How this service works

x402 market scan: for a topic, the top CDP Bazaar listings and who actually gets paid, measured on-chain: each seller's USDC received in the last 24 hours, payments and distinct payers, plus how many sellers earned nothing and the median price. Real demand before you build. Input: a topic, e.g. 'token security'. No LLM.

Output

Returns a JSON object with the scanned topic, network (Base/EIP-155:8453), an array of top listings each with resource URL, price in USD, 24h USDC received, 24h payment count, and 24h distinct payer count, plus aggregate stats: total sellers, total listings, median price in USD, and count of sellers with zero revenue in the last 24 hours.

Example use cases

Pre-build market validation for new API

“Before I spend time building a new x402 pay-per-call API around 'wallet risk scoring', can you scan the Bazaar and show me how many sellers are in that space, what the median price is, and whether anyone is actually earning USDC from real payers in the last day?”

Competitive landscape for crypto price APIs

“I'm thinking about launching a crypto price feed on the x402 Bazaar — can you pull the market scan for 'crypto price' and tell me how many listings exist, who the top earners are, and how many distinct buyers are active?”

Identifying underserved x402 niches

“I want to find a gap in the x402 market — can you scan for 'DeFi analytics' and show me how many sellers earned nothing in the last 24 hours versus who's actually getting paid, so I can figure out if it's oversaturated or still open?”

When to prefer

Choose this endpoint when you need real, on-chain validated demand data for x402 Bazaar categories before building or pricing a pay-per-call API. It is the only endpoint that combines Bazaar listing discovery with actual USDC revenue and distinct payer counts measured on Base over the last 24 hours — no LLM inference, no guesswork, just chain-verified transactions. Prefer it over generic market research tools when the specific question is about x402 API monetization viability.

On-chain data temporarily unavailable — may return stale or partial results
