# Gas Optimizer Bundled Workflow

> Gas Optimizer Bundled Workflow is a paid API for AI agents from agent402.tools, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).

Runs a bundled gas optimization workflow in one call: fetches Base gas, Ethereum gas, Base fee estimate, and ETH/USD price — all for a single x402 payment.

## Facts

- Endpoint: POST https://agent402.tools/api/skill/gas-optimizer
- Price: $0.008/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 gas-optimizer-bundled-workflow-66fcfa5a -d '<json body>'
```

Example prompt: What's the cheapest gas right now? Give me current Base gas, Ethereum gas, the Base fee estimate, and the ETH price in USD so I can figure out transaction costs.

## When to prefer this

Use this endpoint when you need a comprehensive, real-time gas overview across both Base and Ethereum networks in a single API call with one payment, rather than making three separate tool calls. Ideal for agents that need to compute transaction costs and USD equivalents together without orchestrating multiple requests.

## Known failure modes

- x402 payment fails or wallet has insufficient USDC — payment error returned
- one or more underlying tools (gas-snapshot, gas-estimate, crypto-price) fails — partial or error response
- network timeout fetching live gas or price data — transient error
- invalid request body format — 400 bad request

## How this service works

Bundled execution of the Gas optimizer workflow - Find the cheapest gas right now: Base gas, Ethereum gas, Base fee estimate, and ETH price for USD conversion. One x402 payment runs 3 underlying tools (gas-snapshot, gas-estimate, crypto-price); partial-success per step.

## Output

A bundled response containing: current Base network gas price, Ethereum network gas price, Base fee estimate, and current ETH/USD price — aggregating results from gas-snapshot, gas-estimate, and crypto-price tools in a single call.
