## 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 mycelia-signal-btc-usd-swing-pivot-support-resistance-levels-4cb7951e
```

Example prompt: Pull the current BTC/USD swing-pivot levels — I want to see which price zones have acted as support or resistance over the past 69 days, along with their strength and how close the current price is to each level, and make sure the data is cryptographically signed.

## When to prefer this

Choose this endpoint when you need a deterministic, cryptographically attested snapshot of BTC/USD price structure — specifically historical swing-pivot levels — rather than a forward-looking price prediction or a real-time order book view. Ideal for agents that require verifiable, auditable market structure data for risk management, options pricing, or trade entry decisions. Prefer over unattested price feeds when tamper-evidence is required.

## Known failure modes

- Payment not provided or insufficient (x402 payment required, $0.15 USDC per call)
- Upstream price data unavailable or stale, resulting in an error or degraded response
- Invalid or malformed request parameters causing a 400 error
- Signature verification failure if the consumer's Ed25519 public key validation logic has a bug
