## 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-crypto-daily-briefing-cardano-handover-sbi-coinhako-robinhood-46b755df
```

Example prompt: Fetch me the Tenjin article about Cardano's handover to outside teams, the SBI acquisition of Coinhako, and Robinhood Chain's early volume — the handle is 'last-day-in-crypto' and the slug is 'last-day-in-crypto-cardano-handover-sbi-coinhako-robinhood-chain'.

## When to prefer this

Use this endpoint when you need to retrieve this specific Tenjin article about the Cardano development handover, SBI/Coinhako acquisition, and Robinhood Chain volume. Prefer it over general crypto news APIs when you specifically want Tenjin's editorial perspective and are willing to pay the $0.05 USDC micropayment via x402 protocol.

## Known failure modes

- Article not found if slug or handle is incorrect (404)
- Payment failure if wallet has insufficient USDC balance
- Handle does not exist or is unclaimed
- Article may be behind a paywall requiring x402 micropayment of $0.05 USDC
- Network timeout on retrieval

## How this service works
