## 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-last-day-in-crypto-coldcard-warning-project-agora-kalshi-suit-95f17d1f
```

Example prompt: Can you fetch the Tenjin article about the Coinkite COLDCARD seed entropy warning, the BIS Project Agora results, the New York Kalshi lawsuit, and Circle's NYDFS trust charter — the one published under the handle 'last-day-in-crypto' with slug 'last-day-in-crypto-coldcard-warning-project-agora-kalshi-suit'?

## When to prefer this

Use this endpoint when you specifically need the full text of this particular Tenjin article covering the Coinkite COLDCARD entropy warning, BIS Project Agora results, the New York v. Kalshi lawsuit, or Circle's NYDFS trust charter. Prefer it over general web search when you want a structured, gated journalistic piece with guaranteed delivery via x402 micropayment, rather than scraping fragmented news sources.

## Known failure modes

- Payment not made or x402 challenge not satisfied — returns 402 Payment Required before article text is delivered
- Invalid or misspelled handle — endpoint returns 404 not found
- Invalid or misspelled slug — endpoint returns 404 not found
- Article not yet published or taken down — returns 404 or empty response
- Network or server error — returns 5xx

## How this service works

Coinkite warned on COLDCARD seed entropy, BIS published Project Agora real-value testing results, New York sued Kalshi, and Circle received an NYDFS trust charter.

## Output

Returns a JSON object containing the full paid article text, covering four stories: Coinkite's COLDCARD seed entropy security warning, BIS Project Agora real-value testing results, New York State's lawsuit against Kalshi, and Circle's receipt of an NYDFS trust charter — unlocked after the x402 micropayment of $0.05 USDC is settled.
