How this service works
Search Coinbase's x402 Bazaar by topic: matching paid endpoints with price, 30-day calls and unique payers.
Output
Returns a ranked list of matching x402 endpoints with their URL, host, service name, price in USD, 30-day call count, 30-day unique payer count, tags, network, and last-called timestamp. Also includes a summary, verdict, source attribution, data freshness timestamp, and any degraded-data warnings or disclaimers.
Example use cases
Discovering APIs for a crypto use case
“Search the x402 Bazaar for any paid endpoints covering funding rates — I want to see what's available, what they cost, and how actively they're being used.”
Competitive landscape research before building
“Before I launch my x402 service, can you search the Bazaar for existing endpoints about 'sentiment analysis' so I know what competition looks like and what prices they charge?”
Finding real-buyer APIs on a topic
“Look up x402 APIs related to 'NFT metadata' in the Bazaar and tell me which ones have genuine payers in the last 30 days along with their pricing.”
Technical details
Endpoint
GEThttps://x402-meta.x402tookit.com/x402-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to discover x402-protocol paid APIs by topic or subject matter and need real market data (pricing, usage volume, buyer counts) to evaluate options. Prefer this over manual Bazaar browsing or sibling endpoints when you have a plain-language topic in mind rather than a known service name or domain.
Side effects
- Missing required query parameter 'q' returns validation error
- Empty or overly broad query returns zero or low-quality matches
- Bazaar data may be stale if the index has not been recently refreshed (degraded flag set)
- Niche or misspelled topics may return no results
- Payment failure ($0.02 USDC) prevents the request from completing
