Business model

derived from the price, the rail and the access rule — nothing inferred
How it charges Metered per call

A price per call is published (0.001 USDC per call). This is the model that x402 and pay-per-request APIs use: the buyer pays for each invocation, not for a seat.

Who pays Paying client with a wallet

The 402 challenge is addressed to the caller directly (Base · USDC). Whoever calls pays per request; no account or contract is needed. That is a machine-to-machine model — and it means each transfer is small.

Distribution Distribution

Discoverable through the x402 Bazaar.

What the numbers support What the numbers support

No measured figure exists for this service. Nothing here is derived from an assumption.

What is not knowable What is not knowable from here

Revenue, cost, margin and buyer identity. A published price is not a charge, and an observed transfer is not a purchase — it can be a treasury move, a refund or a test. We hold no funds and process no payments, so we never call this profit.

Opportunity insights

2 findings from measured data
  • Payment attribution is blocked

    The payout address is shared with 48 other service(s). That is normal for facilitator and platform addresses, and it is why this profile shows no inflow figure. The volume exists — it just cannot be split without inventing a rule.

  • Category benchmark

    27 of 3,155 services (0.9%) in Dev & Code have attributable inflows; 903 have a source-measured call count. Median measured calls: 2.

The payout address is also published by 48 other service(s); the volume cannot be attributed to one of them.

Why revenue is “unknown”. A revenue figure needs a receipt: an amount a buyer actually paid for this service. We hold none for this entry, and we hold no funds at all. What we have instead is nothing measurable: no price, no attributable address, no receipt. The payout address is also published by 48 other service(s); the volume cannot be attributed to one of them.

A payment rail is where the provider asks to be paid. It is not proof that anything was paid through it. See evidence levels.

Provenance

One row per statement. “Verified” means we checked it ourselves and the finding is quoted. “Provider claim” means we read it in the provider's own record. “Not found” is a statement about our search, not proof of absence.
