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 currency value from AOA to TZS for the given input amount, based on current exchange rate data processed through the self-hosted AI gateway.
Example use cases
Cross-border Africa trade pricing
“I'm sending an invoice to a client in Tanzania but my costs are in Angolan Kwanza — can you convert 10000 AOA to TZS so I can quote them the right price?”
Travel budget estimation Angola to Tanzania
“I'm planning a trip from Angola to Tanzania and want to know how much 250 AOA is worth in Tanzanian Shillings.”
FX monitoring for remittance
“What is the current TZS value of 1 AOA? I need to check the exchange rate before sending money to Tanzania.”
Technical details
Endpoint
POSThttps://api.fastapi.online/f/fx/aoa/tzs?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need AOA-to-TZS currency conversion and are operating in an x402 micropayment-enabled agent context (USDC on Base). It is best suited for lightweight, per-call FX lookups where cost per query must be minimal ($0.0002 USDC). Prefer this over general-purpose FX APIs if you are already integrated into the x402 payment protocol and need Africa-corridor currency rates without setting up a separate FX subscription.
Side effects
- Payment not provided or insufficient USDC micropayment — returns HTTP 402 Payment Required
- Invalid or missing amount field — malformed request or default of 1 used
- Exchange rate data unavailable — gateway may return an empty or error response
- Network timeout on self-hosted instance — no SLA guarantee
- Response schema is generic object — structure may vary or be undocumented
