How this service works
Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
Output
Returns an object containing the converted currency amount from ANG to HUF, likely including the exchange rate applied and the resulting value in Hungarian Forint.
Example use cases
Travel budget calculation in HUF
“I'm traveling from Curaçao to Hungary and want to know how much 500 ANG is worth in Hungarian Forint so I can plan my spending money.”
Business invoice reconciliation ANG to HUF
“We received a payment of 1200 ANG from a Caribbean partner — can you convert that to HUF so I can record it in our Hungarian accounting system?”
Quick FX sanity check for remittance
“Before I send money, can you tell me the current conversion for 75 ANG into Hungarian Forint?”

Endpoint
POSThttps://api.fastapi.online/f/fx/ang/huf?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need ANG-to-HUF conversion, are comfortable with per-call USDC micropayments via x402, and want a lightweight self-hosted alternative to large FX API providers. Well-suited for agents that already handle x402 payment flows and need ultra-low-cost FX lookups at $0.0002 per call.
Side effects
- Payment not provided or insufficient — returns HTTP 402 requiring USDC micropayment on Base before execution
- Invalid or missing amount field — may return a validation error or default to amount=1
- Service unavailable — self-hosted endpoint may be offline or rate-limited
- Unsupported or stale exchange rate data — conversion may reflect a cached or outdated FX rate
