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/signal","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":{"symbol":"BTC","verdict":"bullish","momentum":0.42,"price_usd":63950,"change_24h_pct":0.5}},"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__2NuLcnjr_aVv5-p7n3dU","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 a real-time market signal or price data point for a given token symbol, as part of a broader rug-protection and alpha intelligence suite for autonomous trading agents.","exampleAgentPrompt":"Pull the current market signal for $WIF from x402-seller — I want to see the latest signal data before I make a trading decision.","exampleUseCases":[{"title":"Live signal check before trade","prompt":"Grab the current trading signal for $BONK right now — I need to know whether it's showing bullish or bearish momentum before I enter a position."},{"title":"Automated agent signal polling","prompt":"Every 5 minutes, fetch the signal for $PEPE from the signal feed and alert me if anything changes significantly."},{"title":"Pre-trade signal sanity check","prompt":"Before my agent buys any of this token, can you quickly pull the signal data for $FLOKI so I can see what the market intelligence says right now?"}],"resultDescription":"Returns a JSON object containing market signal data for the requested token symbol — likely including price, signal score, or trend indicators relevant to autonomous trading decisions.
