GET /index the public index: every endpoint we know and what happened when we actually called it (MCP: guild_index; A2A: 'index') GET /index/search?q= search it POST /envelopes/issue PAID: seal a caller-authenticated payload digest + recipient + nonce + expiry; the payload stays private; verify is FREE. One-call Node buyer: GET /sdk/agentguild_envelope_client.mjs GET /preflight/deep?url= PAID: adds drift history, cross-source corroboration and an explicit allow/caution/ block policy verdict POST /evidence/bundle PAID: a signed snapshot you keep and verify offline, without calling us POST /watch PAID per cycle: continuous monitoring you provision yourself - no onboarding, no human GET /pricing what the paid layer costs, and why ## Free Agent Passport (acquisition, not the paid product) Three free calls make your standing portable and verifiable anywhere: 1.
