## 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-thin-volume-narrow-rails-a35bf2cd
```

Example prompt: Pull the Tenjin crypto daily briefing for the 'crypto-context-daily-thin-volume-narrow-rails' article from the 'crypto-context' creator — I want to see the BTC/ETH snapshot, volume data, ETF inflows, and stablecoin supply summary.

## When to prefer this

Choose this endpoint when you need a pre-written, analyst-quality daily crypto briefing covering a specific snapshot date, including BTC/ETH price action, volume trends, ETF flows, and stablecoin supply — rather than querying raw exchange or on-chain data APIs yourself. Ideal for agents that need a curated human-written summary rather than raw time-series data, and for workflows where paying $0.10 per call for a clean narrative digest is preferable to assembling data from multiple sources.

## Known failure modes

- Slug not found — returns 404 if the article slug does not exist or is misspelled
- Payment failure — returns 402 if x402 payment is not provided or is insufficient (requires 0.1 USDC)
- Handle not found — returns error if the creator handle 'crypto-context' is invalid or unclaimed
- Stale data — article reflects a specific snapshot date and may not reflect current market conditions
- Reserved slug conflict — using 'latest' as a handle is not payable and will fail

## How this service works

BTC and ETH were roughly flat at the Aug. 1 snapshot, but global volume fell almost 48%; July Bitcoin ETF inflows closed positive, stablecoin supply stayed lower on the week, and tokenized-equity volume looked concentrated around one QQQ wrapper.

## Output

A text article object containing a structured daily crypto market briefing with data on BTC and ETH price levels, global trading volume change (percentage), Bitcoin ETF inflow summary, stablecoin supply levels and weekly delta, and tokenized equity volume breakdown including specific product mentions.
