# x402-toolbox Chain Gas Price

> x402-toolbox Chain Gas Price is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Fetches the current gas price on a blockchain network via a pay-per-call x402 endpoint requiring USDC payment on Base.

## 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 x402-toolbox-chain-gas-price-e1277478
```

Example prompt: What's the current gas price on the blockchain right now? I need it before I send a transaction.

## When to prefer this

Choose this endpoint when you need a quick, no-signup gas price lookup and are already operating within an x402 micropayment context using USDC on Base. It is ideal for AI agents that need deterministic, pay-per-call access without API key management. Prefer alternatives if you need historical gas data, multi-chain aggregation, or free tier access.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or missing schema parameter — may return malformed or empty gas data
- Network or chain unavailable — endpoint may return error or timeout
- Rate limiting or worker overload on Cloudflare Workers — possible 503 response

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' boolean indicating success and a 'paid' boolean confirming the x402 micropayment was processed, along with the current gas price data for the queried blockchain network.
