POSThttps://x402deploy.vercel.app/api/fxWhen to prefer
Choose this endpoint when you need live foreign exchange rates without managing API keys or subscriptions — ideal for AI agents that can handle x402 micropayments and need on-demand forex data at very low per-call cost. Prefer it over free FX APIs when rate limits or key management are a concern, and over heavier financial data platforms when only spot rates are needed.
Side effects
- Invalid or unsupported base currency code returns an error or empty rates
- Malformed symbols string (e.g. typos in currency codes) may return partial or empty results
- Rate data may be slightly delayed depending on upstream provider refresh cadence
- Payment failure via x402 protocol will block the request entirely
- If the x402 payment is not properly handled, a 402 Payment Required response is returned
