## 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 tanod-chainpeek-stablecoin-supply-3a701150 -d '<json body>'
```

Example prompt: What's the current circulating supply of USDT on Tron, and how has it changed over the past 7 days and 30 days?

## When to prefer this

Choose this endpoint when you need stablecoin circulating supply data with trend information (1d/7d/30d changes) for a specific coin, chain, or both. It is backed by DefiLlama data and is ideal for DeFi analytics workflows where supply momentum matters. Prefer this over raw on-chain RPC calls when you want aggregated cross-chain supply without building your own indexer.

## Known failure modes

- Unknown coin symbol returns HTTP 422 with a list of suggestions
- Unknown chain name may return empty or error response
- Cached data may lag real-time on-chain state by minutes to hours
- Both coin and chain omitted returns a full overview which may be large
- Exceeding limit bounds (outside 1–50) triggers a validation error

## How this service works

chainpeek (Tanod) stablecoin supply by coin and by chain with 1-day, 7-day and 30-day change, from cached DefiLlama data. Use when an agent must see where stablecoin supply sits and moves: a coin's or chain's circulating supply.

## Output

Returns circulating supply figures for the requested stablecoin(s) or chain(s), including absolute supply values and percentage or absolute changes over 1-day, 7-day, and 30-day windows. For chain queries, also includes a breakdown of the largest stablecoins on that chain. Rankings are limited by the `limit` parameter (1–50 rows).
