Technical details
Endpoint
POSThttps://x402-trading-hub.vercel.app/api/forex/rate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time forex exchange rate between two currency pairs and can pay per-call in USDC on Base via the x402 protocol. Prefer this over free rate APIs when freshness, reliability across multiple data providers, and programmatic micropayment access matter.
Side effects
- Missing required 'from' or 'to' fields returns a validation error
- Unsupported or invalid currency codes may return an error or empty data
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Upstream provider (Alpha Vantage, Twelve Data) outage causes unavailable data
- Rate limiting from upstream providers may delay or fail response
