How this service works
Base USDC Decimal Rounding: Base USDC Decimal Rounding checks whether a decimal USDC amount fits six fractional digits exactly from bounded caller-supplied values without an external provider. Call Base USDC Decimal Rounding before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for Base USDC Decimal Rounding as versioned determi…
Output
Returns a JSON object containing the raw integer representation, the formatted decimal string (e.g. '0.001000'), the number of fractional digits, and a boolean indicating whether the amount fits within USDC's 6-decimal precision. Also includes an audit block with input hash and confirmation that no external calls were made and data was not retained.
Example use cases
Pre-flight USDC payment check
“Before I send a USDC payment on Base, can you confirm that the amount '500.123456789' fits within six decimal places and give me the correctly formatted value?”
Format raw integer for EVM transfer
“I have a raw amount '2500000' that I need to format as a proper USDC decimal for a Base network transaction — can you run the decimal rounding check on it?”
Validate stablecoin amount precision
“I'm building a DeFi workflow and need to verify that '0.0000001' fits the six-decimal limit used by USDC on Base — can you run that decimal precision check for me?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-usdc-decimal-roundingWhen to prefer
Use this endpoint when you need to validate, format, or preflight a numeric amount specifically for Base network USDC transactions, which enforce 6-decimal precision. Prefer this over generic rounding utilities when you need the EVM-specific integer representation alongside the decimal form and an explicit fits_six_decimals flag for safe on-chain payment preparation.
Side effects
- Missing or empty 'amount' field returns a validation error
- Non-numeric string input may cause a parsing failure
- Amount string exceeding 8192 characters is rejected
- Malformed JSON body returns a 400-level error
