Embed live peg-health signals anywhere

A single line of HTML gives your site, README, or research note a live, color-coded badge that reflects the current depeg severity of any tracked stablecoin. The signal is composite (CoinGecko spot + Chainlink USD oracle + issuer-side stress) and updates every 5 minutes — your page never goes stale. Same data behind every badge is available as JSON. Free, no key, CORS-open.

JSON API

Three endpoints, one signal

All endpoints return CORS-open JSON or SVG with public CDN caching. The same composite score that drives vaultscanner.xyz.

GET/api/depeg

List every tracked stable. Use when you want to render many at once or build a leaderboard.

curl https://vaultscanner.xyz/api/depeg
GET/api/depeg/[asset]

Single asset's full DepegSignal — spot, oracle, divergence, severity, vault-health subscore, sources, fetchedAt. Case-insensitive.

curl https://vaultscanner.xyz/api/depeg/USDC
GET/api/depeg/[asset]/badge

A shields.io-style SVG badge for the asset's current severity. Drop in an <img> tag.

GET/methodology

How the composite score is computed. Read this before embedding so you can defend the number when someone asks where it came from.

Cache & limits

What to expect at scale

The constraints you should plan around if you're integrating against the API.

Cache window: 5 minutes at the edge (s-maxage=300, stale-while-revalidate=600). Identical requests within that window hit Vercel's CDN, not our function. Repeated polling faster than every 5 min is wasted — the underlying CoinGecko + Chainlink data only refreshes that often.

Rate limit: 60 requests per IP per minute on /api/depeg/*. Exceeding it returns a 429 with a Retry-After header. Every response includes x-ratelimit-remaining so you can self-throttle.

CORS: wide-open (access-control-allow-origin: *). Call directly from the browser without a proxy.

Stability: response shapes are unversioned today; consider this a developer preview. We won't silently break things, but if we need to change the shape we'll move to /api/v1/ and keep the current paths working for a deprecation window.

Attribution: not required, but a backlink to vaultscanner.xyz is appreciated. Each badge already deep-links into the Depeg Lab on click.
