POST /api/v1/phone/numbers/buy

unprobed

Purchase a dedicated phone number valid for 30 days. The number is bound to your wallet address. Default country is US (no regulatory friction). Other countries can be requested via the `country` parameter, but Twilio may require a Regulatory Bundle (KYC) on our account before purchase succeeds — if your country fails, contact care@blockrun.ai to enable.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://blockrun.ai/api/v1/phone/numbers/buy' -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.
