> Mangrove DeFi Stablecoin Metrics is a paid API for AI agents from api.mangrovedeveloper.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-04).

Fetches global stablecoin supply metrics including top stablecoins by market cap, total supply in USD, stablecoin count, and supply broken down by blockchain chain.

## 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 mangrove-defi-stablecoin-metrics-4a068cca
```

Example prompt: What's the current total stablecoin supply across all blockchains, and how does it break down by chain like Ethereum, Tron, and Solana? Also show me the top stablecoins by supply.

## When to prefer this

Use this endpoint when you need a comprehensive, aggregated view of the global stablecoin market sourced from DeFiLlama, including cross-chain supply distribution and top stablecoin rankings. Prefer this over manual chain queries when you need a single call to get the full stablecoin landscape across Ethereum, Tron, Solana, BSC, Base, and other major chains simultaneously.

## Known failure modes

- Upstream DeFiLlama data unavailable — returns error or stale data
- Malformed query parameters may return 400 Bad Request
- Payment not completed — 402 Payment Required if x402 payment header is missing or invalid
- Rate limiting if too many requests are made in a short window
