Free. The catalog of 7 growth coaches, the 16 modes they sell, and the current price of each. Call this first — it is generated from the same registry the paid endpoint validates against, so it is never stale.

Free. The catalog of paid real-world side effects, such as sending a review request. An action does something rather than returning advice, so it carries consent rules a coach call does not.

}

Free. The catalog of 6 small paid utilities (QR codes, time zone conversion, Markdown to HTML, calendar .ics files, website growth signals, image resize) with each one's price, request schema and a worked example. One endpoint, one job, one payment.

Free. The published request or response JSON Schema for one mode or one action. Use it to build a request you know will validate before you pay for it.

Free, and no wallet needed. Returns a schema-valid sample response for a mode: same envelope, same field names, same deliverable shape as a paid call. It is a fixed sample for the mode, not an answer to your input — that is what makes it free. Build your integration against this first.

Paid, from $0.18 per call, settled in USDC on Base over x402. Returns a growth diagnosis, the arithmetic behind it, concrete actions, and a typed deliverable. Without payment this returns the payment requirements as a structured error you can settle and retry. Try sandbox_call first if you only need to see the shape.

Paid. HAS A REAL-WORLD SIDE EFFECT: it puts a message in front of an actual person. Requires a consent block stating how and when that person agreed to be contacted. There is no sandbox for this — a simulated send cannot be told apart from a real one. Retries are safe with the same idempotency key; a new key means a genuine second send.

Paid, from $0.01 per call, settled in USDC on Base over x402. Runs one utility and returns its result. Tools contact no one and store nothing; website signals and image resize read only the one public URL you name. A request refused for its input is never charged.

Free. Returns a call you already paid for: amount, mode, usage, and the deliverable again. Only the wallet that paid can read it, and only while the receipt has not expired.
