Duo Data Utilities – Money Allocation / Split is a paid API for AI agents from api.duoleads.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-02).
Splits a monetary amount into N equal parts or by custom ratios, distributing any remainder cent-by-cent using a deterministic rule so parts always sum exactly to the original.

How this service works
Split a money amount into shares without losing or inventing a cent. Divide evenly into N parts, or by a list of ratios, and the remainder is distributed one minor unit at a time by a named, deterministic rule — largest-remainder, first-wins or last-wins — so the parts always sum exactly to the original. Uses Unicode CLDR minor-unit digits, so zero- and three-decimal currencies work (CLDR differs from ISO 4217 for a few, e.g. IDR, HUF: 0).
Output
Returns a JSON object with an array of share amounts in decimal and in minor units, the applied remainder rule, total, currency code, minor unit precision, and the number of minor units redistributed. Also includes metadata: request ID, computation timestamp, CLDR data source attribution, and a deterministic flag confirming the result is reproducible.
Example use cases
Split restaurant bill evenly
“We have a restaurant bill of €87.50 EUR to split equally among 5 people — can you divide it so every share is exact and the cents add up correctly, using the largest-remainder rule?”
Allocate revenue by ownership ratios
“I need to distribute $1,250.00 USD among three partners with ownership ratios of 2, 3, and 5 — split the amount by those ratios and make sure it totals exactly, with any leftover cents going to the first partner using the first-wins rule.”
Divide subscription cost into monthly installments
“Break an annual software fee of ¥127,000 JPY into 12 monthly installments that add up to exactly the full amount, with any remainder assigned last using the last-wins rule.”

Endpoint
GEThttps://api.duoleads.com/v1/num/allocate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need mathematically guaranteed exact allocation of a money amount — where the sum of shares must equal the original to the last minor unit. Ideal for bill splitting, revenue sharing, installment schedules, or any financial distribution where floating-point rounding errors are unacceptable. The deterministic remainder rules (largest-remainder, first, last) make results auditable and reproducible. Prefer over general-purpose division when currency-aware minor-unit handling is required, especially for zero- or three-decimal currencies like JPY or KWD.
Side effects
- Missing required 'amount' or 'currency' parameter returns a validation error
- Neither 'parts' nor 'ratios' supplied causes an error
- 'parts' value outside 1-1000 range rejected
- 'ratios' list exceeding 1000 entries or individual ratio exceeding precision limits rejected
- Amount absolute value ≥ 1e12 rejected
- Invalid ISO 4217 currency code returns an error
- All-zero ratios list is invalid
- Network or server errors may return non-200 HTTP status
