costheta_decide | Paid x402 Base mainnet tool: commit-and-reveal decision with a signed certificate. Requires PAYMENT-SIGNATURE and idempotency_key. |
costheta_random | Free public random outcome anchored to the latest signed cosmic-ray coincidence pulse. This is a shared beacon: every caller sees the same latest signed pulse until the next muon arrives. For private commitments and retry-safe paid certificates, use costheta_decide. |
costheta_witness | Paid x402 Base mainnet tool: witness a caller commitment against a signed pulse certificate. Requires PAYMENT-SIGNATURE and idempotency_key. |

"full_description": "Verifiable physical randomness from cosmic-ray muon detections. 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.",
