POST /v1/dns-srv-caldav

gone

Call when an agent needs SRV records at _caldav._tcp.{hostname} for CalDAV. The caller sends the registrable domain, not the underscored name. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-caldav first.

Verdict: dead listing. 404/410: gone (was unprobed in the census).

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/904e0a357bf9/probe.json re-runs this probe right now for $0.01 and writes the result here.
