Blockchain And Crypto x402 offerings

Is this x402 endpoint working right now? Give one endpoint URL from the Coinbase Bazaar catalog; get a live payment-challenge check, its current price quote, its 7/30/90-day check history and paying-wallet trend, and a plain verdict: ok, slow, unstable or failing. Uncharged when the URL is not in the catalog.

Real-time Solana mainnet health metrics: current slot, epoch progress, average TPS from recent performance samples, and median priority fee. Use when an agent needs chain liveness and congestion signals before submitting transactions.

Blockchain network statistics — hashrate, total supply, staked amount, transaction count and difficulty; chain analytics API. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-network-stats","request":"<input>"}.

Validates the pair of prefix and origin AS against the RPKI repository and returns the verdict together with every ROA that bears on it: the authorised origin, the prefix it covers and the maximum length it permits. The three outcomes are kept strictly apart because they mean different things and one of them is routinely misread. Valid means a ROA exists and covers exactly this combination.

Collects the observable signs of a route hijack for one prefix and reports which of them are present, with the measurement behind each. Four signs carry different weight. RPKI invalidity is the only hard one: a ROA exists and does not authorise this announcement. An origin AS that appears in the current state but nowhere in the history window is the classic sign, and the response gives the historical origins so the change can be dated.

Counts BGP updates for a prefix or an autonomous system in a recent window and compares them against a baseline built from a longer preceding period for the same resource. The comparison is deliberately self-referential: an AS with a hundred prefixes has a different normal than one with ten thousand, and a fixed threshold is blind for the first and a permanent alarm for the second.

Returns the neighbouring autonomous systems observed next to a given AS in BGP paths, each with the number of observers that saw the adjacency and how often it appeared, which together indicate how solid the observation is rather than how important the relationship is.

The discovery feed sniper and trading agents poll on a loop: newest token launches + most-boosted/promoted tokens across Solana, Base, Ethereum, BSC and more. Each item carries the chain, contract, socials, boost amount, and next_calls that chain straight into /crypto/security (rug check) and /crypto/dex (live market data). Top-of-funnel for the whole trading lane.

Returns the latest newly created onchain pools from CoinGecko.

Arc fresh launches, REAL TIME, each with a sell verdict and a bundle verdict, including the Argus launchpad (measured 6 Oct 2026: 45 of 52 Argus launches in a 2-hour window were in the feed). About 9 in 10 new USDC-paired Uniswap v4 pools on Arc (94 of 107 in that window) are caught by a WebSocket on PoolManager Initialize and exit-checked ~12 s after they open (the watcher drops the oldest job when its queue passes 60), so you learn whether a launch can actually be sold before you buy it.

New token launches on Base and Ethereum, risk-checked: every new pool against ETH, WETH or USDC on Uniswap v2/v3/v4 and Aerodrome in the last hour, with liquidity, sell simulation (honeypot check), Uniswap v4 hook powers, first trades and a verdict (LOW_RISK, CAUTION, HIGH_RISK). Filter by liquidity and verdict. Use to find fresh tokens.

Arbitrum One: Newest DEX pools / token launches on a chain, minutes after creation: token, price, liquidity, volume, buys/sells and creation time. Feed for sniper and screening agents (pair with /token/verdict). $0.02 per call.

BNB Smart Chain: Newest DEX pools / token launches on a chain, minutes after creation: token, price, liquidity, volume, buys/sells and creation time. Feed for sniper and screening agents (pair with /token/verdict). $0.02 per call.

OP Mainnet: Newest DEX pools / token launches on a chain, minutes after creation: token, price, liquidity, volume, buys/sells and creation time. Feed for sniper and screening agents (pair with /token/verdict). $0.02 per call.

Polygon PoS: Newest DEX pools / token launches on a chain, minutes after creation: token, price, liquidity, volume, buys/sells and creation time. Feed for sniper and screening agents (pair with /token/verdict). $0.02 per call.

A tight 4-6 sentence crypto market recap an agent can ingest whole — direction and why, the 2-3 developments that matter, anything notable on the top-10 board — plus the ranked stories as typed fields: stories[] (rank, title, whyItMatters, url, publishedAt, source; linked by exact title, null when unmatched). Distilled from the Otto news engine; served while fresh, refreshed on demand.

Fetch NFT collection (ERC-721 / ERC-1155) metadata by contract address on Ethereum, Base, Polygon, Arbitrum, or Optimism: name, symbol, token type, total supply, deployer, OpenSea slug + image, floor (ETH), Twitter/Discord, and verification (safelist) status. Use to label a contract address with its collection identity before pulling tokens or sales.

Get the current floor price for an NFT collection across OpenSea + LooksRare (Ethereum). Returns per-marketplace floor (ETH), collection URL, retrieval timestamp, and the cheapest cross-marketplace floor with the marketplace tag. Use to price a collection without scraping marketplace UIs, or to detect cross-venue arbitrage gaps.

Return the NFTs owned by a wallet address on a given network. Each row carries the collection name, contract address, token ID, image URL (where available), and ERC-721 vs ERC-1155 standard. Up to 100 per call - paginate with `pageKey` from the previous response.

Resolve the metadata for a single NFT: title, description, image URLs (original + cached CDN), attributes/traits, and the standard (ERC-721 vs ERC-1155). Useful when you have a contract+tokenId and need the display data without re-fetching the whole collection.

Who owns a specific NFT right now, and where its metadata lives: ownerOf, tokenURI, and the collection's name and symbol in one call, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Read from the contract rather than an indexer, so it is correct for tokens minted seconds ago and for collections no marketplace has picked up. Classifies the tokenURI (ipfs / on-chain data URI / http) so an agent knows how to fetch it, and when ownerOf reverts it says which of the three real causes appl

Use when an agent must decide whether an NFT is still held by who it thinks: the current owner of an ERC-721 token id, with its tokenURI and the collection name in the same call, read straight from the contract with no indexer in between. Do not use for a whole wallet's holdings or for ERC-1155 balances: this answers one token id. No API key, no account.
