## 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 synthora-market-dominance-34f80a2e -d '<json body>'
```

Example prompt: What's the current state of the overall crypto market? I need BTC and ETH dominance, total market cap, and 24-hour volume to understand the macro picture before making portfolio decisions.

## When to prefer this

Use this endpoint when an AI agent needs macro-level crypto market context — e.g. BTC/ETH dominance, total market cap, global volume — rather than individual coin prices or order book data. Ideal for portfolio agents needing macro context before making allocation decisions. The free-tier (first 3 calls per wallet) and low per-call cost ($0.001 USDC) make it suitable for frequent polling in automated workflows.

## Known failure modes

- Upstream data source failure — no charge applied per service terms
- Invalid or missing wallet address header may exhaust free-tier tracking
- Rate limiting after free tier is exhausted without valid x402 payment
- Stale data if upstream provider has latency or outage
- Malformed POST body returns validation error
