Commercial and valuation metrics, derived read-only from tables the gateway already writes: the x402 settlement journal (migration 0011), the identity plan/Stripe columns (0012), `api_keys.first_success_at` (0015) and `usage_counters` (0001).

What the keyless demo lane (SN_DEMO_RPM) gave away.

Counting only. Keyless traffic is free by design and this endpoint changes nothing about that: no quota, no block, no charge. It exists to answer the question the demo lane could not answer before, how much of the premium differentiator (truck dimensions, hazmat, ADR tunnel_code) is being served for nothing, so the enforcement decision, if it comes, is taken on evidence.

Signup → key → activation → paid funnel, as counts per stage.

Revenue signals the database genuinely holds: settled x402 payments, how many identities are linked to a Stripe customer, and the plan distribution.

Deliberately not Stripe MRR: the gateway stores no subscription amounts, prices or invoices, so any monthly-recurring figure would be fabricated. stripe_customers and plans are the honest inputs, and the console multiplies plan counts by published list prices under an explicit "estimate" label. Prepaid-rail money for the commercial snapshot. Credits only, the ledger journals credits and not debits, so consumption has no time axis yet and is deliberately absent rather than approximated.

Month-on-month retention proxy, oldest month first.

Standard/premium call mix over the trailing window, plus the busiest endpoints.

The class split reuses the overview's endpoint-label rule: /adr/check is the premium-by-path endpoint, everything else counts as standard. Truck/ADR calls on mixed endpoints are classified per request body at bill time and are indistinguishable in usage_counters, so premium is a floor, not an exact billing total.
