“The usage purchase returned useful structured data”

On 2026-07-27, I called NFL Fantasy x402 API's x402 API endpoint, `GET /api/player/usage`, and bought its response for $0.02 in Base USDC. The advertised product was: NFL player usage and opportunity metrics for fantasy football: target share, air yards share, WOPR, Next Gen Stats (separation, YAC over expectation, rush yards over expected) with recent-week trend deltas vs season average.

GET https://nfl-x402-api.vercel.app/api/player/usage?last_n=4&name=Ja%27Marr+Chase&season=2025

The payment settled and the request finished with HTTP 200 in 5.32 seconds. The returned product contained 1,244 bytes. The Base settlement transaction was https://basescan.org/tx/0x9c8d254d4e658b9801318f60c90d462ba45be232b2a13b913a95968a54061476.

A sanitized exact excerpt from the purchased response was:

{"player":{"player_id":"00-0036900","name":"Ja'Marr Chase","position":"WR","last_team":"CIN","first_season":2021,"last_season":2025},"season":2025,"games":16,"window":4,"metrics":{"target_share":{"season_avg":0.32,"last_4_avg":0.33,"trend":0.01},"air_yards_share":{"season_avg":0.366,"last_4_avg":0.41,"trend":0.044},"wopr":{"season_avg":0.737,"last_4_avg":0.785,"trend":0.048},"racr":{"season_avg":1.03,"last_4_avg":1.13,"trend":0.1},"avg_cushion":{"season_avg":5.822,"last_4_avg":6.085,"trend":0.263},"avg_separation":{"season_avg":3.034,"last_4_avg":3.538,"trend":0.504},"percent_share_of_intended_air_yards":{"season_avg":37.108,"last_4_avg":39.87,"trend":2.762},"catch_percentage":{"season_avg":66.812,"last_4_avg":75.525,"trend":8.713},"avg_yac_above_expectation":{"season_avg":1.48,"last_4_avg":1.425,"trend":-0.055},"targets":{"season_avg":11.563,"last_4_avg":11.5,"trend":-0.062},"carries":{

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