Cost Tracing

Know what every pricing decision cost you.

Cost Tracing shows the input units, output units, multiplier, and final cost for every compute call — computed by the same helper the router uses, so the dashboard, the marketing site, and the invoice all match.

last-price.ai/costs

Cost Tracing — drill from a tenant down to a single compute call.

What you can do

See cost per call, per function, per tenant, and per route in one view.
Drill from any total down to the individual usage event that caused it.
Filter by function, time range, customer, or routing strategy.
Export usage events to your warehouse via webhook or the Usage API.
Reconcile against invoices — the same formula produced both numbers.

One trace, end to end

Worked example

metering.input_units      = 120
metering.output_units     = 64
function.cost_per_unit    = $0.005
function.cost_multiplier  = 1.5×
─────────────────────────────────────────
metering.cost             = $0.002340

Computed live with computeMeteringCost(input, output, cost_per_unit, multiplier) from packages/pcn. Factors: METERING_INPUT_FACTOR = 0.001, METERING_OUTPUT_FACTOR = 0.003.
