Solana token rug check before you buy: SAFE/CAUTION/DANGER from chain state, paid per call via x402.

Trust score (0-100, grade A-F) for any x402 endpoint, cataloged or not: 30d uptime, 402-envelope compliance, latency, age, real on-chain USDC settlement volume, and price stability, with a full auditable breakdown. Uncataloged endpoints are live-probed on first query and auto-adopted. Know before you pay.

Diagnose x402 protocol and discovery configuration with separate linter and compliance grades. Optional quote_mode fast returns a payable first 402; resend the same input with proof, save the job/capability and poll. Default preserves compute-first admission. Base or Solana, 0.05 USDC per completed scan. Failed or expired unfinished work is uncharged; never replace a pending proof. Reports expire after 24 hours. Probes never pay targets or certify paid delivery.

The whole market read in one small answer — a morning brief for agents: the regime verdict per book (S&P 500, Nasdaq-100, macro, BTC/ETH crypto), today's top-5 buy candidates, the biggest gainers and losers, the crypto trend-gate state, and the awareness read: the five names leading today, sector money flows in and out, the five most coiled setups, coverage. One $0.02 call instead of four. Refreshed ~5 min in US market hours. Research, not advice.

Resolve ENS in either direction on Ethereum: an ENS name (vitalik.eth) → its 0x address, or a 0x address → its primary ENS name (plus avatar when set). The identity read wallet, payment, and UX agents make to verify who they're sending to or to show a human-readable name instead of a raw hex address. Free upstream (Blockscout ENS / live registry); one paid call instead of running your own resolver.

LPC Collection Facts. Collection-level facts for the LPC NFT collection on Polygon: supply, holder count, tier distribution, concentration and marketplace activity. Every response carries the scan time, so the age of the snapshot is never hidden. Aggregates only — no owner addresses, no account-linked data, and not a valuation.

Token info for any Arc token, before an app shows it: name, symbol, decimals, total supply, whether it is Circle's USDC / EURC, who launched it and when (the wallet that sent the launch transaction, with its other launches in 30 days; from our index of launchpad launches, never guessed), its Uniswap v4 USDC pool count and the deepest pool's price and liquidity, and plain risk signals (fake USDC name, under 24 h old, no or one thin pool, a high-volume launcher).
