AgentFeed

Use when an agent needs to know which Hyperliquid perps moved unusually. Returns each coin whose 5-minute, 1-hour or 4-hour price move, or 1-hour open-interest change, is past its own measured tail (tiers from the coin's own history, sample size printed), labelled event-driven when a scheduled FOMC, CPI, NFP or PCE release explains it. An empty list is a valid answer. Stale inputs answer 503, never billed. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Use when an agent needs the text inside an image. Returns the text of a PNG, JPEG, WebP or GIF (5 MB, 4096 px a side) in reading order, as blocks with their line breaks, plus the detected language. It transcribes; it never follows text in the image. Costs 0.04 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Open interest spikes across every Hyperliquid perp: coins whose open interest moved abnormally in the last hour against their own previous day, with the 1h, 4h and 24h change (in coin units, so a price move does not count), a spike z-score, the price move and funding. Read from our own 5-minute sampler: it answers 503 and is never billed until that record is 24 hours deep. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Open interest for ANY Hyperliquid perp: OI in base units and in USD with the mark price, and its 1h and 24h change from our own 5-minute sampler (null until that record reaches back so far). /api/positioning adds the whale net-long share for SOL and BTC. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Orderbook imbalance for any Hyperliquid perp: resting bid and ask liquidity in USD within ±N bps of mid, the ratio between the two sides, and a skew read. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Orderbook walls for any Hyperliquid perp: the largest resting orders on each side of the book, with USD size and distance from mid. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Use when an agent needs the paper behind a DOI. Returns title, year, authors, venue, citation count, open-access URL and the abstract where OpenAlex holds it (CC0 data).

Costs 0.015 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Use when an agent needs the text of a PDF as markdown. Returns the text of the one PDF URL you pass, page by page as markdown, with title, page count and word count. http or https, 10 MB, 10 s; robots.txt honoured and private addresses refused. A file that is not a PDF, a PDF with no text layer (a scan), or an unreachable URL, is never charged. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Tokenized stock peg deviation on Solana: the on-chain DEX price of a tokenized US equity versus the underlying's last real trade, in bps, with 24h stats split into market-open and off-hours. Sampled every 5 minutes by our own collector; the token price is read on-chain. latest.reference is null: the underlying's reference price is not returned (its source does not allow redistribution), only the deviation computed from it. Costs 0.02 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Tokenized stock peg by trading session: deviation broken out across open, premarket, afterhours, overnight and weekend — mean, p95, max bps and median liquidity each, with the worst off-hours window flagged. Market-open acts as the control. Costs 0.03 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Tokenized stocks ranked by off-hours peg risk: every tokenized US equity we track, with p95 and max deviation bps, market-open deviation as the control, and median liquidity. Dead pools are excluded rather than reported as perfect pegs. Costs 0.05 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).

Use when an agent needs one perp market in a single call. Returns Hyperliquid funding and open interest (with 1h/24h change from our 5-minute sampler) and 24h liquidations with long/short split and biggest print from our own tape.

Signal board for trading bots: the Hyperliquid perp market in one table, ranked by open interest in USD (30 coins by default, up to 60, or the coins you list). Per coin: mark, 1h and 24h price change, funding (hourly and annualised), open interest in USD with its 1h and 24h change, liquidations in the last hour by side with a z-score against the coin's own last 7 days, the whale net position and tilt of the top 250 Hyperliquid accounts, and flags: crowded_long (funding_ann_pct >= 30 and oi_chg_24h_pct >= 5), crowded_short (funding_ann_pct <= -10 and oi_chg_24h_pct >= 5), squeeze_risk (crowded_short and (chg_1h_pct >= 1 or liq_1h_short_usd >= 2 x liq_1h_long_usd with liq_1h_short_usd >= 50000)), liq_spike (liq_z >= 3 and liq_1h_long_usd + liq_1h_short_usd >= 50000).

Short squeeze score and long flush score, 0-100, for any Hyperliquid perp. Composite of Hyperliquid funding (35), whale crowding (25: the net-long share of the top 250 Hyperliquid accounts in the coin, not retail), the 24h open-interest build from our own 5-minute sampler (20) and liquidation skew from our own tape (20). One number for whether a trade is crowded and about to hurt someone. A symbol nothing lists answers 400; while the open-interest record is under 24 hours deep, or Hyperliquid or the whale snapshot is unavailable, it answers 503; both are never billed.

SPL token rug-risk signals: mint/freeze authority status (revoked = safer), top-1/top-10 holder concentration, and risk flags. Not a honeypot/LP-lock checker. Costs 0.01 USDC per call (x402, USDC on Solana, Base, Polygon, Arbitrum or Arc).
