What a given operation SHOULD cost on Arc right now, in dollars - a price list computed at the gas price read at this block, and the companion to /api/x402/arc-gas which measures what transactions ACTUALLY cost across a spread of blocks. Use this one to quote an operation, that one to budget for the tail: the 20 gwei floor holds most of the time but is not a cap, and the response says so.

Arc pre-trade risk in microseconds, no chain call: pass ?hook=0x… and get the verdict read straight out of the Uniswap v4 permission bits encoded in the hook address. It tells you what the hook is ALLOWED to do (run on every swap, rewrite the amounts, touch liquidity), not what it does: permission is not behaviour. No trap rate is quoted - the 83.7% we used to state came from a pre-buy sell quote and was withdrawn on 2026-09-22 after a real round trip sold 10 of 10 pools with that signature.

Did that Arc payment actually land? Pass ?tx=0x… and optionally ?to=0x… and ?expect=1.50 to get the payer, the amount, whether it reached your address, confirmations, finality and the gas paid — all in USDC. Handles the thing that breaks most Arc integrations: USDC is the NATIVE gas token at 18 decimals in tx.value AND has a 6-decimal ERC-20 view, so a verifier that only reads Transfer logs reports real payments as zero. Read-only: checking never consumes the payment.

Web search with page content for AI agents: send keywords and get the top results with each page read as clean Markdown, in one call: title, URL, a short description and the page's text. Up to 5 results, each page cut at 20,000 characters. Pages that cannot be fetched are dropped and refunded. Pay per call in stablecoins.

X1 wallet threat report, per call: pass ?wallet=<address> and get that wallet's blacklist status, its links to known rug operators and the live alerts against it. Same answer the 5 XNT subscription gives, but priced per lookup so you do not have to commit — pay in USDC on Arc, Base or Solana, or XNT on X1.

Every agent registered on Arc (ERC-8004 identity registry) with its agentId, owner and registration file — the full directory of who is operating on Arc, read from the chain. The free endpoint returns only the count and the first few.

What it really costs to bring USDC into Arc over Circle CCTP, measured from arrivals rather than quoted. Every arrival we hold with its recipient, the amount credited, the fee CCTP took and the transaction, plus observed fees grouped by transfer size. Read from MintAndWithdraw on TokenMessengerV2 0x28b5a0e9C621a5BadaA536219b3a228C8168cf5d, whose event signature we verified by hashing it rather than assuming it, and filtered to the USDC contract on every single log.

Crypto trading signals for BNB Chain majors (BNB, CAKE, BTCB, ETH): BUY 8% below the 24 h high if it still sells in simulation, target +8%; every result published. BNB Chain dip signals on established coins only: BNB, plus tokens on PancakeSwap’s curated default list whose V2 pool against WBNB holds $1M+ (BNB, CAKE, BTCB and ETH on 7 Oct 2026).

Arc token check: can you sell it, and what can its owner do? Safety score plus owner powers in one call. Everything about an Arc token in one call: can you sell it (a real buy-and-sell round trip through its Uniswap v4 pool, the pool fee and the hook permission bits, as a 0-100 safety score with reasons) AND what its owner can do to holders (mint, pause, blacklist, fees, upgradeable proxy, who owns it), read from the bytecode. Cheaper than the two checks bought separately.

Every signed x402-style payment on Arc since launch, read from the chain (plain USDC transfers carry no marker of what they paid for and are not counted): each EIP-3009 authorization spent on Arc USDC (AuthorizationUsed on 0x3600..., joined to the transfer it moved, in either of the two forms Arc logs it) and every Circle Gateway batch (net flows per address, decoded from submitBatch).

X1 chain (not Arc): top traders leaderboard ranked by NET XNT FLOW per wallet and token - XNT received from sells minus XNT spent on buys. It is NOT realized profit and loss: there is no cost basis, so a wallet still holding what it bought looks like a loser and one that sold an airdrop looks like a genius. The MCP twin was corrected on 2026-09-17 and this paid description was missed until the 2026-09-22 audit. For a cost-basis view use /api/x402/wallet, which prices the position proportionally.

The EURO rail on Arc, which nothing else reports. Circle EURC (0xbEf5f6d51CB62b58e6A8f77868681825C6fe21c1) is live on Arc and every other Arc data product, ours included until now, is about new launches and the people sniping them. You get every EURC transfer in the scanned window with from, to, amount, block and transaction, the full top-10 net receivers and senders, and the live counts in summary.

Heuristic on-chain labels for any address - contract vs EOA, activity tier, balance band and transaction count - on EVM chains. wallet label, address classification, eoa or contract, wallet activity, address profile, wallet tag, address label, onchain identity, smart money Accepts payment on Base or Solana — either network works.

Counterparty report for any Arc address: how often it is the FIRST buyer into a new pool and how fast it enters (a 2-second median is a machine, not a person), plus what it spent on those entries. IMPORTANT LIMIT: our scanner records only a pool's first buyer and only that pool's first 8 swaps, so later sales are NOT observed — treat the money figures as entry spend and early exits, not a full ledger. Behaviour, not identity; absent from our index means unknown, not safe.
