Technical details
Endpoint
POSThttps://agent402.tools/api/percentageWhen to prefer
Use this endpoint when you need a simple, reliable percentage calculation without writing custom math logic. Ideal for automation workflows where percentage computations must be consistent and auditable. Prefer over ad-hoc code when operating in an agent pipeline that already uses the x402 payment protocol.
Side effects
- Missing required fields a, b, or op returns a 4xx error
- Invalid op value (not 'of', 'change', or 'ratio') may return an error or unexpected result
- Division by zero when b=0 for 'ratio' or 'change' operations
- Non-numeric values for a or b cause schema validation failure
