Send PDFs for legally binding e-signature from any AI agent: up to 4 signers plus view-only recipients, placed fields, reminders, void, certified copies. Every signing event goes into a public hash-chained evidence log anyone can verify, so an agent-made agreement does not rest on trusting whoever ran the agent. 100 documents a month free, no card; then prepaid per document. Sign in with OAuth or use an API key. Docs: signathing.com/developers
