Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).","url":"https://x402-seller-m8nx.onrender.com/onchain/token","method":"GET","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method"],"properties":{"type":{"type":"string","const":"http"},"method":{"enum":["GET"],"type":"string"},"queryParams":{"type":"object","required":["query"],"properties":{"chain":{"enum":["base","eth","solana","bsc","polygon","arbitrum","optimism"],"type":"string","default":"base"},"query":{"type":"string"},"address":{"type":"string"}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"dex":"uniswap","chain":"ethereum","query":"PEPE","token":{"symbol":"PEPE","address":"0x6982…"},"source":"dexscreener","price_usd":0.0000271,"volume_24h":5200000,"liquidity_usd":14000000,"price_change_pct":{"h1":0.3,"h24":-4.6}}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.01","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.01/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.01","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.01","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_NeNUgFhFhlbtzPhibhDTc","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.01","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Fetches on-chain token data (price, pool, and metadata) for a given token query or address on a specified chain","exampleAgentPrompt":"Can you look up the on-chain token data for the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — give me its current price and pool info?","exampleUseCases":null,"resultDescription":"Returns an object containing on-chain token data for the queried token, which may include current price, DEX liquidity pool details, token metadata, and other chain-specific information relevant to the token.","failureModes":["Token address not found on specified chain — returns empty or error object","Invalid or unsupported chain identifier — returns error","Ambiguous query string with no matching token — returns no results","Upstream on-chain data provider unavailable — service timeout or 5xx error","Payment not included or insufficient USDC — HTTP 402 response"],"whenToPreferThis":"Use this endpoint when an AI agent needs a quick, keyless on-chain token data lookup without stitching together multiple free APIs.
