Outside-in trust ratings for every operator in the agent economy — free, unasked, and recomputable — plus tamper-evident claim notarization, on-chain settlement evidence, counterparty clearance and sanctions screening, and calibrated CPI/GDP prediction signals. Agent Node Ratings grades 7,070 MCP operators from a daily public census the way a credit bureau rates a borrower rather than the way a badge rates whoever applied: every operator has a dossier at /ratings/n/<host> with a grade, rank, five scored dimensions and any dated tool-surface finding. The rated operator never pays. 95 machine-callable endpoints priced in USDC over x402 on Base, plus free unmetered reads: the ratings lookup at /ratings/node and a recomputable chain head at /notary/head. Political-markets Brier 0.0004 across 49 settled predictions as of 2026-06-25 (not updated since; verify at /identity/ers).

Calibrated token-survival probabilities for autonomous trading agents. Keyless by design: no signup, no API key — pay per call in USDC (x402). /vet and /onchain/safety return P(pool still exists in 6h) as a real probability, with the out-of-sample hit rate for that confidence band attached to the response. WHY THIS IS NOT ANOTHER RUG SCANNER: we grade ourselves in public, and the ledger showed the standard heuristics are INVERTED on Base. Across 1,022 graded tokens, 'ownership renounced' rugged 77.5% while NOT-renounced rugged 4.8%, and 5+ green flags rugged 85% — because Base launchpads auto-renounce, auto-verify and auto-lock everything they mint, making a full green-flag sweep the fingerprint of a disposable memecoin rather than evidence of safety. Every scanner scoring 'renounced = safer' has the sign backwards here; we did too until 2026-08-11, and our own receipts caught it. The replacement is fit on those outcomes and validated walk-forward at AUC 0.954 across 6 chronological folds (retired scorer: 0.545). Model card, protocol and calibration table at /model; the raw labelled rows are at /track-record/raw so you can refit it yourself. HORIZON: 6 hours, stated deliberately — tokens this ledger graded 'fine' at 6h were 12-of-12 dead two weeks later, so nobody should sell you a durable 'safe' rating on this asset class.

Across 1,022 graded tokens, 'ownership renounced' rugged 77.5% while NOT-renounced rugged 4.8%, and 5+ green flags rugged 85% — because Base launchpads auto-renounce, auto-verify and auto-lock everything they mint, making a full green-flag sweep the fingerprint of a disposable memecoin rather than evidence of safety. Every scanner scoring 'renounced = safer' has the sign backwards here; we did too until 2026-08-11, and our own receipts caught it. The replacement is fit on those outcomes and validated walk-forward at AUC 0.954 across 6 chronological folds (retired scorer: 0.545). Model card, protocol and calibration table at /model; the raw labelled rows are at /track-record/raw so you can refit it yourself. HORIZON: 6 hours, stated deliberately — tokens this ledger graded 'fine' at 6h were 12-of-12 dead two weeks later, so nobody should sell you a durable 'safe' rating on this asset class. Also: /alpha/launches launch radar, /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds.
