How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with ok and paid flags, along with a structured amortization schedule array where each entry represents a payment period and includes the payment number, payment amount, principal portion, interest portion, and remaining loan balance.
Example use cases
Monthly mortgage payment breakdown
“I just got approved for a $400,000 home loan at 7.2% interest over 30 years — can you show me the full amortization schedule so I can see exactly how much goes to principal vs interest each month?”
Car loan payoff schedule
“I'm financing a $28,000 car at 5.9% interest over 5 years. Can you generate the amortization table so I can see how fast the principal goes down?”
Total interest cost analysis
“I want to know how much total interest I'll pay on a $15,000 personal loan at 11% APR over 3 years — can you generate the payment schedule period by period?”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/math/loan-amortization-schedule?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, per-period amortization breakdown for a fixed-rate loan without signing up for a financial API or managing API keys. Ideal for AI agents that need to present loan repayment tables inline, compare loan scenarios, or support financial planning tasks. Prefer over general finance APIs when you want pay-per-call pricing with no credential management.
Side effects
- Missing or invalid loan parameters (principal, rate, term) result in an error response
- Negative or zero interest rate may cause computation errors
- Extremely large loan terms may hit response size limits
- Payment failure via x402 results in 402 response blocking access
