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/etf/flows?utm_source=zero.xyz","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":["symbols"],"properties":{"days":{"type":"string","default":"5"},"symbols":{"type":"string"}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"as_of":"2026-07-25","source":"Yahoo Finance OHLCV","per_symbol":[{"close":57.32,"symbol":"IBIT","volume":12000000,"net_flow_usd":80000000},{"close":55.1,"symbol":"FBTC","volume":4500000,"net_flow_usd":30000000},{"close":52.8,"symbol":"ARKB","volume":2100000,"net_flow_usd":15000000}],"methodology":"volume-weighted price-action estimate","symbols_queried":["IBIT","FBTC","ARKB"],"total_net_flow_usd":125000000}},"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_en69OHKBL9fxYOMqvVWlY","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 volume-weighted estimated net flows (in USD) for one or more Bitcoin or crypto ETF ticker symbols over a configurable number of days","exampleAgentPrompt":"Pull the last 5 days of net flow estimates for IBIT, FBTC, and ARKB so I can see which Bitcoin ETF is attracting the most institutional money right now.","exampleUseCases":[{"title":"Daily Bitcoin ETF demand check","prompt":"Give me today's net flow numbers for IBIT, FBTC, and ARKB — I want to know which one is pulling in the most money and what the total combined inflow looks like."},{"title":"Weekly ETF trend for trading signal","prompt":"Fetch the 7-day volume-weighted flow estimates for IBIT and FBTC so I can see whether institutional demand has been accelerating or cooling off heading into the weekend."},{"title":"Single ETF flow snapshot","prompt":"What's the estimated net flow into IBIT over the past 5 days?
