## 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-hegota-pfi-list-article-3699ec31
```

Example prompt: Fetch the Tenjin ETH R&D daily article about Hegota's PFI list and the Glamsterdam testnet Plataberget proposal for the slug eth-r-d-daily-hegota-s-pfi-list-starts-moving under the eth-rd creator handle.

## When to prefer this

Choose this endpoint when you need the specific Tenjin ETH R&D daily article covering Hegota PFI list movement, Plataberget testnet proposal, and EIP-8297 tree semantics. Prefer it over general Ethereum news aggregators when you want Tenjin's curated, paid research-grade write-up of core Ethereum developer activity keyed to a specific article slug.

## Known failure modes

- Payment not provided or rejected — x402 payment required before content is returned
- Invalid or missing handle — 404 if creator handle does not exist
- Invalid or missing slug — 404 if article slug not found under that handle
- Slug 'latest' used with handle instead of wallet address — not payable, returns error
- Network timeout or upstream blog unavailability

## How this service works

EIP-8081 added four Hegota PFI entries after ACDE #242, Plataberget was proposed as a public Glamsterdam testnet, and EIP-8297 moved toward zero-means-absent tree semantics.

## Output

Returns the full article content from Tenjin covering Ethereum R&D daily developments including EIP-8081 Hegota PFI list updates, the Plataberget Glamsterdam testnet proposal, and EIP-8297 zero-means-absent PBT tree semantics, as a paid read requiring 0.1 USDC via x402.
