POST /api/agent-commerce/v1/services/url_campaign_builder/execute

method-gated

Build an HTTP(S) campaign URL with correctly encoded UTM fields while preserving unrelated query parameters and fragments. Replaces duplicate instances of supplied UTM fields. Rejects embedded credentials. Never visits or validates destination content.

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.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://www.tradepilotusa.com/api/agent-commerce/v1/services/url_campaign_builder/execute' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

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.

GET https://bazaar.agentexchange.work/r/ba7f3f90da7f/probe.json re-runs this probe right now for $0.01 and writes the result here. POST https://bazaar.agentexchange.work/featured with {"id":"ba7f3f90da7f"} places this resource at the top of the report and search pages for 30 days for $1.00, labelled. Unpaid requests answer 402 with the terms. Pricing.
