## 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 logicnodes-gas-price-forecast-894826d7 -d '<json body>'
```

Example prompt: What are the forecasted gas prices on Ethereum mainnet for the next few hours so I can decide when to submit my transaction?

## When to prefer this

Choose this endpoint when an agent needs forward-looking gas price intelligence rather than just current gas prices — ideal for scheduling transactions, optimizing DeFi execution, or budgeting multi-step workflows across EVM chains or Aptos. Prefer LogicNodes over generic RPC gas queries when a probabilistic forecast (not just a spot price) is needed, and when paying per-call via USDC x402 is acceptable.

## Known failure modes

- Unsupported chain ID returns an error indicating the network is not covered
- Malformed request body returns a 400-level error with validation details
- Payment not included or insufficient USDC results in 402 Payment Required response
- Network congestion or upstream node outage may cause delayed or unavailable forecast data
- Rate limit exceeded on free tier returns a 429 error

## How this service works

Exact answers for AI agents: 40+ tools for EVM chains and Aptos, gas on 14 chains, never a guess. Free tier; pay per call in USDC (x402) on 13 networks.

## Output

Returns a forward-looking gas price forecast for the requested EVM chain or Aptos, including predicted fee levels (e.g., base fee, priority fee) over a time horizon, enabling agents to choose optimal transaction submission windows and estimate costs accurately.
