ISP Proxy API Use and Residential Proxy API Use: Two Products Beside the Line
The main product of Mobile Proxies US is a single carrier line assigned to one customer and exposed through an account API. The dashboard carries two further products: static ISP addresses, and metered residential (plus mobile pool) data. People search for an isp proxy api or a residential proxy api meaning a product they can drive from scripts; this page explains, in plain terms, what each of these two products is, how it is priced, how it is bought and how the resulting credentials are used from code. Our catalogue renders the tables below; the prose around them is the explanation.
Static ISP addresses: the table
Every row is a fixed IPv4 address belonging to the American carrier or cable operator it names, exiting via Virginia, held by your account for the chosen term. Minimum order 10 addresses; 1-, 3-, 6- or 12-month terms; a single credential set for the whole order. The right-hand column gives the monthly isp proxy price for each address.
- Term: 1, 3, 6 or 12 months
- Login: username and password / IP whitelist / SOCKS5
- One login per order
- Order size: 10 IPs and up
Residential and mobile pool data: the two per-GB cards
Here you buy gigabytes rather than addresses. Residential data costs $2 per GB and runs over household connections in upwards of 190 countries, with targeting down to country, then state, city or ASN, and either a session held up to half an hour or a fresh address on each request. Mobile pool data costs $10 per GB and runs over handsets on live 4G and 5G connections, shared, with country, state and city targeting. Gigabytes carry no expiry date.
- 190+ countries
- Target: country, state, city, ASN

- Or a new IP per request
- Data never expires
- Top up any time
- Shared 4G and 5G pool
- Target: country, state, city
- Sticky up to 30 minutes

Definitions, so the words mean one thing
Static ISP proxy: a fixed IPv4 address registered to an American carrier or cable operator (Comcast, AT&T, T-Mobile, Frontier, RCN and a few others in the table), served from hosting and exiting via Virginia. The address stays the same for the whole term. It is classified by destinations as an ISP or residential-range address with a hosting-style stability. Priced per IP per month.
Residential proxy data: access to a rotating pool of household connections in many countries through one gateway, priced per gigabyte transferred. The address is selected per request by parameters you encode in the proxy username (country, state, city, ASN, session). Mobile pool data: the same model over shared handsets on live 4G and 5G connections, metered per GB, with country, state and city targeting. Neither is a dedicated line, which is the product every other page here describes.
What an ISP order gives you
At least 10 addresses drawn from a single table row, on a 1-, 3-, 6- or 12-month term. A single credential set covers the whole order: user and password login, a whitelisted source IP, or SOCKS5. Auto-renew can be switched on; it is off unless you do. An extension is charged at the order's original monthly rate for each address. Early removal brings no refund. US rows exit via Virginia whatever the owning company's footprint, so an ISP address geolocates to Virginia or to the owner's registered location rather than to a metro you pick.
In code an ISP address behaves like any static proxy: host, port and credentials go into configuration, one entry for each address, and your own code spreads requests across them. No rotate call exists, because a fixed address is the point. Most isp rows cost $2.40 a month for each address; the AT&T Native isp row costs $4 a month for each address; the T-Mobile Legacy isp row costs $2.10 a month for each address; one Canadian isp row is listed but sold out at present.
- Minimum 10 addresses, all from a single row.
- 1-, 3-, 6- or 12-month terms; an extension is charged at the original monthly rate for each address.
- A single credential set covering the order: user and password, whitelisted source IP, or SOCKS5.
- Auto-renew off unless enabled; no refund on early removal.
- US rows exit via Virginia.
What a residential or mobile pool order gives you
A gigabyte balance plus a gateway. In the dashboard you generate proxy strings, picking a country and, if wanted, a state, city or ASN, and picking a held session (the same address for as long as half an hour, keyed by a session value) or a fresh address on every request. The residential pool covers upwards of 190 countries at $2 per GB; the mobile pool is shared handsets on live 4G and 5G connections at $10 per GB with country, state and city targeting. Bytes in both directions are deducted, error pages and retries included.
Gigabytes carry no expiry date. Refill at will; with auto top-up enabled, a refill triggers once less than a tenth is left. Cancel a residential or mobile pool order inside its first seven days and whatever you have not used is credited back to the account. In code the pool is driven by building the username for each request or session and sending through the gateway; changing address is a property of the request rather than a call.
Choosing between the three, by job
Dedicated mobile line: one identity on a US carrier address for hours or weeks; QA and automation as a US mobile user; webhook, SMS and verification flows; anything with heavy or unpredictable transfer, since the line meters no data. Static ISP: a fixed US address that must not change for a month or a year, for allow-lists, long-lived logins on services that tolerate ISP ranges, and tasks that need the same address every day. Residential or mobile pool data: breadth; many addresses in many countries for public reads where no identity persists and the byte count is predictable.
The products are not substitutes. A pool cannot hold one mobile identity for a week; a line cannot give you a thousand countries; an ISP address is not mobile and does not rotate. Teams commonly hold one or two lines plus a small residential balance, and add an ISP batch when a fixed address is required.
Buying and where the credentials appear
At cp.mobileproxiesus.com go to Buy Proxy, then the tile marked Mobile, Residential or ISP; the Telegram bot at @mobileproxiesus_bot sells the same three. Pay from your balance, topped up by card, PayPal, Bitcoin, USDT including TRC-20, Ethereum, Zelle or bank wire. Orders appear on My Proxies with their credentials, terms and renewal state. Copy ISP and pool credentials from there into your configuration; your dedicated lines remain the licences the account API lists, each with its own rotation link.
The same people answer for all three products, around the clock, at [email protected] and in the bot.
Price list in one place
ISP rows: T-Mobile Legacy $2.10 a month for each address; Comcast Native, Frontier Native, RCN Fresh, AT&T Fresh and the rows marked likewise $2.40 a month for each address; AT&T Native $4 a month for each address; minimum 10 addresses; 1 to 12 months. Residential data: $2 per GB. Mobile pool data: $10 per GB. For comparison, a dedicated 4G line is $5 a day, $29 a week or $66 a month and a dedicated 5G line $6 a day, $33 a week or $77 a month, with no data meter.
ISP proxy API and residential proxy API: common questions
Is there a separate isp proxy api or residential proxy api endpoint?
Purchases happen in the dashboard or the bot. The resulting ISP and pool credentials are ordinary proxy logins you use from any code; pool targeting is encoded in the username per request.
Where does an ISP address geolocate?
US rows exit via Virginia and carry the owning carrier or cable operator's registration. Metro choice belongs to the dedicated line, not to ISP addresses.
How does a held session work on the residential pool?
Include a session value in the username and the gateway keeps the same address for as long as half an hour. Leave it out and every request gets a fresh address.
Do gigabytes expire?
They do not; the balance waits until it is spent. Cancel the order inside seven days and the unspent part is credited back to the account.
What is the minimum ISP order?
10 addresses, a single row, a one-month term. 3-, 6- and 12-month terms exist too, and an extension is charged at the original monthly rate for each address.
How does the mobile pool differ from a dedicated line?
The pool is shared handsets metered per GB, changing address on request. A line is one SIM held by you for the term, unmetered, with its own API object.
Can ISP addresses authenticate by source IP instead of a password?
Yes. The order's single credential set can be a user and password, a whitelisted source IP, or SOCKS5.
Which of the three should a developer start with?
For QA and automation as a US mobile user, a line, hourly first. Add residential data for wide public reads and an ISP batch when a fixed address is required.
