Not a Private modem. Private Pool = scoped credentials and Reserved IPs on the metered network. A whole dedicated 4G/5G modem with unlimited traffic, rented per day, week or month, is a Private modem: /modems/.
This page is a pointer, not a second manual. The product, pricing and the username DSL are documented once on the Pool Gateway page and in /pool/skill.md. Only what is genuinely different lives here.
-pin-lease-<leaseId>. Rotating a lease swaps the device but keeps the id, so your connection string never changes.DELETE /v1/private-pool/:id disables the pool's key and releases its Reserved IPs. A purchase-funded pool that still has a key is refused with a pointer to support, because it holds prepaid GB./private-pool/skill.md - the canonical, machine-readable reference: auth, every endpoint with real response shapes, the funding-model table, leases, and the error codes. Written for agents; equally readable by humans.
curl -s https://api.proxies.sx/v1/private-pool/pools \
-H "X-API-Key: psx_YOUR_KEY"
Returns every pool you own, each with a ready-to-use connection block. Mint a key at client.proxies.sx/account; manage pools at client.proxies.sx/private-pool.
Exit IPs are not published: the only address the API returns is observedIp on a reservation your own pool currently holds; everywhere else you get country, carrier, ASN and type. Published exit IPs get burned by anti-bot IP-reputation systems, which would degrade the network for every customer on it.
