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 stablecoin-depeg-monitor-b69c1965 -d '<json body>'
```

Example prompt: Check USDT, USDC, DAI, and FRAX for depeg right now and alert me if any of them have moved more than 0.5% away from $1.00.

## When to prefer this

Use this endpoint when you need a lightweight, read-only, single-call check on stablecoin peg status without requiring API keys. It is ideal for pre-trade safety checks, DeFi risk dashboards, or scheduled depeg alarms via webhook. Prefer this over rolling your own price checks when you want dual-source validation (CoinGecko + Coinbase) in one call at low cost.

## Known failure modes

- Unrecognized stablecoin symbol or CoinGecko ID returns a lookup failure for that coin without charge
- Exceeding the 10-coin maximum per call returns a validation error
- Upstream CoinGecko or Coinbase data unavailability may cause stale or missing prices
- Invalid depegThresholdPct type (non-numeric) causes request rejection

## How this service works

Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.

## Output

Returns current prices for each requested stablecoin fetched from CoinGecko and cross-checked on Coinbase, along with each coin's deviation from $1.00, its peg state classification, and a depeg alert flag for any coin crossing the configured threshold. Failed lookups are not charged.
