How this service works
Check an x402 niche before you build or buy. Send {"query":"pdf to markdown"}. Returns matching bazaar listings and hosts, how many have outside paying buyers in the last 30 days, max and median unique payers, price quartiles overall and among listings with demand, top listings and hosts by payers, and a verdict: empty, no-demand, thin-supply, contested, or incumbent-dominated. From Coinbase discovery metrics, refreshed every 6 hours.
Output
Returns a structured analysis including: count of matching bazaar listings and hosts, number with outside paying buyers in the last 30 days, max and median unique payer counts, price quartiles for all listings and for demand-positive listings only, top listings and top hosts ranked by unique payers, and a categorical verdict (empty, no-demand, thin-supply, contested, or incumbent-dominated). Data is sourced from Coinbase discovery metrics and refreshed every 6 hours.
Example use cases
Validating a new API idea
“I'm thinking of launching an x402 service for 'image background removal' — can you check the bazaar demand for that niche and tell me if there are real paying buyers, what the max and median unique payer counts look like, and whether the market is empty, thin, or already dominated?”
Competitive pricing research
“I want to price my 'text summarization' x402 service competitively — can you pull the bazaar niche data for 'text summarization' and show me the price quartiles, especially among listings that actually have paying demand?”
Scouting top competitors before acquisition
“I'm considering buying an existing x402 service in the 'web scraping' niche — can you run the bazaar demand check for 'web scraping' and show me the top listings and hosts by unique paying buyers in the last 30 days?”
Technical details
Endpoint
POSThttps://audit.152-53-82-29.sslip.io/v1/niche?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, data-backed market signal for an x402 service niche before building or purchasing a service. It is uniquely suited for x402/bazaar market research because it draws directly from Coinbase discovery metrics covering real buyer transactions. Prefer it over general web search or manual browsing when you want structured demand verdicts, price quartiles, and ranked competitor data in a single call for micropayment API categories.
Side effects
- Query string too long or exceeds 6 words — endpoint expects concise niche descriptors
- No matching listings found — verdict returns 'empty' with zero counts
- Limit parameter out of range (must be 1–25) — request rejected
- Stale data if queried immediately after a market change — metrics refresh every 6 hours
- Network or payment failure — x402 payment of $0.01 USDC must succeed before result is returned
