What is Discovery?

The Corbits Discovery Service is a registry and search engine for APIs hosted on Corbits. When a merchant registers a proxy through Marketplace, Discovery makes that proxy findable — by developers, by AI agents, and by any programmatic client that can query the catalog. Agents don’t need API keys, accounts, or billing setups. They search Discovery, inspect an API’s OpenAPI spec and pricing, then make pay-per-call requests using a crypto wallet. The Corbits Skill makes this even simpler — install it in Claude Code or OpenCode and your agent can search, browse, and call APIs with a few slash commands.

​
Two sides of Discovery

Discovery connects two groups:
  • Merchants — register your Marketplace proxy with Discovery so it appears in the catalog and becomes findable
  • Consumers — search the catalog, inspect endpoints, and call APIs without any prior registration

Registering your proxy with Discovery

Built a proxy in Marketplace? Register it with Discovery so people can find it.Once your proxy is active in Marketplace, you can register it with the Discovery Service. Registered proxies appear in search results and expose their OpenAPI spec and per-endpoint pricing to any agent or developer querying the catalog.
To get your proxy listed:
  1. Build and activate your proxy in Marketplace
  2. Submit it for listing — see Marketplace Proxies
Once listed, your proxy is immediately visible in Discovery search results.

How agents discover and consume APIs

1

Search

Agents query the Discovery API or use the Corbits Skill to search for APIs by name, category, or capability. Results include pricing, endpoint descriptions, and OpenAPI specs.
2

Evaluate

Each listed proxy exposes its full OpenAPI specification. Agents inspect available endpoints, request/response schemas, and per-endpoint pricing before making a call.
3

Call and pay

The x402 protocol handles payment negotiation automatically. The agent’s wallet signs a payment, the facilitator settles it on-chain, and the API responds — all in a single round-trip.
