## 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 chainanalyzer-stablecoin-issuer-supply-d3724129
```

Example prompt: Pull the current stablecoin supply data for the USDC issuer — I need total and circulating supply broken down by chain, plus the cumulative mint and burn totals and the most recent 20 issuance and redemption events with their transaction hashes.

## When to prefer this

Use this endpoint when you need structured, agent-ready stablecoin supply data for a specific issuer without scraping the public UI. It is the right choice when you need per-chain supply breakdowns, mint/burn totals, and recent issuance event history with transaction hashes in a single call. Prefer this over generic blockchain explorers when you want normalized cross-chain data for a named stablecoin issuer.

## Known failure modes

- Unknown or invalid slug returns an error or empty result
- Slug spelling mismatches (e.g. wrong casing or hyphenation) cause not-found errors
- Rate limiting or payment failure at $0.05 USDC per call if x402 payment header is missing or invalid
- Stale data if the issuer has very recent on-chain activity not yet indexed
- Network timeouts for chains with slow indexing pipelines

## How this service works

Stablecoin issuer supply in one JSON call: pass the issuer as the `slug` query parameter. Returns total and circulating supply per chain, cumulative mint and burn totals, and the 20 most recent issuance / redemption events with transaction hashes. Same numbers as the public issuer page, shaped for agents.

## Output

A JSON object containing total and circulating supply figures broken down per chain, cumulative lifetime mint and burn totals, and an array of the 20 most recent issuance and redemption events each with transaction hash, amount, chain, and event type.
