How this service works
x402 Market Feed: ranked paid-resource demand signals from x402 discovery, including 30-day calls, unique payers, price, estimated gross revenue, tags, niche summaries, and a buildBrief with recommended experiments, pricing rules, and do-not-build warnings for agents deciding what crypto/API endpoint to build, buy, or price. The crypto preset is shaped for agents evaluating token-risk, crypto-news, onchain-prefilter, and x402 seller-tool demand.
Output
A ranked list of paid x402 API resources matching the query, each with 30-day call counts, unique payer counts, price per call, estimated gross revenue, descriptive tags, a niche summary, and a buildBrief object containing recommended experiments, pricing rules, and explicit do-not-build warnings.
Example use cases
Identify profitable API niches to build
“I'm thinking about launching a paid API — can you pull the x402 market feed for 'AI' queries, limit to 10 results with at least 3 unique payers, and summarize the top niches with their revenue estimates and any do-not-build warnings?”
Scout competitive landscape before buying an API
“Before I subscribe to any paid data API, show me the x402 market feed for 'finance' with at least 5 payers and up to 20 results — I want to know which ones have the most 30-day calls and what the typical prices look like.”
Weekly API market demand report
“Every Monday, pull the x402 market feed for 'web3' with a limit of 25 and minimum 5 payers, then give me a summary of which niches are trending up, which have the highest estimated gross revenue, and what experiments are recommended in the build briefs.”
Technical details
Endpoint
GEThttps://76.13.79.47.nip.io/token-signal-x402/v1/x402-market-feed?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or developer needs to understand real market demand on the x402 paid-API ecosystem — especially for deciding what API to build, price, or purchase. It is more actionable than raw API directories because it combines live usage signals (calls, payers, revenue) with AI-generated build guidance. Prefer it over generic API marketplaces when the goal is specifically x402-native paid resource discovery.
Side effects
- No results returned if query keyword matches no listed x402 resources
- min_payers filter too high may return empty result set
- Payment not processed (x402 payment failure) results in 402 response with no data
- Stale data if x402 discovery index hasn't refreshed recently
- Invalid query parameter type returns schema validation error
