Short answer
Anthropic and OpenAI both list Nigeria, Pakistan, the Philippines and Argentina as supported countries. For developers in those countries the usual problem is paying, not access. Local cards get declined, capped in dollars, charged extra tax or blocked for overseas use.
TeamoRouter gives you one API key for Claude, the GPT-6 family, Gemini, DeepSeek and 30+ other models. You pay per token, with no subscription. You can top up by card (through Stripe) or with USDT on the X Layer network, starting at $5. Claude Code and Codex each need two settings to connect.
This guide covers what gets in the way in each country and the payment route that works there.
How paying works on TeamoRouter
- Card: the top-up dialog takes cards through Stripe. If your card works for online purchases from foreign merchants, this is the fastest route.
- USDT: you pay with USD₮0, which is USDT on X Layer, from the OKX Wallet browser extension on a desktop browser. Your wallet signs an EIP-3009 transfer authorization for the exact amount. You don't pay gas and no card is involved. The minimum is $5. For the full walkthrough, see Pay for Claude and GPT APIs with USDT.
- What the balance covers: a single key works for every model. Claude runs on the native Anthropic protocol at
https://api.teamorouter.com. GPT-6 models (gpt-6-sol,gpt-6-luna,gpt-6-astra) use the OpenAI-compatible endpoint athttps://api.teamorouter.com/v1.
Nigeria
What gets in the way. Between 2023 and 2025, foreign-exchange shortages led Nigerian banks to cut the dollar limits on naira cards, and some banks suspended offshore transactions entirely. Limits rose again through 2026. By September, published limits included:
- GTBank: $40,000 per quarter
- FirstBank: $10,000 per quarter across POS and online
- Zenith Bank: $50,000 per year
- UBA: up to $10,000 online
- Stanbic IBTC: $8,000 per quarter on its Mastercard naira debit cards
Each bank sets its own limits, they vary by card type, and several changed more than once this year. Analysts have warned that limits could be cut again if regulators see signs of abuse. So a card that paid your API bill last quarter may not pay it next quarter.
What works. If your naira card has an international limit and isn't declined, top up by card. If it is declined, use USDT. Binance ended all its naira services in March 2024, including naira P2P trading. Nigeria's SEC gave provisional digital-asset exchange licences to Quidax and Busha in August 2024, and both let you buy crypto with naira. Wherever you buy USDT, withdraw it to your own wallet and then move it to X Layer (steps below).
Pakistan
What gets in the way. When you pay a foreign merchant by card from Pakistan, your bank collects advance income tax under Section 236Y of the Income Tax Ordinance. The tax is added on top of the charge. In fiscal 2025-26 the rate was 5% for people on the Active Taxpayers List and 10% for everyone else. Business Recorder reported that the 2026-27 budget lowers it to 0.5%. Check the tax line on your own card statement to see the rate your bank actually applies.
What works. Crypto now has a legal framework in Pakistan. Parliament passed the Virtual Assets Act, 2026 in March, which makes the Pakistan Virtual Assets Regulatory Authority (PVARA) the licensing regulator for crypto service providers. In April, the State Bank allowed banks to open rupee accounts for registered virtual-asset service providers and their clients, ending an eight-year ban (banks still can't hold crypto themselves). In December 2025, PVARA issued no-objection certificates to Binance and HTX. These are a first step toward licensing, not full licences.
If you buy USDT with rupees, prefer a provider that is going through PVARA's licensing process, and keep your transaction records. Then withdraw the USDT to your own wallet and move it to X Layer.
The Philippines
What gets in the way. In the Philippines, a declined card is usually down to a card setting, not a ban. Philippine banks let you turn overseas and online use on and off in their apps. For example, BPI's Card Control has separate switches for transactions outside the Philippines and for e-commerce, plus an e-commerce spending sub-limit. If e-commerce is off, or the sub-limit is lower than your top-up, a payment to a foreign merchant is declined. Banks also add a cross-border fee and a forex markup to dollar charges, so check your bank's fee schedule.
What works. Turn on overseas and online use for your card, raise the sub-limit if needed, then top up by card.
