Halowerk Royalty Split Calculator is a paid API for AI agents from creator.halowerk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Splits a total monetary amount (in minor currency units) among named recipients according to basis-point shares, using floor-and-remainder distribution to ensure exact allocation with no rounding loss.

How this service works
Requires shares totaling exactly 10,000 basis points, floors each proportional minor-unit allocation, and distributes leftover units by descending fractional remainder with a stable name tie-break. It performs arithmetic only and does not transfer funds, interpret contracts, withhold tax or resolve rights ownership.
Output
Returns each recipient's allocated amount in minor currency units (e.g. cents), computed by flooring the proportional share and distributing any leftover units to recipients with the largest fractional remainders (tie-broken by name). The sum of all allocations is guaranteed to equal the supplied total_minor_units.
Example use cases
Music co-writer royalty split
“I need to divide a $847.33 streaming payout (84733 cents) in USD among four songwriters: Maya at 4000 basis points, Jerome at 3000, Priya at 2000, and Sam at 1000 — make sure every cent is accounted for with no rounding errors.”
Creator ad revenue distribution
“A YouTube channel made $2,156.78 (215678 cents) in ad revenue this month in USD. Split it between three co-owners: Studio at 6000 basis points, Host at 2500, and Editor at 1500 — I need the exact cent amounts for each person.”
Multi-artist sync licensing fee split
“We landed a $50,000 sync deal — that's 5000000 cents in USD. Divide it among five collaborators: Producer 3500 bps, Vocalist 2500 bps, Lyricist 2000 bps, Mixer 1000 bps, and Mastering Engineer 1000 bps. Use the remainder distribution so nobody loses a cent.”
Technical details
Endpoint
POSThttps://creator.halowerk.com/v1/royalty-splitWhen to prefer
Use this endpoint when you need mathematically exact, auditable distribution of a fixed total among named recipients with defined percentage shares — especially in royalty, licensing, or revenue-sharing contexts where every minor unit must be accounted for. Prefer it over custom rounding logic when you need a stable, deterministic tie-break rule. It does not execute payments, so pair it with a payment processor to actually move funds.
Side effects
- Share basis points do not sum to exactly 10000 — returns validation error
- total_minor_units exceeds 900000000000 — returns bounds error
- Empty recipients array — returns validation error
- Duplicate recipient names may cause unexpected tie-break ordering
- Non-integer or negative share_basis_points — returns schema validation error
- Currency string not matching pattern (non-uppercase, too short/long) — returns validation error
Input
