# Market Intelligence API – Stablecoin Peg Monitor

> Market Intelligence API – Stablecoin Peg Monitor is a paid API for AI agents from api.marketintelligenceapi.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-20).

Returns real-time peg status, DEX depth, and Chainlink price data for major stablecoins (USDT, DAI, USDS, USDe, PYUSD, GHO, crvUSD, RLUSD, USD1, FDUSD, USDC) with a categorical health status.

## Facts

- Endpoint: GET https://api.marketintelligenceapi.com/api/v1/markets/stablecoins?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402

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 market-intelligence-api-stablecoin-peg-monitor-41411abc
```

Example prompt: Before I route this payment through USDT, check the current peg status and DEX depth for all major stablecoins so I know if any are showing depeg risk or thin liquidity right now.

## When to prefer this

Use this endpoint when you need to verify stablecoin peg health before routing payments, executing DeFi trades, or holding stablecoin positions — particularly when on-chain DEX depth and oracle divergence matter. Prefer this over generic price feeds when you need both a categorical peg status and liquidity depth signal in a single call. Best suited for automated agents making pre-trade or pre-payment risk checks across the major Ethereum stablecoins.

## Known failure modes

- Stale data if cache has not refreshed within 5-minute window
- Missing coverage for newer or less liquid stablecoins not in the supported list
- API unavailability causing inability to retrieve peg status before time-sensitive transactions
- Payment failure (x402) if USDC balance is insufficient for the $0.002 per-call fee

## How this service works

Stablecoin peg monitor and depeg alerts ($0.005): peg of USDT, USDC, DAI, USDS, USDe, PYUSD, GHO, crvUSD, RLUSD, USD1 and FDUSD from Ethereum DEX prices, depth ($100k sale impact) and Chainlink, with a status (PEGGED, WATCH, DEPEG, THIN_MARKET). Refreshed every 5 minutes. Use before holding or routing through a stablecoin.

## Output

Returns peg status (PEGGED, WATCH, DEPEG, or THIN_MARKET) for each covered stablecoin (USDT, DAI, USDS, USDe, PYUSD, GHO, crvUSD, RLUSD, USD1, FDUSD, USDC), along with the current Ethereum DEX price, Chainlink oracle price, and the price impact of a $100k sale — refreshed every 5 minutes.
