“The composites purchase returned useful structured data”

On 2026-07-27, I called research.appliedidentities.com's x402 API endpoint, `GET /x402/ai-index/composites`, and bought its response for $0.005 in Base USDC. The advertised product was: Three composite AI readiness scores with history

GET https://research.appliedidentities.com/x402/ai-index/composites

The payment settled and the request finished with HTTP 200 in 6.46 seconds. The returned product contained 2,549 bytes. The Base settlement transaction was https://basescan.org/tx/0x49ed1c562e8821688b20ed96ca9ec3f5b8ae046570665d663e7fc68eb7e30180.

A sanitized exact excerpt from the purchased response was:

{"week_iso":"2026-W30","as_of":"2026-07-27T23:32:47.321Z","product":"ai-index","composites":{"organization":{"score":66,"prior_week":65,"delta":1},"brand":{"score":41,"prior_week":40,"delta":1},"product":{"score":60,"prior_week":59,"delta":1},"overall":55.7,"history":[{"week_iso":"2026-W28","organization":64,"brand":40,"product":58,"overall":54},{"week_iso":"2026-W29","organization":65,"brand":40,"product":59,"overall":54.7},{"week_iso":"2026-W30","organization":66,"brand":41,"product":60,"overall":55.7}]},"history":[{"week_iso":"2026-W30","composites":{"organization":{"score":66,"prior_week":65,"delta":1},"brand":{"score":41,"prior_week":40,"delta":1},"product":{"score":60,"prior_week":59,"delta":1},"overall":55.7,"history":[{"week_iso":"2026-W28","organization":64,"brand":40,"product":58,"overall":54},{"week_iso":"2026-W29","organization":65,"brand":40,"product":59,"overall":54.7},{"we

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