## 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 lazareus-get-recommended-priority-fee-for-base-a92820cf
```

Example prompt: What's the recommended priority fee I should use right now for a transaction on Base so it confirms quickly?

## When to prefer this

Use this endpoint when you need a real-time, pay-per-call priority fee recommendation specifically for the Base (Ethereum L2) network without requiring an account or subscription. Prefer this over generic gas estimation libraries when building autonomous agents that need fresh on-chain fee data on demand, especially in x402-payment-capable pipelines.

## Known failure modes

- Network connectivity issues with Base RPC nodes returning stale or unavailable data
- Payment failure via x402 resulting in 402 response before data is returned
- Base network congestion may cause fee estimates to change rapidly, making recommendations stale within seconds
- Malformed or missing response if Base node data is temporarily unavailable

## How this service works

Lazareus gives AI agents pay-per-call S3-compatible storage, plus real-time network health scores and priority fee recommendations across Solana, Base, and Ethereum. No account, no subscription — paid per call via x402.

## Output

Returns a recommended priority fee (likely in gwei or wei) that an agent or user should set on their Base network transaction to achieve timely confirmation, based on real-time network conditions.
