Seal your options as a hash, the next detected muon determines the outcome, receive a certificate dual-signed with Ed25519 and ML-DSA. Free public beacon; paid decisions settled per call via x402 in USDC, no account or API key. Throughput is bounded by physics: about one event every few seconds. Not for cryptographic key material. The certificate format supports multi-node attestation; the federation protocol is published as an open proposal. Today: one detector, one operator, one attestation per certificate.","tool_descriptions":{"costheta_decide":"Paid commit-and-reveal decision. Send a hash of your options; the next detected muon selects one and you receive a publicly verifiable, dual-signed certificate binding your commitment to that physical event.

Shared by all callers until the next muon arrives; for private, request-bound outcomes use costheta_decide. Not for cryptographic keys.","costheta_witness":"Paid timestamp attestation.
