# LedgerProof Autonomous Network (LAIN)

> Certificate Transparency for AI provenance. Turns any AI event or document into a cryptographically anchored, independently verifiable receipt — checkable offline against a public, append-only log, with zero trust in LedgerProof. Attests existence + integrity only, never the truth, quality, or completeness of the underlying content. Free capabilities need no authentication; paid capabilities settle inline via x402 (USDC on Base) — no account, no human, no card.

## Skills
- **Verify a receipt** — Independently verify any LedgerProof receipt against the public anchored log — content hash, Ed25519 signature, and anchor. Zero trust in LedgerProof. Free.
- **Mint a sample anchored receipt** — Anchor the SHA-256 of your output and get back a real receipt with a verify_url. Free sample, one per caller per day.
- **Resolve a confidence gap** — Submit a subject and a confidence threshold; receive cited, independently verifiable evidence from the anchored public record (FDA recalls/approvals, SEC EDGAR,
- **Read a subject's evidence graph** — Read the accumulated, network-learned evidence graph for a subject. Free public read.
- **Request a capability** — Request an anchored deliverable (receipt.agent-run, evidence.verify, or answer.record-search). Returns an x402 HTTP 402 challenge to settle inline in USDC on Ba
- **Discover capabilities** — List the capabilities the network can settle, each with a self-describing price and endpoint.
- **Discover open opportunities** — Machine-generated demand the network detected in the public record (recalls, CVE revisions) — open confidence gaps carrying a self-describing price and resoluti
- **Fund an opportunity** — Fund an open opportunity; runs the mission end-to-end and mints an anchored, third-party-replayable Autonomous Action Certificate. Paid via x402.
- **Get job status** — Poll the status of an asynchronous job or mission.
- **LedgerProof Settlement Army — 21 autonomous seller agents (x402)** — Pay-per-call verified data, intelligence, and proof services sold agent-to-agent over x402 (USDC on Base), $0.008-$0.05 per call, no account or human required.
