How this service works
Split an integer amount of cents among N ratios with zero rounding loss (Fowler's allocation algorithm) - the parts always sum back to the original amount.
Output
An array of integer cent amounts, one per input ratio, that sum exactly to the original amount_cents. Rounding remainders are distributed using Fowler's algorithm so no cent is lost or double-counted.
Example use cases
Split restaurant bill by meal cost
“We have a group bill of $84.00 (8400 cents) to split among 4 people who ordered meals costing $22, $18, $25, and $19 respectively — use those as the ratios and make sure the total adds up exactly.”
Allocate revenue shares to co-founders
“We earned $10,000 (1000000 cents) in revenue this month and need to split it between two founders with a 60/40 equity split — give me the exact cent amounts with zero rounding error.”
Distribute subscription cost across departments
“Our $299.99 (29999 cents) SaaS subscription should be allocated to 3 departments by headcount: 12, 7, and 5 employees — what does each department owe in cents, making sure it adds up exactly?”

Endpoint
GEThttps://x402.agentindex.world/money/allocate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need mathematically exact integer cent allocation with zero rounding loss — especially when splitting among multiple parties by arbitrary weighted ratios and the sum must always equal the original total. Prefer over floating-point division or custom code when correctness and auditability of cent-level allocation matter, such as in financial, billing, or revenue-sharing contexts.
Side effects
- Empty ratios array (minItems:1 violated) returns a validation error
- Negative amount_cents (minimum:0 violated) returns a validation error
- Non-integer ratio values cause schema validation failure
- All-zero ratios array may cause division-by-zero error
- Network or payment failure returns HTTP 402 or timeout
