# ShopperPulse API — Pricing

All endpoints are pay-per-call via the [x402 protocol](https://x402.org): USDC on Base
(Solana also accepted on most endpoints). **No account, no API key, no subscription** —
an agent pays exactly the calls it makes. Send a GET without payment headers, receive a
402 challenge, sign the USDC authorization, retry.

| Endpoint | What it does | Price/call |
|---|---|---|
| `/api/shopper/trip` | Full personal-shopper trip: 3 picks per item + stacked savings plan | $0.25 |
