## 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 tenjin-eip-8141-mempool-lifecycle-daily-brief-fbb30777
```

Example prompt: Fetch me the Tenjin daily article on EIP-8141's mempool lifecycle — the one covering replacement, eviction, payer exposure, transaction logs, and the canonical paymaster implementation from the eth-rd feed.

## When to prefer this

Use this endpoint when you need the specific Tenjin daily research article on EIP-8141 mempool lifecycle PRs and Ethereum R&D updates, especially when the user needs structured insight into new EIP-8141 PRs, execution-specs devnet fixtures, or canonical paymaster details. Prefer this over general web search when you need reliable, paywalled, researcher-curated Ethereum protocol content from the Tenjin platform.

## Known failure modes

- Payment not completed — returns 402 if x402 payment of 0.1 USDC is not fulfilled
- Invalid slug — returns error if the slug does not match a published article
- Invalid or unclaimed handle — returns error if the creator handle is not recognized
- Article not found — 404 if the slug has been unpublished or removed
- Network timeout — slow response if upstream content service is unavailable

## How this service works

EIP-8141's new PRs define replacement, eviction, payer exposure, transaction logs, unrolled-batch log rollback, the signature scheme registry, and the canonical paymaster implementation. execution-specs also merged a devnet-driven Amsterdam receipt-status fixture after a nimbus top-frame OOG mismatch.

## Output

The full content of the Tenjin daily research article, including structured summaries of EIP-8141's new PRs (replacement, eviction, payer exposure, transaction logs, unrolled-batch log rollback, signature scheme registry, canonical paymaster implementation) and execution-specs updates including the Amsterdam receipt-status fixture and the nimbus top-frame OOG mismatch.
