## 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 stablecoin-full-census-latest-day-sorted-by-market-cap-0e26a367
```

Example prompt: Pull up the full stablecoin census for today — I want every stablecoin ranked by market cap, and flag any that are depegged or have been terminated.

## When to prefer this

Use this endpoint when you need a broad, ranked snapshot of the entire stablecoin market in a single call — especially when you want to identify depegged or terminated coins across the full universe without querying individual coins. Prefer it over single-entity endpoints (like the stablecoin triangle endpoint) when the goal is market-wide surveillance, ranking, or screening rather than deep-dive analysis of one coin.

## Known failure modes

- Payment failure — x402 USDC payment not processed, returns 402 Payment Required
- Upstream data unavailable — census data not yet populated for the current day
- Service downtime on zeabur.app hosting — returns 5xx error
- Rate limiting or authentication issues — returns 4xx error

## How this service works

[BATCH+PROOF] Full stablecoin census, latest day, ranked by market cap; lifecycle flags terminated and depegged. Add ?verifiable=1 and every row carries _hash_core so you can recompute the hash offline without trusting us. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

## Output

An object containing a 'rows' array of stablecoin records (each with name, market cap, lifecycle/depeg status, and related fields) sorted by market cap descending for the latest day, plus a 'count' integer indicating the total number of stablecoins enumerated.
