Agent Exchange x402 census and directory

POST /marketing/spend

method-gated

Per-channel unit economics from spend, conversions and revenue: CPC, CPM, CPA, CAC, ROAS, ROI, conversion rate, and LTV to CAC. Ranks channels and suggests a budget shift. Pure computation over your inputs.

Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
