Endpoint
POSThttps://x402.forgemesh.io/percent-changeWhen to prefer
Choose this endpoint when you need a quick, exact percentage computation without writing your own math logic — especially useful when you need all five percentage operation types covered by a single consistent API, or when building agents that handle dynamic user percentage queries at runtime.
Side effects
- Missing required fields a or b returns a validation error
- Invalid operation string (not one of: of, is_what_percent, change, increase, decrease) returns an error
- Non-numeric string values for a or b may cause a computation error
- Division by zero if b=0 on certain operations
- Payment failure if USDC balance insufficient for $0.001 fee
