Why an API, not a calculator

Built for the systems that price at scale.

Free web calculators are eBay-only and unmaintained. hunta is the authoritative, programmatic source — the thing a repricer or analytics tool can actually depend on.

Authoritative & maintained

Built on eBay's published fee schedule and version-stamped — when eBay changes a tier we update the schedule and surface it in bpf_version, so you can pin to a known version.

Every direction

Forward (price → fee), inverse (displayed total → item + embedded fee), and batch up to 1,000 items — built for repricers and analytics.

Penny-exact

Decimal maths, round-half-up — never floats. Every response itemises the buyer and seller sides with machine-readable flags.

Full control

One call. The whole fee, itemised.

Forward

Price in, penny-exact fee out.

Inverse

Strip the fee out of a displayed total.

Batch

Up to 1,000 items in one request.

The moat

Streamed against eBay, in real time.

Fee schedules move — so a delta monitor streams eBay's published schedule in real time and catches a change the moment it lands. Every response is stamped with the bpf_version it used, so you always know which schedule produced a figure — and can verify it against eBay's current fees.

Published source — every figure derives from eBay's own published fee pages.

Versioned — the active schedule is stamped as bpf_version on every response.

Verify — eBay can change fees at any time, so always check against eBay's current official fees before relying on a figure.
