How this service works
Check token amount decimals, dust, unusually round/precise values and mismatch against a stated invoice amount.
Output
Returns a JSON object with a boolean `valid` flag, an `ok` status, an `issues` array listing any critical problems (e.g. amount mismatch, decimal overflow), and a `warnings` array for non-critical concerns like rounding.
Example use cases
Example prompt
“Before I send this payment, sanity check that the amount '1000000' matches the invoice amount '1.00' for a token with 6 decimal places — flag any precision or mismatch issues.”
Technical details
Endpoint
POSThttps://gateway.apiosk.com/crypto-sanity/check/amountWhen to prefer
Use this endpoint when you need to programmatically verify that a cryptocurrency token amount (on-chain representation) correctly matches an expected invoice amount, especially when dealing with token decimal precision. Ideal as a pre-flight check before executing a crypto payment to catch rounding, overflow, or mismatch errors.
Side effects
- Missing or malformed `amount` field returns validation error
- Token decimals value out of expected range causes processing failure
- Non-numeric string in amount field causes parse error
- Invoice amount and amount in incompatible formats returns issues array populated with mismatch errors
