# ManyLives Onchain – Base Network Gas Fee Lookup

> ManyLives Onchain – Base Network Gas Fee Lookup is a paid API for AI agents from api.manylives.me, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Returns current gas fees and transfer costs on the Base network, including max fee, base fee, priority fee, and estimated ETH costs for standard and token transfers.

## 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 manylives-onchain-base-network-gas-fee-lookup-86e4ab4e
```

Example prompt: What are the current gas fees on Base right now — give me the base fee, priority fee, and how much a token transfer would cost in ETH, using gwei units.

## When to prefer this

Use this endpoint when your AI agent needs real-time, pay-per-call gas fee data specifically for the Base network (Ethereum L2), particularly in trading or DeFi workflows where you want to avoid subscription overhead and need on-chain-verifiable data context. Prefer over generic Ethereum gas APIs when targeting Base specifically.

## Known failure modes

- Base RPC node unavailable — upstream network error
- Invalid units parameter value returns error or defaults to gwei
- Rate limiting or payment failure if x402 micropayment is not properly handled

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

A JSON object containing the current Base network block number, max fee, base fee, and priority fee (in gwei or wei depending on the units parameter), plus estimated ETH costs for a standard ETH transfer and an ERC-20 token transfer.