A note on crypto. The SEC's rules for crypto-asset service providers took effect on July 5, 2025. In August 2025, the SEC named OKX, Bybit, KuCoin, Kraken and six other exchanges as unregistered to serve Philippine residents, and PLDT, Smart and Globe have blocked the flagged sites. For the Philippines, this guide covers the card route only.
Argentina
What gets in the way. Argentine cards work abroad, but dollar charges cost more than the listed price. The PAIS tax stopped applying in December 2024. However, ARCA still adds a 30% perception under RG 5617 to foreign-currency purchases made by credit or debit card when you pay the statement in pesos, and online purchases are included. The perception is an advance payment on income or personal-assets tax, not a final cost, but you still pay it up front. Separately, card issuers collect VAT on digital services bought from foreign providers under RG 4240, and 21% is the general VAT rate.
What works. Under the rule, the 30% perception applies only to the part of the statement you pay in pesos. If you pay your card statement with your own dollars, that part isn't subject to it. Many Argentines already hold dollars as stablecoins: in Chainalysis's 2024 data, stablecoins made up about 62% of Argentina's crypto transaction volume, well above the global average. If you hold USDT, a TeamoRouter top-up doesn't involve a card at all. Withdraw the USDT to your own wallet, move it to X Layer and pay.
Getting USDT onto X Layer
For Nigeria, Pakistan and Argentina, the steps are the same:
- Buy USDT on a platform you can legally use where you live. That can be a local exchange or a P2P marketplace. On a P2P marketplace, you pay another user by bank transfer or mobile money, and the platform releases the seller's USDT from escrow once the seller confirms your payment. Keep the trade inside the platform: pay only the account shown on the order, and don't mark an order as paid before you've paid.
- Withdraw it to your own wallet. Install the OKX Wallet extension in Chrome, Edge or Brave on a desktop computer, create a wallet, and copy your address. A balance that's still on an exchange can't pay.
- Move it to X Layer. If your platform supports withdrawals to X Layer, choose that network. If it doesn't, withdraw on a network that the official usdt0.to Transfer page supports, such as Tron or Arbitrum, and transfer it to X Layer there. You pay gas once on the source chain. Send a small test amount first. Picking the wrong network is the most common mistake.
- Top up. In the TeamoRouter console, open the top-up dialog and click Pay with crypto. Approve the connection, switch to X Layer when the wallet asks, and sign. You don't pay gas on this step.
Connect Claude Code and Codex
Create an API key first.
Claude Code (macOS / Linux). Claude uses the base URL without /v1:
export ANTHROPIC_BASE_URL=https://api.teamorouter.com
export ANTHROPIC_AUTH_TOKEN="your TeamoRouter API key"
For Windows and model settings, see Install and connect Claude Code.
Codex CLI (~/.codex/config.toml):
model_provider = "teamorouter"
model = "gpt-6-sol"
[model_providers.teamorouter]
name = "TeamoRouter"
base_url = "https://api.teamorouter.com/v1"
env_key = "OPENAI_API_KEY"
wire_api = "responses"
Then run export OPENAI_API_KEY="your TeamoRouter API key". The OpenAI SDK works with the same /v1 base URL. Full steps: Install and connect Codex.
FAQ
Is Claude available in Nigeria, Pakistan, the Philippines and Argentina? Yes. Anthropic's supported-regions list includes all four, and so does OpenAI's API country list. What usually goes wrong is the payment, not access.
Do I need a card? No. A USDT top-up doesn't involve a card. If you have a card that pays foreign merchants without problems, you can use it instead.
What's the minimum, and do I pay gas? The minimum top-up is $5. You don't pay gas when you pay on X Layer. If you move USDT to X Layer from another chain first, you pay that chain's network fee.
Can I pay from my phone? Use a desktop browser with the OKX Wallet extension. Mobile browsers usually don't have the extension and show a "no wallet found" error.
My top-up hasn't arrived. Who do I contact? Message TeamoRouter support on Telegram at @teamorouter, and include your wallet address and the time you paid.
