Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent-data-api-crypto-market-pulse-composite-bb559523
```

Example prompt: Give me the current crypto market pulse — I want to know if we're in a risk-on or risk-off regime right now based on Fear and Greed, BTC dominance, market cap movement, and BTC funding rates all rolled into one signal.

## When to prefer this

Use this endpoint when you need a single synthesized macro signal for crypto market regime rather than raw per-coin price data. Ideal for agents making high-level trading posture decisions, portfolio rebalancing triggers, or risk-on/risk-off switching logic. Prefer over individual sentiment or funding APIs when you want a pre-merged, normalized composite read without building your own aggregation logic.

## Known failure modes

- Upstream data source (CoinGecko, Binance, Fear & Greed) unavailable — returns 503 or partial data
- Payment not settled via x402 USDC on Base — returns 402 Payment Required
- IP or rate limit exceeded — returns 429
- Invalid or malformed request — returns 400
- Server timeout if aggregation across sources is slow — returns 504

## How this service works

Pay-per-call data utilities for AI agents (no API key, settle USDC on Base via x402). WEB: GET /audit?url= → structured site signals; GET /extract?url= → clean readable extraction. CRYPTO (multi-source, one call, cleaned & normalized): GET /snapshot?ids= → per-coin price+market+funding+sentiment merged from CoinGecko/Binance/F&G; GET /spread?symbol= → cross-venue best bid/ask & arb spread across Binance/Coinbase/Kraken/OKX; GET /funding → all perp funding rates, annualized APR, sorted extremes; GET /defi → DeFi macro (total TVL, top chains, stablecoin supply & 24h delta); GET /pulse → composite market-regime read (Fear&Greed + dominance + mcap delta + BTC funding → signal).

## Output

A JSON object containing a composite market-regime signal derived from Fear & Greed index value, BTC dominance percentage, total market cap 24h delta, and BTC perpetual funding rate — synthesized into a single directional indicator (e.g. bullish/bearish/neutral or numeric score) representing the current macro crypto sentiment regime.
