}Three steps, no account anywhere.
Call the route once, unpaid. It answers 402 with the price, the token, and the address that gets paid.
Sign a USD₮0 authorization for that exact amount with your own wallet.
Send the same request again with the signature. The artifact and its signed receipt arrive in one response.
The one-command buyer below runs all three steps and checks the receipt signature at the end. Drop --pay to print the challenge without paying anything.

}Every field is optional. Send an empty body for the baseline analysis, or supply fields to tailor it. The body is bound to the payment, so a different body is a different purchase.
Every delivery also carries the settlement transaction hash, a SHA-256 hash of the artifact, and an Ed25519 receipt anyone can check at /api/receipts/verify.
STAGE 3 OF 5
Stage 3 of 5. It settles one decision: why the listing is not converting, and the exact fix.
NEXT / STAGE 04 OF 5
Because once a listing converts on its own, the cheapest growth is another agent selling it for you.
You are buying one answer, not a subscription. Payment and delivery happen in the same request, and the receipt proves it without anyone taking our word for it.
