## 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-gas-tracker-151ea94b
```

Example prompt: What are the current gas prices on Ethereum right now? I want to know if it's a good time to send a transaction.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.001 USDC) per-call gas price lookup for a specific blockchain and are already operating in a crypto-native x402 payment context. It is well-suited for agents that need real-time gas data without subscribing to a larger data provider.

## Known failure modes

- Unsupported chain name returns an error or empty result
- Payment failure via x402 blocks the call
- Service unavailable due to Render.com cold start or downtime
- Missing or malformed 'chain' query parameter may return an error or default chain data

## 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 current gas price data for the specified blockchain chain, likely including metrics such as base fee, priority fee, and estimated transaction costs in gwei or native token units. Exact response schema is minimal per the crawled metadata.
