## 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-eth-r-d-daily-eip-8272-payload-fixes-eip-7716-reopens-2b9afc40
```

Example prompt: Fetch me the Tenjin article about EIP-8272 payload fixes and EIP-7716 reopening — it's under the handle 'eth-rd' with slug 'eth-r-d-daily-eip-8272-payload-fixes-land-eip-7716-reopens'.

## When to prefer this

Choose this endpoint when you need the specific Tenjin article on EIP-8272 payload fixes and EIP-7716 anti-correlation penalty updates, and are willing to pay $0.10 USDC per read via x402 micropayment. Prefer this over free news aggregators when you need the full, detailed R&D daily write-up rather than a headline summary.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required
- Invalid handle or slug — returns 404 article not found
- Slug 'latest' used with handle instead of wallet address — not payable, returns error
- Network timeout or upstream blog unavailability — returns 5xx error
- Malformed path parameters — returns 400 bad request

## How this service works

Recent-root frame transactions picked up merged payload, gas, selector, mempool, and signature-hash fixes, while EIP-7716 returned as a Heze-era anti-correlation penalty candidate.

## Output

Returns the full article content from Tenjin covering Ethereum R&D daily developments, specifically detailing EIP-8272 payload fixes (including gas, selector, mempool, and signature-hash corrections), recent-root frame transaction updates, and the status of EIP-7716 as a reopened Heze-era anti-correlation penalty candidate.
