How this service works
Search the x402 market by keyword or category and get offers ranked by real repeat usage (payers, calls per payer, last payment, price) from a daily survey of the Coinbase Bazaar. Without a query it returns the category overview with demand figures. Helps agents pick services that others actually keep paying for.
Output
Returns a ranked list of up to 25 x402 API offers matching the query or category, each scored by real repeat-usage signals including payer count, calls per payer, last payment date, and price. Without a query, returns a category-level overview with aggregate demand figures across all market segments.
Example use cases
Picking a reliable LLM API
“Search the x402 market for LLM services and give me the top 5 ranked by how many payers keep coming back — I want to pick one that agents actually trust enough to pay repeatedly.”
Category demand overview for crypto
“Pull the x402 market overview for the crypto category so I can see which services have the most demand and what price range they're in.”
Finding a used travel API
“Search the x402 marketplace for 'travel' and show me up to 15 results ranked by repeat usage — I need to pick a flight or booking API that others are actually paying for.”
Technical details
Endpoint
POSThttps://x402op-edge-39830b.fly.dev/p/x402-market?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover which x402-protocol APIs are actually being used and paid for repeatedly in practice — not just listed. It's especially valuable over static API directories when you want demand-signal-ranked results (payer count, repeat calls) rather than self-reported popularity. Prefer it over general web search when scoping discovery specifically to the x402/Coinbase Bazaar ecosystem.
Side effects
- No results found for obscure or misspelled query keywords
- Category enum value not recognized returns validation error
- Limit exceeding 25 returns error or is clamped
- Stale data if daily survey has not yet refreshed
- Network timeout if Coinbase Bazaar data source is temporarily unavailable
