## 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-9cf6a5fc
```

Example prompt: What's the current SOL price in Japanese yen — I need a cryptographically signed attestation I can verify, sourced from Japanese exchanges like bitbank and GMO?

## When to prefer this

Use this endpoint when you need a cryptographically verifiable SOL/JPY price sourced specifically from Japanese exchanges (bitbank, GMO), particularly for DeFi contracts, audit trails, or any use case where tamper-proof price provenance matters. Prefer over generic price APIs when the Ed25519 attestation is required for downstream verification or when JPY denomination is specifically needed.

## Known failure modes

- Payment not received — endpoint requires $0.01 USDC via x402 protocol; missing or failed payment results in 402 response
- Exchange data unavailable — if bitbank/GMO are unreachable, price may be stale or endpoint may error
- Invalid signature verification — consumer must hold correct public key to verify Ed25519 signature
- Rate limiting — excessive calls may be throttled

## How this service works

Real-time Solana price in JPY, aggregated from multiple exchanges — Ed25519 signed attestation

## Output

Returns a JSON object containing: the trading domain (SOLJPY), an Ed25519 public key, a canonical price string in the format 'v1|PRICE|SOLJPY|<price>|JPY|0|<sources>|median|<timestamp>|<nonce>', and an Ed25519 signature over that canonical string. The price is the median of bitbank and GMO exchange quotes. The attestation can be independently verified using the returned public key.
