LedgerProof Settlement Army
ledgerproofhq.io
· ledgerproofhq.io
Pay-per-call evidence for autonomous agents, settled in USDC on Base via x402 — no account, no API key, no subscription. POST a subject with your current and required confidence, and the service assembles independently verifiable evidence and returns it with a free cryptographically anchored hash receipt carrying a verify_url anyone can check without trusting us. Settlement is proof-gated: payment is captured only after the deliverable passes a published acceptance rule that can genuinely fail, so a failed result is never charged for. Part of the LedgerProof Settlement Army, 21 proof-gated services in total.
