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 (0.2 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

The source counted 1 calls in 30 days; at the published price that is $0.20 of activity — not revenue.

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 1 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.

    How attribution works →
  • Category benchmark

    91 of 15,487 services (0.6%) in Other services have attributable inflows; 2,085 have a source-measured call count. Median measured calls: 2.

What the provider says

Accepts a JSON object with a non-empty text string up to 100000 characters and returns text counts, estimated reading time, ten most frequent non-stop words, and a slug of the first sentence.

The payout address is also published by 1 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 an activity value of $0.20 — the source's call count multiplied by the published price. That is what the list price implies, not what anyone paid. The payout address is also published by 1 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.
