## 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 trusted-information-api-crypto-market-context-8d9202f2
```

Example prompt: What's the current market context for BTC-USD — give me the price, whether it's in an uptrend or downtrend, the 14-day range, and the realized volatility regime.

## When to prefer this

Choose this endpoint when you need structured, quantitative crypto market context — especially volatility regime, trend state, and statistical price bands — for a specific asset pair, without needing to set up an API key or account. Ideal for AI agents making pay-per-call requests in USDC via x402, and for use cases requiring UK-hosted, no-signup data access for BTC, ETH, or other major pairs.

## Known failure modes

- Missing or invalid 'pair' query parameter returns an error
- Unsupported pair (e.g. obscure altcoin not on Binance) may return empty or error response
- Payment not completed (HTTP 402) if USDC micropayment via x402 protocol fails
- Rate limiting or upstream Binance data outage may cause stale or unavailable data
- Malformed pair format (e.g. 'BTCUSD' instead of 'BTC-USD') may return error

## How this service works

Pay-per-call UK company, property and crypto market data for AI agents via x402. Official sources, no signup, no API keys, failed calls never charged.

## Output

A JSON object containing the asset pair, current price, timestamp, 20-day SMA and trend state (uptrend/downtrend/sideways), price-vs-SMA percentage, 14-day high/low range and position, realized daily and annualized volatility with regime classification and 90-day percentile, and the expected 1-sigma daily price band (lower and upper bounds). Data sourced from Binance.
