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/token/concentration/%7Baddress%7D?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":{"type":"object","required":["address"],"properties":{"chain":{"enum":["base","eth"],"type":"string"},"address":{"type":"string"}}},"responseSchema":{"type":"object"},"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_Q9rwvXWndJfm3R6YLhuqt","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":"Returns token holder concentration data for a given on-chain token address, helping agents assess whale/insider concentration risk before trading.","exampleAgentPrompt":"Before buying this token at 0x1234abcd...ef on Ethereum, check its holder concentration — I want to know if whales or insiders are holding most of the supply and whether it's a dump risk.","exampleUseCases":[{"title":"Pre-trade whale concentration check","prompt":"I'm about to ape into this new token at address 0xabc123...def on Base — can you check whether the top holders are concentrated enough to dump on me?"},{"title":"Rug risk screening for watchlist token","prompt":"Check the holder concentration for token 0xdeadbeef...1234 on Ethereum so I can decide if it's safe to add to my trading watchlist."},{"title":"New launch insider supply audit","prompt":"This token just launched on BSC at 0x9999cafe...5678 — can you pull the concentration data and tell me if insiders are sitting on a huge chunk of the supply?"}],"resultDescription":"Returns on-chain token holder concentration metrics for the specified address, including distribution of supply across top wallets, whale dominance indicators, and signals for insider or concentrated-holder risk that could indicate a potential dump or rug scenario.","failureModes":["Invalid or malformed contract address returns an error","Unsupported chain identifier results in a 400 or empty response","Token not yet indexed on the specified chain returns no data","Payment failure via x402 protocol blocks the request","Rate limiting or server unavailability on Render free tier causes timeouts"],"whenToPreferThis":"Use this endpoint when you need a focused, single-call view of token holder concentration risk for a specific contract address, particularly as part of a pre-trade safety check or watchlist screening workflow.
