# AgentFeed Coin Signal

> AgentFeed Coin Signal is a paid API for AI agents from x402.ochinimus.app, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-15).

Returns a comprehensive crypto market signal for a single Hyperliquid perpetual coin, including mark price, liquidations, funding rate, open interest, whale positions, and cascade forecast.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentfeed-coin-signal-3028bf00
```

Example prompt: What's the current market signal for BTC on AgentFeed — give me the mark price, funding rate, open interest, whale tilt, and any liquidation clusters or cascade risk right now.

## When to prefer this

Use this endpoint when you need a consolidated, multi-dimensional crypto market signal for a single Hyperliquid perpetual — especially when you want liquidation heatmap data, whale positioning, cascade risk, and funding all in one call rather than stitching together multiple raw data sources. It is particularly well-suited for trading bots and AI agents that make per-call decisions and need fresh, actionable data without maintaining API keys or accounts.

## Known failure modes

- Payment not received — endpoint returns 402 if no valid x402 payment or prepaid key is provided
- Invalid coin ticker — returns error if the coin symbol is not a recognized Hyperliquid perp
- Stale data warning — individual sub-feeds may have their own staleness thresholds (900s or 1800s); the response includes as_of timestamps per source
- Network or upstream data unavailability — Hyperliquid feed may be temporarily unreachable

## How this service works

Crypto market data for AI agents (liquidations, funding, open interest, prices), Solana pre-trade checks, OFAC sanctions screening, scholarly papers, utilities and fixed-purpose language tasks (OCR, translate, summarize, extract, classify, prompt-injection check, transcribe). Paid per call in USDC over x402 on Solana, Base, Polygon, Arbitrum, Arc, Algorand, Optimism, Monad or Avalanche. High-frequency callers pay half price (minimum $0.0005) through batch-settlement (open a channel once, then off-chain vouchers) on Base, Polygon, Arbitrum or Circle Gateway nanopayments on Base, Polygon, Arbitrum, Arc. No API key or account is needed to pay per call. Bots that cannot pay x402 can buy a prepaid key once ($0.25, $1, $5, $20; page at /keys) and send it as X-AgentFeed-Key: each call then costs half the route price, minimum $0.0005, drawn from the balance (GET /api/keys/balance, free). A 30-day bot pass for /api/liq-feed is $25 flat, with nothing drawn per call (/api/keys/buy-pass).

## Output

A JSON object with: mark price, 1h and 24h price change percentages, funding rate (1h and annualized), open interest in USD and its 1h/24h change, OI rank, liquidation amounts for longs and shorts in the past hour, liquidation clusters above and below the current price, top whale positions with side/entry/size/liquidation price, a whale tilt score, a 15-minute cascade liquidation probability with evidence and threshold, data source freshness metadata per sub-feed, and any flags.
