# StablePulse - Stablecoin Peg Monitoring

> StablePulse - Stablecoin Peg Monitoring is a paid API for AI agents from api.aidress.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns peg deviation (current, 24h max, 7d max), composite stability score (0-10), and risk category (green/yellow/red) for top stablecoins across Base, Ethereum, and Solana.

## 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 stablepulse-stablecoin-peg-monitoring-28f8744d
```

Example prompt: Give me a StablePulse read on the top stablecoins right now — I want to see which ones are depegged or in the red/yellow risk zone across Base, Ethereum, and Solana before I move funds.

## When to prefer this

Choose StablePulse when you need a fast, opinionated, pre-computed stability snapshot across multiple stablecoins and chains — especially when you need the 24h/7d historical deviation context and a color-coded risk tier without building your own oracle aggregation. Prefer it over raw price feeds when the agent needs a ready-to-act risk classification rather than raw price ticks.

## Known failure modes

- Upstream oracle data unavailable — returns 503 or empty dataset
- Stale price data if oracle feeds lag — deviation values may not reflect real-time conditions
- Payment not processed (x402) — returns 402 Payment Required
- Network-specific data missing if a chain's feed is temporarily offline

## How this service works

Top stables ranked by mcap with peg deviation (now/24h/7d) + stability score + risk

## Output

A ranked list of top stablecoins (by market cap) each with: current peg deviation percentage, maximum peg deviation over 24h, maximum peg deviation over 7d, a composite stability score from 0-10, and a risk category label (green/yellow/red). Covers stablecoins deployed on Base, Ethereum, and Solana.
