## 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 agentfeed-stablecoin-flows-eb35599f
```

Example prompt: What's the current total stablecoin market cap, and how much has it changed over the last 7 and 30 days? I want to know if money is flowing into or out of crypto right now.

## When to prefer this

Choose this endpoint when you need a fast, single-call macro snapshot of stablecoin supply health — total market cap, recent directional flows (7d/30d), and a leaderboard of the top stablecoins. Prefer it over general crypto market APIs when the specific question is about stablecoin capital flows as a risk sentiment indicator, not individual token prices or DeFi yields.

## Known failure modes

- Payment not processed — 402 response if USDC payment is not attached or fails
- Upstream data source unavailable — stale or missing market cap data
- Empty top_stables array if data provider returns no ranked list
- Network timeout if the aggregation backend is slow

## How this service works

Stablecoin supply and flows: total stablecoin market cap with 7d and 30d deltas and the top stables by size — the macro risk-on / risk-off dial for crypto. Use when you need to answer: Is stablecoin supply growing or shrinking?

## Output

Returns a JSON object with: total stablecoin market cap in USD, the 7-day USD delta, the 30-day USD delta, an ordered list of top stablecoins by size, the data source label, and a tool identifier. Also includes a boolean confirming payment was processed.
