      "summary": "Tersign is the evidence layer for agent commerce (B2B / machine-to-machine). Agents issue seller-signed EIP-712 receipts and action records; the hosted ledger at https://tersign.ai optionally counter-signs them into per-seller hash chains that anyone can verify without an account. Disputes export as venue-ready evidence envelopes (generic / internet-court / kleros / uma). The SDK and MCP server work fully standalone without the hosted ledger: issue and verify offline, counter-sign later. Record shapes are pinned by public conformance vectors: https://github.com/tersignhq/evidence-record-conformance (Apache-2.0, CI-tested). Verify a live counter-signed record right now: npx tersign verify 0xe5874f1ffe87f0a6dd9eb157730f67b86ee4538b125fe30fcc4e165213dd3fc4 --ledger https://tersign.ai",
