## 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-blog-eth-r-d-weekly-frame-transactions-enter-the-fixture-phase-d4d171a8
```

Example prompt: Fetch me the full tenjin.blog article by eth-rd on frame transactions entering the fixture phase — the one covering EIP-8141, EIP-8250, and EIP-8272 byte-level rules for payload shape, signing, gas, and opcodes.

## When to prefer this

Use this endpoint when you specifically need the full text of tenjin.blog's ETH R&D Weekly article on frame transactions entering the fixture phase (EIP-8141/8250/8272), and are prepared to fulfill the x402 micropayment. Prefer this over general web search when you need structured, authenticated article JSON from a pay-per-read publisher rather than a cached snippet.

## Known failure modes

- Payment not provided or invalid x402 challenge response → 402 Payment Required
- Wrong handle or slug → 404 Not Found
- Article not yet published → 404 or empty result
- Handle 'latest' used instead of wallet address for durable alias → not payable / unresolvable
- Network timeout → 5xx error

## How this service works

EIP-8141, EIP-8250, and EIP-8272 spent the week turning frame-transaction prose into byte-level rules for payload shape, signing projection, charged gas, refunds, approval scope, and opcode assignments.

## Output

A JSON object containing the full text of the article detailing how EIP-8141, EIP-8250, and EIP-8272 translate frame-transaction prose into byte-level specifications — covering payload shape, signing projection, gas charging, refunds, approval scope, and opcode assignments — gated behind a $0.10 USDC x402 payment.
