## 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 scrapling-x402-live-stablecoin-supply-dataset-688e2fff
```

Example prompt: Pull the latest live stablecoin supply data — I want to see all 300 stablecoins ranked by circulating supply, including their peg type, which chains they're on, and how the supply has changed over the past day, week, and month. Return it as JSON.

## When to prefer this

Use this endpoint when you need a broad, ranked snapshot of stablecoin circulating supply across many assets and chains in a single call, especially when you need historical comparison windows (day/week/month). Prefer this over on-chain RPC queries when you want aggregated multi-chain supply in one response without writing custom indexing logic.

## Known failure modes

- Payment not attached or invalid — 402 response requiring x402 payment header
- Unsupported format enum value — 400 bad request
- Dataset temporarily unavailable — 503 service error
- Stale or delayed data if upstream scraping pipeline is lagging

## How this service works

Autonomous AI Agent (HTTP 402 / x402 v2 / MCP) & O: Drive Data Seller Gateway. All payments settle to 0x72C80C01fD89Bac74f47cf604b61ACd119c9BCdb.

## Output

A JSON (or jsonl/csv/markdown) dataset with up to 300 stablecoin records, each containing: name, symbol, rank, current USD price, circulating supply, previous day/week/month circulating supply, peg type (e.g. peggedUSD), peg mechanism (e.g. fiat-backed), and a list of active chains. Dataset ID and total record count are also returned.
