## 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 api-myceliasignal-com-496d47f4
```

Example prompt: Show me all currently available SOL options instruments — I need the full list of strikes and expiries with a signed attestation so I can verify the data is authentic.

## When to prefer this

Use this endpoint when you need to discover what SOL options instruments exist before querying Greeks or pricing data. It is the discovery layer for SOL options — use it first to get valid instrument identifiers, then pass those to pricing/Greeks endpoints. Prefer this over ETH or BTC equivalents when specifically working with Solana derivatives.

## Known failure modes

- No SOL options instruments currently available — empty result set returned
- Payment of $0.03 USDC not processed — 402 Payment Required response
- Ed25519 signature verification failure — attestation invalid
- Exchange data feed unavailable — instruments list may be stale or incomplete
- Rate limit exceeded — too many requests in a short period
