ThoughtProof

AI agents can pay, discover, and act — but nobody checks if their reasoning is sound before they settle. ThoughtProof does. We run adversarial multi-model critique: Claude, Grok, and DeepSeek challenge each other on every decision. If the reasoning holds up, the agent gets ALLOW. If not, HOLD — with specific objections and a confidence score. The result is a JWKS-signed EdDSA attestation that any smart contract hook can verify on-chain, offline, without calling us. Live infrastructure: - api.thoughtproof.ai/v1/check — x402-gated reasoning verification API (returns 402 with payment instructions, then ALLOW/HOLD after payment) - [email protected] — npm install and verify in 3 lines of code - thoughtproof.ai/skill.md — agent-discoverable skill file - JWKS at api.thoughtproof.ai/.well-known/jwks.json Built on Base. Payment via x402 (USDC) and MPP (Tempo/Stripe). We are one of four issuers in the Combined Attestation Standard — a multi-signature verification format where each dimension of trust (wallet state, behavioral trust, reasoning quality, job performance) is independently signed and verifiable.
