LedgerProof LAIN — Verified Evidence for AI Agents (MCP)

LAIN (LedgerProof Autonomous Intelligence Network) is a remote MCP server that sells cryptographically anchored evidence: verified agent-run receipts and existence proofs. Every deliverable's hash is anchored in a public, append-only log and verifies independently of LedgerProof's availability.

The settlement rule is enforced in code: payment captures only after the anchored receipt exists. Failed or unproven work is never charged.

Tools

Environments

• test (default) — simulated money; try the full flow free, including machine-to-machine settlement.

• live — a real purchase: the response returns the anchored proof immediately plus a Stripe checkout URL; the deliverable releases when payment captures against the proof.

What a receipt attests

Existence (this run metadata existed at observed_at) and integrity (any later alteration breaks verification). It deliberately does not attest that the run occurred as described, nor the quality of the agent's work — that scope is stated machine-readably inside every receipt.
