Pricing & Radar

Pricing is transparent by design — no bid shading, no hidden take. You can read the fee split on every delivery.

The fee

The auction clears at the second price (supply-facing gross). At confirmation (billing time, not auction), a transparent platform fee is carved from the gross:

• spend = gross (what the buyer is billed),
• fee = the exchange take,
• net = the supply payout,
• invariant: fee + net === spend, exact.

The rate (fee_bps) is snapshotted onto each buy at creation, so a later change never rewrites history. Read the current published tiers at /pricing.

Consumption

On top of the percentage, processing is metered pay-for-what-you-use (Cloudflare-style: an included bucket + a published overage). Prepaid, no custody — a meter, not a bank.

The Radar (fill-risk defense)

Fronting unbounded cost against fill-dependent revenue is how exchanges lose money. The Radar is a glass-box expected-value defense, in two halves:

• Supply shaper — per source, learn the recent confirmed yield and shape before the fan-out, so we never pay to process inventory that won’t fill. A fast spend circuit-breaker bounds cost before fill is even known.
• Demand smart fan-out — per DSP, learn the bid pattern and call the DSPs that add value, keeping the price-setter. Fewer wasted calls, same clears.

Your control (Radar knob)

A single relaxed → aggressive level per verified seller governs both halves. Default is auto (full competition, seller-favorable) — leaner is opt-in, and you own the trade-off. Read and set it at /v1/radar, and inspect your own per-source yield + fan-out decision from the same endpoint. Glass box: you see the numbers.
