POST /api/prove

unprobed

Receipts for agent payments. Send a Base USDC tx hash, get a settlement proof on Arc with a public verify link. $0.02 USDC on Base. The paying wallet must be the sender or recipient of the USDC transfer (403 otherwise, not charged). Idempotent: an already-recorded tx returns status "existing" with no new Arc write. You are only charged when a proof is returned. Site: https://liquidlogicx.com

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
