AgentCash can discover what endpoints are available on any compatible origin, along with their pricing and schemas.

​
Search for a capability

When you don’t know which origin to use, start with search. It takes a natural-language query and returns ranked providers along with endpoint details and pricing.
Use AgentCash to search for an API that can send physical mail.
Or from the CLI: 
npx agentcash search "send physical mail"
Skip search when the task clearly maps to a registered origin — e.g., people research → stableenrich.dev, image generation → stablestudio.dev. In that case, go straight to discover below.

​
Discover endpoints on an origin

Ask your agent:
Discover available endpoints on stableenrich.dev using AgentCash.
Or use the CLI: 
npx agentcash discover https://stableenrich.dev
This fetches the discovery document from the origin and returns a list of endpoints with their descriptions and pricing.

​
Known origins

AgentCash ships with a set of pre-indexed origins:
OriginDescription
stableenrich.devCompany and contact enrichment via Apollo, Exa, Serper, and more
stablesocial.devSocial media data (Instagram, TikTok, YouTube, Reddit, Facebook)
stablestudio.devImage and video generation
stableupload.devFile hosting
stableemail.devEmail sending
These are available immediately without needing to discover them first.

​
Check a specific endpoint

To inspect a single endpoint’s pricing and schema without paying:
Check the schema for POST https://stableenrich.dev/api/company/lookup using AgentCash.
Or via CLI: 
npx agentcash check https://stableenrich.dev/api/company/lookup
This returns:
  • Price: how much the call costs in USDC
  • Methods: which HTTP methods are supported
  • Input schema: expected request body format
  • Output schema: response format
  • Auth type: whether it uses x402, SIWX, or other auth

​
Discovery protocol

Servers advertise their endpoints as an OpenAPI document at /openapi.json. Each paid operation carries an x-payment-info block with price, currency, and accepted protocols (x402, mpp). AgentCash parses this to build the endpoint index. If /openapi.json is missing, AgentCash falls back to /.well-known/x402 for older servers. Either path makes the server discoverable. See server discovery if you’re building a server and want to be listed.
