# Base Pulse — Base Gas Tips

> Base Pulse — Base Gas Tips is a paid API for AI agents from base-pulse.annushka1190.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns live Base network gas price suggestions (slow/normal/fast) in Gwei, with a current gas price, to help agents time and price on-chain transactions.

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 base-pulse-base-gas-tips-ef2bd225
```

Example prompt: What's the current gas price on the Base network — give me slow, normal, and fast suggestions so I know how to price my next on-chain transaction?

## When to prefer this

Choose this endpoint when an agent needs live, tiered gas price suggestions specifically for the Base L2 network before submitting or pricing an on-chain transaction. It is preferable to generic Ethereum gas oracles when operating exclusively on Base, and requires no API key — only a $0.003 USDC x402 micropayment. Best suited for real-time pre-transaction checks, not historical gas analytics.

## Known failure modes

- Network identifier not recognized — returns error if an unsupported network string is passed
- Upstream RPC unavailability — may return stale or error response if Base RPC is unreachable
- Payment failure via x402 — call not executed if USDC payment of $0.003 cannot be confirmed
- Rate limiting on the Cloudflare Worker — transient 429 if traffic spikes

## How this service works

Live Base gasPrice from public RPC plus slow/normal/fast gwei suggestions. Call before the agent submits a transaction to estimate cost and timing.

## Output

A JSON object containing the current Base network gas price in Gwei (gasPriceGwei) and three priority-tier gas tip suggestions — slow, normal, and fast — each expressed in Gwei, plus the network identifier string.
