## 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 signalpulse-crypto-lite-market-pulse-def296f9
```

Example prompt: Give me a quick crypto market pulse — current BTC, ETH, and SOL prices with 24h change, the Fear & Greed index, and whether the market regime is risk-on, risk-off, or somewhere in between.

## When to prefer this

Use this endpoint when you need a cheap, fast, and deterministic crypto market snapshot every agent loop cycle (e.g. every 60 seconds) and do not yet need full technical analysis, derivatives data, or a directional call — those require the $2 /api/scan/crypto deep scan. Ideal for routing decisions, pre-trade checks, or dashboard updates where cost efficiency matters.

## Known failure modes

- Upstream price feed outage causing stale or missing price data
- Payment failure (x402) if USDC balance is insufficient
- 503 if the SignalPulse service is temporarily unavailable
- Rate limiting if the endpoint is called faster than the 60s freshness window warrants

## How this service works

Crypto market tick — BTC, ETH, SOL live price + 24h change, Fear & Greed index, and a deterministic regime verdict (RISK_ON / DRIFT_UP / CHOP / DRIFT_DOWN / RISK_OFF) in ONE $0.05 call. Built for agent loops that need a cheap market pulse every cycle; escalate to /api/scan/crypto ($2) for the institutional deep scan with technicals, derivatives and a directional call. 60s freshness, no LLM in the path.

## Output

Returns live spot prices and 24h percentage change for BTC, ETH, and SOL; the current Fear & Greed index value; and a single deterministic regime label from the set RISK_ON, DRIFT_UP, CHOP, DRIFT_DOWN, or RISK_OFF. Data is at most 60 seconds stale and no LLM is in the path.
