Enables agents to verify claims with evidence-based truth scores and confidence levels by running a deterministic pipeline of evidence lanes and adversarial checks.
Enables defining and verifying evidence contracts for claims in READMEs, releases, or product pages using constrained verifiers and generating hash-chained receipts and reports.
Provides cryptographic truth infrastructure for AI agents, enabling them to seal content with SHA-256 and Ed25519, verify receipts, anchor them to Bitcoin via OpenTimestamps, generate citations, and audit chains of receipts.
Reference data layer for prediction markets: resolution-clarity grades (A/B/C), named resolution sources with provenance, cross-venue linking, and per-contract eligibility screens across Kalshi and Polymarket. Open,read-only, no key required.
Verifiable document intelligence for AI agents. Extract, summarize, claim-check, and notarize PDFs & URLs with cryptographic proofs, cross-document search, and on-chain attestation via Base L2.
