/capa.manifest.json at build time. You have two good options:

• Generate a capability locally and use it only in your own account.
• Send a capability to this repo if the API is broadly useful.

For a repo contribution:

1. Run the codegen CLI against an OpenAPI/Swagger spec.
2. Codegen writes capa.manifest.json alongside the generated source.
3. Follow the contribution guide and run bun run check.
4. Open a PR. The catalog picks it up automatically on the next build.

Invariants every capability honours

Property	Value
Public HTTP route	fetch() returns 404
Side effects per method	One upstream HTTP request
Return shape	{ result, evidence }
Returned receipt	Plain JSON, no streams or handles
Auth	wrangler secret put
Billing	Caller-pays

See Reference for the full return shape, codegen flags, and per-capability secret names.
