}ValueAtlas API
Public JSON endpoints for the BTC/gold dataset. Responses include permissive CORS and are designed so paid tiers can add broader history and extra assets later.
Free Endpoints
| Method | Path | Notes |
|---|---|---|
| GET | /api/v1/today | Returns { date, gramsPerBtc, btcUsd, goldUsdPerOz }. |
| GET | /api/v1/history?limit=30 | Returns the last N days of data, clamped to 30 on the free tier. |
| OPTIONS | /api/v1/* | CORS preflight support for browser clients. |
Compatibility Endpoints
Older snapshots and metric endpoints remain available for backwards compatibility while the public API migrates to /api/v1.

}Future Tiers
Paid tiers can extend the same shape with longer history windows and additional assets such as silver, S&P 500, or oil. The current response structure keeps that door open without forcing a breaking change later.
For production, pair the free tier with Cloudflare rate limiting at 100 requests per day per IP.
