How this service works
Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
Output
Returns a JSON object containing the converted value in XOF (West African CFA francs) for the given input amount, along with any exchange rate metadata provided by the service. The response structure is open (schema: object) so additional fields such as rate, source currency, and timestamp may be included.
Example use cases
Remittance amount planning to West Africa
“I want to send money to Senegal — how many CFA francs (XOF) will 500 euros convert to at today's rate?”
E-commerce pricing in XOF
“I'm listing a product priced at $19.99 USD on a West African marketplace — what's that in XOF so I can set the local price?”
Travel budget conversion to CFA francs
“I'm heading to Côte d'Ivoire and have 1000 GBP to spend — convert that to XOF so I know my rough budget.”
Technical details
Endpoint
POSThttps://api.fastapi.online/f/fx/aoa/xof?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a micropayment-gated, on-demand FX conversion specifically to or involving XOF (West African CFA franc), particularly in workflows already using the x402 payment protocol on Base/USDC. Prefer it over free public FX APIs when you need a pay-per-call model with no subscription overhead and are already integrated with x402.
Side effects
- Missing or failed x402 micropayment results in HTTP 402 Payment Required before the conversion is executed
- Invalid or missing 'amount' field may return a 422 Unprocessable Entity or default to converting 1 unit
- Service downtime or gateway errors return 5xx responses
- Stale exchange rate data if the underlying FX feed is delayed
