Refuses resolved/closed markets — the signature must precede the outcome. Tamper-evident by construction; verify free at GET /verify. Body: {condition_id, side: yes|no, size_usd?, note?}.

POST/v1/calls Commit a SIGNED live call: an ed25519-signed prediction (yes/no) on an OPEN Polymarket market, chain-linked (prev_hash) and content-addressed (sha256). Refuses resolved/closed markets — the signature must precede the outcome. Tamper-evident by construction; verify free at GET /verify. Body: {condition_id, side: yes|no, size_usd?, note?}. | $0.10 | Base | PayAI | 0 |
POST/v1/calls/:id/resolve Attach the settled outcome to a signed call once the market resolves. Returns BOTH envelopes: the original live-call and a resolution envelope that binds its content_hash (call and outcome welded together). Idempotent — an already-resolved call returns its stored envelopes. | $0.02 | Base | PayAI | 0 |
