Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/finance/mortgage/calcWhen to prefer
Choose this endpoint when you need a quick, pay-per-call mortgage computation without setting up a dedicated financial API key. Ideal for agents handling one-off or infrequent mortgage calculations paid in USDC via x402, especially when already using OmniAPI for other finance or crypto endpoints in the same workflow.
Side effects
- Missing required query parameter returns 400 error
- Invalid numeric values for loan amount or rate may return calculation error
- Extremely unusual loan terms (e.g. 0% rate or 0 term) may produce unexpected results
- Payment processing failure via x402 returns 402 before computation
- Malformed request body returns generic API error
