How this service works
Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
Output

Example use cases
Travel budget conversion to KRW
“I'm traveling from the Caribbean to South Korea and want to know how much 500 ANG is worth in South Korean Won — can you convert that for me?”
Cross-border payment amount check
“I need to send money from a Netherlands Antilles account to a Korean recipient. How many Korean Won would 1200 ANG convert to?”
Single unit ANG/KRW spot rate
“What's the current exchange rate for 1 ANG in Korean Won? Just give me the base rate.”
Technical details
Endpoint
POSThttps://api.fastapi.online/f/fx/ang/krw?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to convert ANG (Netherlands Antillean Guilder) to KRW (South Korean Won) and are operating in an x402-enabled payment context on the Base blockchain. Prefer this over general FX APIs when you need a pay-per-call micropayment model with no subscription required.
Side effects
- Payment not provided or rejected — x402 payment required before execution
- Invalid or missing 'amount' field — defaults to 1 if omitted
- Exchange rate data unavailable — upstream FX feed may be down
- Non-numeric amount input — schema validation error
- Server error on self-hosted instance — 5xx response
