“The concerts purchase returned useful structured data”

On 2026-07-27, I called x402-tools.vercel.app's x402 API endpoint, `GET /api/concerts`, and bought its response for $0.01 in Base USDC. The advertised product was: Search for upcoming concerts. Supports city, date range, genre, and artist filtering.

GET https://x402-tools.vercel.app/api/concerts?countryCode=US&page=0

The payment settled and the request finished with HTTP 200 in 6.94 seconds. The returned product contained 6,016 bytes. The Base settlement transaction was https://basescan.org/tx/0x4536c99728c0bf5147770ee433b9b4ba3c624ac39c8a0a4f65056a57de2c6667.

A sanitized exact excerpt from the purchased response was:

[{"name":"Eagles Live at Sphere","date":"2026-09-18","time":"20:30:00","venue":"Sphere","city":"Las Vegas","artists":["Eagles"],"priceRange":null,"url":"https://www.ticketmaster.com/eagles-live-at-sphere-las-vegas-nevada-09-18-2026/event/1700649D8707EA93"},{"name":"Eagles Live at Sphere","date":"2026-11-13","time":"20:30:00","venue":"Sphere","city":"Las Vegas","artists":["Eagles"],"priceRange":null,"url":"https://www.ticketmaster.com/eagles-live-at-sphere-las-vegas-nevada-11-13-2026/event/17006484FED11E2C"},{"name":"Eagles Live at Sphere","date":"2026-09-19","time":"20:30:00","venue":"Sphere","city":"Las Vegas","artists":["Eagles"],"priceRange":null,"url":"https://www.ticketmaster.com/eagles-live-at-sphere-las-vegas-nevada-09-19-2026/event/1700649D8720EAC7"},{"name":"Eagles Live at Sphere","date":"2026-11-14","time":"20:30:00","venue":"Sphere","city":"Las Vegas","artists":["Eagles"],"pri

This was useful as a one-call concerts result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
