How this service works
What a wallet spent on x402 APIs on Base in the last days, read from the chain: total, per seller (named by the Bazaar listings that pay to it), per day, and the recent payments, with other USDC transfers counted apart.
Output
Returns a JSON object containing: total USD spent on x402 APIs, a per-seller breakdown (sellers named by their Bazaar listings), a per-day spend breakdown, a list of recent individual payments, and any other USDC transfers counted separately — all derived from on-chain Base data.
Example use cases
Track personal x402 API spending
“How much has my wallet 0xDead...Beef spent on x402 APIs in the last 14 days? Break it down by seller so I can see who I'm paying the most.”
Daily spend trend for a wallet
“Can you pull the day-by-day x402 payment history for wallet 0x1234...abcd over the past 7 days? I want to see if my spending spiked on any particular day.”
Audit a wallet's x402 payment activity
“I need to audit wallet 0xFeed...Cafe — show me all its x402 payments on Base from the last 10 days, including which sellers it paid and any other USDC transfers separately.”
Technical details
Endpoint
GEThttps://tb2s28fm0h8dkq2t.68r.lambda-web.us-east-1.on.aws/v1/spend?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to analyze spending patterns for a specific wallet on x402 APIs — especially when you want seller-level attribution, daily trends, or a recent payment log. Prefer this over general blockchain explorers when you specifically want x402 API payments on Base with Bazaar seller names already resolved.
Side effects
- Missing or invalid 'payer' wallet address returns an error
- Days parameter outside 1-14 range may be rejected or clamped to defaults
- Wallet with no x402 activity returns zero totals
- Network or Lambda timeout for wallets with very high transaction volume
- Malformed wallet address (not 0x-prefixed or wrong length) causes query failure
