How this service works
Rug protection and decision-ready intelligence for autonomous trading agents. 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).
Output
Returns a JSON object with an as_of date, source attribution (Yahoo Finance OHLCV), methodology note (volume-weighted price-action estimate), the list of symbols queried, a total_net_flow_usd across all symbols, and a per_symbol array containing each ticker's close price, volume, and net_flow_usd estimate.
Example use cases
Daily Bitcoin ETF demand check
“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.”
Weekly ETF trend for trading signal
“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.”
Single ETF flow snapshot
“What's the estimated net flow into IBIT over the past 5 days? I need the close price and total USD flow to decide whether to add to my position.”
Technical details
Endpoint
GEThttps://x402-seller-m8nx.onrender.com/etf/flows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, single-call estimate of ETF capital flows across multiple Bitcoin ETF tickers without needing to stitch together Yahoo Finance OHLCV data yourself. It is ideal for autonomous trading agents that want a lightweight, pay-per-use institutional demand signal without API key setup. Prefer alternatives if you need tick-level precision, official fund-reported flow data, or flows for non-crypto ETFs.
Side effects
- Missing or invalid 'symbols' query parameter returns an error — symbols is required
- Unrecognized ticker symbols may return null or zero-value flow data
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Yahoo Finance data lag or downtime may result in stale or unavailable as_of dates
- Requesting too many symbols in one call may cause timeout on the Render-hosted service
