ERC-8004 agent directory filtered to what is live: registrations classified by a continuous census of the Base registry, filterable by quality (for example a valid file with a declared service) and by x402 support. Each row has the agent id, owner, payout wallet, what it declares (name, endpoint, skills) and a funding cluster shared with agents paid for from the same account. 100 per page. Free: GET /v1/registry. Trial: /v1/trial.

Token liquidity and momentum snapshot, half a cent: live DEX liquidity in USD, price, market cap, pair age, 1h/24h volume, buy-vs-sell transaction ratio, price change — the raw DexScreener read for any EVM token, one source, no fusion. Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche. Cheapest pre-trade depth check; upgrade to /api/evmtoken ($0.015) for the fused safety verdict or /api/exit-depth for sell-impact modeling.

US safety recalls for a VIN, deterministic. Answers "does this car have open recalls", "is this used car safe to buy", "what NHTSA campaigns cover this vehicle". Decodes the VIN via NHTSA vPIC (year, make, model, body, engine) then lists every NHTSA recall campaign for that vehicle: component, summary, remedy, park-outside and do-not-drive flags. No LLM, no key, public domain.

Full safety report for an ERC-20 token.
