You wrote your code, hit "Add billing", and Stripe rejected your card. This page is for you. We compare every credible alternative — gateway and direct provider — by how friendly they actually are to developers in India, Brazil, Russia, Indonesia, the Middle East, and the rest of the world that doesn't get treated as a Stripe primary market.
OpenAI's signup is technically open globally, but the payment processor (Stripe) silently rejects a meaningful share of cards from non-G7 countries. The pattern is well-documented: an Indian RuPay-linked Visa, a Brazilian Itaú card, an Indonesian BCA debit, a Vietnamese Techcombank card — they all see "transaction failed" with no explanation. The developer thinks they did something wrong. They didn't. Stripe's risk model treats their card as too high-risk to bother with.
The good news: there are at least seven serious alternatives, each with tradeoffs. The bad news: most "OpenAI alternative" articles online are auto-generated SEO spam that just lists every provider on the internet without explaining which one fits your situation. This page tries to actually answer the question.
Seven providers worth knowing about, grouped by what they are:
You probably want a multi-model gateway. The inference clouds host open-weight models only — they cannot give you GPT-4o or Claude. The logging proxies are observability tools first, not really billing solutions for users without cards.
| Provider | Needs US/EU card? | Crypto? | Region blocks? | KYC? |
|---|---|---|---|---|
| Stormfire | No | USDT (4 chains) | None | None |
| OpenRouter | Card preferred | USDC-Base only (+5.5%) | Sanctioned countries blocked | Stripe risk review |
| AIMLAPI | No | Multi-coin via processor | Limited | Processor KYC may apply |
| Together AI | Yes (Stripe) | No | Standard Stripe rules | Stripe risk review |
| DeepInfra | Yes (Stripe) | No | Standard Stripe rules | Stripe risk review |
| Fireworks AI | Yes (Stripe) | No | Standard Stripe rules | Stripe risk review |
| Helicone | Yes (Stripe) | No | Standard Stripe rules | Stripe risk review |
If your card doesn't work, only three providers are usable without going through painful workarounds: Stormfire, OpenRouter, AIMLAPI. The rest of this page focuses on those three and explains when even one of them might not be your best move.
Built specifically for the "no card" use case. USDT on TRC20, ERC20, BEP20, Polygon. 30+ frontier models including GPT-5, GPT-4o, Claude 3.7, Gemini 2 Pro, DeepSeek v4. 0% platform fee — they charge what the upstream provider charges. $15 minimum top-up. Tokyo-region for APAC latency. OpenAI SDK drop-in (just change base_url).
The most well-known multi-model gateway, US-based, US-centric infrastructure. 300+ models including a long tail of open-weight fine-tunes. USDC-on-Base with a 5.5% surcharge if you go crypto. Card path is smoother but subject to Stripe risk review. Great for "I need every model under one roof"; expensive if you're price-sensitive.
Multi-model gateway with crypto support via NowPayments / Coinbase Commerce. Supports more coins (BTC, ETH, USDT, USDC) but at the cost of a 3–5% effective surcharge from the third-party processor. Reasonable backup if Stormfire or OpenRouter both fail you for some reason.
These are not OpenAI alternatives — they're Llama / Mistral / DeepSeek alternatives. They host open-weight models on their own GPUs, often with attractive pricing for batch workloads. They all use Stripe. If you can't pay Stripe, you can't use them directly. You can, however, access their models via Stormfire or OpenRouter as a proxy.
Observability-first. They're great if you want logs, prompt versioning, and analytics, but they expect you to BYO upstream key. They don't solve the "I can't pay OpenAI" problem.
Most affected by Stripe rejections. RuPay-linked Visas and Mastercards fail with high frequency. Stormfire is the cleanest path: withdraw USDT-TRC20 from WazirX (when accessible), CoinDCX, or international Binance. $15 top-up arrives in minutes.
Brazilian-issued cards trigger Stripe holds on AI and SaaS merchants. Pix doesn't help for international vendors. Stormfire works via USDT from Bitso, Mercado Bitcoin, or Binance Brazil.
OpenAI explicitly blocks. Most US-based gateways either block too or work intermittently. Stormfire's posture is to serve the global open internet — we don't claim sanctions-busting capability, but we don't add country-level blocks either. Use at your own legal discretion.
Local cards generally fail Stripe. USDT is widely available on regional exchanges. Stormfire's Tokyo region also gives you ~50ms RTT, which matters for streaming UIs.
If you've left mainland China but kept your CNY-only Bank of China card, foreign AI APIs are unreachable. USDT bypasses this. We don't serve mainland China traffic for compliance reasons, but APAC-egress users connecting from HK, Singapore, Taiwan, Tokyo, etc. work fine.
Local cards mostly fail. USDT on Binance P2P or local OTC desks is the standard workaround. Stormfire on TRC20 fits this flow.
Currency controls make USD-denominated SaaS painful. USDT solves this elegantly because it's already the de facto store-of-value in those economies.
Talk to your lawyer. We're not in the business of telling you what's legal in your jurisdiction.
| If you… | Use… |
|---|---|
| Have a working US/EU card and want one model | OpenAI / Anthropic / Google direct |
| Have a working US/EU card and want many models | OpenRouter (card path) |
| Have a card but it fails Stripe | Stormfire (USDT) |
| Already hold USDT on Binance | Stormfire |
| Need a niche open-weight fine-tune | OpenRouter |
| Want pure open-weight inference at scale | Together AI or DeepInfra (if card works) |
| Are running a wrapper SaaS with thin margins | Stormfire (0% fee saves real money) |
| Want maximum observability | Helicone or PortKey on top of any of the above |
Every gateway in this guide claims OpenAI SDK compatibility. The level of compatibility varies. Stormfire and OpenRouter pass through the entire OpenAI surface (chat, embeddings, images, audio, tools, vision, structured outputs, streaming) and just route to the underlying provider. AIMLAPI is similar but occasionally lags on adopting new OpenAI parameters. Together AI and DeepInfra ship a partial OpenAI surface focused on chat completions and embeddings — vision and audio aren't always there.
If you're migrating from OpenAI direct, the gateways (Stormfire, OpenRouter) are the safest bet. Inference clouds need more code review.
This page is hosted on Stormfire's site, so naturally we recommend Stormfire when it fits. We tried not to recommend it in cases where it doesn't fit. If you're a US developer with a working card and you want to call OpenAI's API directly, just do that — using a gateway adds a hop you don't need. Gateways shine when you're routing across providers, when your card doesn't work, or when you're cost-sensitive on token spend at scale.
