## 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-pbt-zeroization-becomes-deletion-1d5da7ca
```

Example prompt: Fetch me the full text of the Tenjin ETH R&D daily piece about PBT zeroization becoming deletion — the one covering EIP-8297, EIP-8347, EIP-7668, and EIP-8038 access-list costs — using handle 'eth-rd' and slug 'eth-r-d-daily-pbt-zeroization-becomes-deletion'.

## When to prefer this

Use this endpoint when you specifically need the full text of this Tenjin ETH R&D daily briefing article on PBT zeroization, EIP-8347, EIP-7668, and EIP-8038 — particularly when an agent needs to programmatically pay-per-read independent Ethereum protocol research content via the x402 micropayment standard.

## Known failure modes

- Payment not processed or x402 challenge not met — article content withheld, returns payment-required response
- Invalid handle or slug — returns not found error
- Slug 'latest' used without wallet address form — not payable, returns error
- Network or server error — returns 5xx status

## How this service works

EIP-8297 now treats zero values as absent in the partitioned binary tree, EIP-8347 adds the offline migration path, EIP-7668 entered Hegota PFI, and EIP-8038 access-list costs moved to 2900.

## Output

Full text JSON of the pay-per-read article covering Ethereum R&D updates: EIP-8297 (PBT zero-value zeroization treated as deletion), EIP-8347 (offline migration path addition), EIP-7668 (Hegota PFI entry), and EIP-8038 (access-list costs moved to 2900), delivered after x402 micropayment of $0.10 USDC is processed.
