## 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 scriptmasterlabs-eth-price-api-8063bdc3
```

Example prompt: What's the current price of ETH right now? Pull it from the ScriptMasterLabs x402 data feed — I need the live spot price.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call ETH spot price lookup settled in USDC on Base via the x402 micropayment protocol, especially in agentic workflows where you want to avoid API key management and pay only for what you use. It is well-suited for AI agents with x402-compatible wallets needing real-time Ethereum price data at very low cost ($0.001 per call).

## Known failure modes

- Payment not settled — 402 response if USDC payment on Base is not attached or insufficient
- Service unavailable on Render free-tier cold start — slow or timed-out response
- Stale or cached price if upstream price feed is delayed
- Empty or malformed response body if upstream data provider is down
- Rate limiting or quota errors if too many requests are sent

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns the current market price of Ethereum (ETH), likely expressed in USD. Response structure is minimal per the schema; expect a numeric price value or JSON object containing ETH price data at time of call.
