How this service works
Data about the x402 market: the CDP Bazaar's listings, sellers, prices and categories, new listings and price changes from snapshots every 6 hours, uptime we measure for every paid listing, and x402 spending of any wallet and revenue of any seller on Base.
Output
Returns a JSON object with: total number of distinct origins (sellers/domains), total listing count, a price distribution object with p10/median/p90 in USD, and the count of listings that have 5 or more distinct payers — giving a quick macro-level snapshot of the x402 paid-API market.
Example use cases
Market size check for x402 ecosystem
“How big is the x402 market right now? I want to see the total number of listings, origins, and what prices look like across the board on the CDP Bazaar.”
Tracking median API price over time
“What's the current median price of x402 API listings, and how does the spread look from the cheapest 10% to the most expensive 10%?”
Gauging x402 adoption by payer activity
“How many x402 listings on the CDP Bazaar have at least 5 paying users? I want to understand how many APIs are actually getting real traction.”
Technical details
Endpoint
GEThttps://data.kagurazaka.dev/v1/market/overview?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap ($0.002 USDC) top-level summary of the entire x402 market rather than drilling into individual listings, seller details, or wallet spending. Prefer this for dashboards, trend monitoring, or quick sanity-checks on ecosystem scale. Choose sibling endpoints when you need per-listing uptime, specific wallet spending, seller revenue, or category breakdowns.
Side effects
- Payment required (402) if the x402 micropayment of $0.002 USDC is not attached to the request
- Data may be up to 6 hours stale as snapshots are taken every 6 hours
- No filtering or query parameters supported on this overview endpoint — returns aggregate data only
- Service unavailability or timeout if data.kagurazaka.dev is unreachable
