## 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 defillama-stablecoin-market-cap-by-chain-60c91bbb
```

Example prompt: Which blockchain currently has the highest total stablecoin circulating supply, and how does it compare to Ethereum, Solana, and Tron? Pull the latest data from DefiLlama's stablecoin chain breakdown.

## When to prefer this

Use this endpoint when you need a snapshot of total stablecoin circulating supply per chain — ideal for cross-chain comparisons, DeFi market analysis, or monitoring stablecoin liquidity distribution. Prefer this over the historical stablecoin endpoint when you need current data only, and over the stablecoin detail endpoint when you want an aggregate view across all stablecoins rather than a single asset.

## Known failure modes

- Payment not completed — endpoint returns 402 if x402 payment header is missing or invalid
- DefiLlama upstream unavailable — may return 503 or timeout if DefiLlama API is down
- Empty or stale data — DefiLlama may return incomplete chain data during indexing gaps
- Rate limiting — repeated calls without valid payment may be rejected
