How this service works
Search every indexed x402 resource across Coinbase Bazaar, Agent402 and Agentic Market in one call (7k+ tools): name, description, price, seller, network and real usage metrics (calls, unique buyers, settled volume), with per-source freshness data. The meta-tool for agents: find the right paid tool for any task first, then call it.
Output
Returns a ranked list of matching x402 resources, each with: tool name, description, URL, price in USDC, seller identity, blockchain network, usage metrics (total calls, unique buyers, settled volume), source marketplace (Bazaar/Agent402/Agentic Market), and per-source freshness timestamp.
Example use cases

Technical details
Endpoint
POSThttps://agentbit.app/v1/x402/discoverWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover the right paid tool for a subtask before calling it — especially when the agent doesn't know which specific x402 API to use, wants to compare pricing or usage across Bazaar, Agent402, and Agentic Market simultaneously, or needs to find the most popular or cost-effective option for a given capability. Prefer this over hardcoded tool selection when the tool landscape may evolve or when price/volume optimization matters.
Side effects

- Invalid CAIP-2 network string returns validation error
- max_price of 0 or negative may return no results
- source enum value misspelled returns error or empty
- limit above 100 may be capped or rejected
- Stale data if a marketplace source has not refreshed recently
