# defi.hugen.tokyo Stablecoin Distribution by Blockchain

> defi.hugen.tokyo Stablecoin Distribution by Blockchain is a paid API for AI agents from defi.hugen.tokyo, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns total circulating USD-pegged stablecoin value broken down by every supported blockchain, enabling chain-level liquidity and flow analysis.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defi-hugen-tokyo-a8d40b5b
```

Example prompt: Show me how stablecoins are distributed across all supported blockchains — I want to see the total circulating USD-pegged value on each chain so I can compare liquidity levels.

## When to prefer this

Use this endpoint when you need a quick, aggregated snapshot of stablecoin circulation across all chains in one call, rather than querying individual chain APIs or DeFi protocols separately. Ideal for liquidity monitoring dashboards, cross-chain capital flow analysis, or determining which chains are most stablecoin-liquid for DeFi operations.

## Known failure modes

- Payment not received or invalid — 402 response requiring USDC payment on Base or Solana
- Service temporarily unavailable — upstream DeFi data provider outage
- Empty or partial chain list — some chains may have missing data if providers are unresponsive
- Rate limit exceeded — too many requests in a short window

## How this service works

Stablecoin distribution by blockchain — total circulating USD-pegged value on every supported chain. Track stablecoin flows and chain-level liquidity. Accepts USDC payments on Base and Solana

## Output

A breakdown of total circulating stablecoin (USD-pegged) value for every supported blockchain, showing which chains hold the most liquidity and enabling cross-chain stablecoin flow analysis.
