# Beggar Bot Stablecoin Depeg Monitor (Base Mainnet)

> Beggar Bot Stablecoin Depeg Monitor (Base Mainnet) is a paid API for AI agents from beggar-bot-demand.beggarbot.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).

Returns a list of stablecoins on Base mainnet that are currently depegged beyond a configurable deviation threshold, filtered by minimum circulating supply.

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 beggar-bot-stablecoin-depeg-monitor-base-mainnet-064881c0
```

Example prompt: Are any stablecoins on Base mainnet currently depegged by more than 2%? Only show me ones with at least $5 million in circulation, and limit results to the top 10.

## When to prefer this

Use this endpoint when you need a live, on-chain scan of stablecoins currently depegged on Base mainnet, particularly when you want to filter by deviation severity and supply size. Prefer this over general DeFi APIs when you need Base-specific stablecoin health data with configurable thresholds and are already operating within the x402 micropayment flow on Base.

## Known failure modes

- Payment not received — x402 payment of $0.02 USDC on Base mainnet required before data is returned
- Invalid query parameter types — threshold_pct or min_circulating passed as non-numeric strings
- No results returned — no stablecoins currently exceed the specified threshold or supply filter
- Rate limiting or worker timeout on Cloudflare edge
- Network parameter set to unsupported value other than base-sepolia

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

A JSON list of stablecoins on Base mainnet that are currently trading off their intended peg, each entry including the token name/symbol, contract address, current deviation percentage, and circulating supply — filtered by the requested threshold and supply minimum, up to the requested row limit.
