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/derivs","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":[],"properties":{"symbol":{"type":"string","default":"BTC"}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"signal":"neutral","symbol":"BTC","funding":{"hourly_rate":0.0000125,"annualized_pct":10.95},"mark_price":63943,"open_interest":{"usd":2514265000,"contracts":39322},"change_24h_pct":0.4}},"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_xEU3Bnni1u4zcAotUyyDQ","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 perpetual futures funding rates and open interest data for a given symbol from the x402-seller derivatives raw feed","exampleAgentPrompt":"What are the current perpetual futures funding rate and open interest for ETH right now?","exampleUseCases":[{"title":"Funding rate arbitrage signal detection","prompt":"Check the current funding rate for BTC perps — I want to know if it's positive or negative and by how much, so I can decide whether to go long or short to collect funding."},{"title":"Open interest spike monitoring","prompt":"Pull the latest derivatives data for SOL so I can see if open interest has spiked recently — I'm looking for signs of leveraged positioning building up before a big move."},{"title":"Regime confirmation for directional trade","prompt":"Get me the current funding rate and OI for DOGE perps — I want to confirm whether the market is overly long before I fade the rally."}],"resultDescription":"Returns raw perpetual futures derivatives data for the requested symbol, including funding rate and open interest metrics from aggregated exchange sources, enabling agents to assess market positioning and funding costs.","failureModes":["Symbol not found or unsupported — empty or error response","Payment not included or invalid USDC x402 payment — 402 Payment Required response","Upstream exchange data unavailable — partial or stale data returned","Invalid symbol format — bad request error","Rate limit or server overload on Render hosting — 503 or timeout"],"whenToPreferThis":"Choose this endpoint when your agent needs raw perpetual futures funding rate or open interest data for a specific crypto symbol in a single keyless, pay-per-use call.
