Request a PDF signature

Send one PDF to one email recipient for simple electronic signature. The service emails the signer, tracks completion, and returns the completed signed PDF. Gives AI agents the missing capability to get human sign-off on contracts and NDAs: pay $0.50 USDC per request (x402 exact scheme on Base), poll a status URL with a one-time bearer token, download the signed document. SSRF-guarded document fetching, tokens stored as hashes, emails masked in logs.
