## 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-context-daily-flat-tape-busier-dollar-rails-e63bb5e8
```

Example prompt: Pull the Tenjin daily crypto context article 'crypto-context-daily-flat-tape-busier-dollar-rails' from the handle 'crypto-context' — I want the BTC price, market cap change, sentiment reading, and any major news like the Mastercard BVNK story.

## When to prefer this

Choose this endpoint when you need a pre-packaged, narrative crypto market context briefing for a specific date including BTC price, sentiment index, stablecoin float, and curated news — rather than building a raw data pipeline from multiple price or volume APIs. Ideal for agents that need human-readable yet structured crypto summaries with source-linked context.

## Known failure modes

- Slug not found — article does not exist at the given path, returns 404
- Payment failure — insufficient USDC balance or x402 payment protocol error
- Handle mismatch — wrong creator handle returns no content
- Rate limiting — too many requests in a short window
- Stale content — article may reflect data from a specific past date rather than live market data

## How this service works

BTC held near $64,097 and total market cap ticked up 0.12%, but sentiment fell to Extreme Fear, global volume slipped, weekly stablecoin float stayed lower, and Mastercard closed BVNK.

## Output

A structured article payload containing crypto market data points (BTC price ~$64,097, total market cap change +0.12%, Extreme Fear sentiment, slipped global volume, weekly stablecoin float comparison) and curated news items such as Mastercard closing BVNK, delivered as a JSON object with type and example fields.
