## 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 crypto-agent-brief-api-5a3aa158
```

Example prompt: Can you get me an LLM-ready brief on Bitcoin — including the current price and technical analysis — and format it as markdown?

## When to prefer this

Choose this endpoint when you need a compact, LLM-ready crypto brief that blends price data with technical analysis or trending rankings in a single call — especially in agent workflows where a micropayment model (0.01 USDC via x402) is acceptable and you want pre-summarized, actionable output rather than raw exchange data.

## Known failure modes

- Missing required 'q' parameter returns an error response
- Unrecognized or misspelled coin name may return empty or fallback data
- Payment not fulfilled (402) if x402 micropayment of 0.01 USDC on Base is not completed
- Upstream price data source outage causing stale or unavailable data
- Rate limiting or service unavailability on railway.app hosting

## How this service works

x402 pay-per-call crypto trading intelligence for AI agents. Get live Bitcoin/ETH/SOL BUY/SELL/HOLD signals with support/resistance, volatility regime, risk, edge_score and invalidation — not raw CoinGecko dumps. Price: 0.01 USDC on Base per call. Best value: compare up to 5 coins + vs-BTC strength in one payment. Free routes use security: []. Paid routes require x402 (PAYMENT-SIGNATURE / X-PAYMENT) after HTTP 402. Free tease: GET /api/preview?q=btc (price only). Docs: /llms.txt.

## Output

A structured, LLM-ready text brief containing requested crypto data such as current price, technical analysis indicators, trend signals, and/or comparative metrics for one or more cryptocurrencies, optionally formatted per the format parameter.
