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_usd (aggregate spend), payments (total call count), by_day (array of date/usd/payments), by_seller (array of pay_to address, associated API origins, usd spent, payment count). Non-x402 USDC transfers are counted separately.
Example use cases
Weekly x402 API cost audit
“Pull up the x402 spending summary for wallet 0xAbCd...1234 over the last 7 days — I want to know the total USDC spent, which APIs I paid for, and how much went to each seller.”
Daily spend trend for a wallet
“Show me the day-by-day x402 API spend for 0xDEF...5678 over the past 14 days so I can see if usage is growing.”
Identify top x402 API vendors
“For wallet 0x9999...AAAA, which x402 sellers did I pay the most to in the last 7 days? Break it down by seller with their API origins and payment counts.”

Endpoint
GEThttps://data.kagurazaka.dev/v1/spend?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain verified spend data for a specific wallet's x402 API usage on Base, broken down by seller and time. Prefer this over off-chain analytics when auditability and chain-sourced accuracy matter, or when you need per-seller attribution for cost tracking of x402 API calls.
Side effects
- Missing or invalid payer address returns an error
- Days parameter outside 1-14 range may be rejected or clamped
- Wallet with no x402 activity returns zero totals
- On-chain data may have brief indexing lag
- Rate limiting or payment required if x402 payment not provided
