Technical details
Endpoint
POSThttps://bbx-stocks.vercel.app/api/forex/rate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, programmatic lookup of a live forex exchange rate for a specific currency pair, especially within an x402 micropayment-enabled agent workflow where per-call billing at ~$0.065 is acceptable. Suitable for spot rate lookups rather than historical data or bulk batch conversions.
Side effects
- Invalid or unsupported currency code returns an error response
- Payment failure or insufficient USDC balance prevents API access
- Rate limiting or quota exceeded errors
- Network timeout if upstream forex data provider is unavailable
- Malformed request body returns 400-level error
