Response

Three changes in this release:

1. Exports can now stream large files instead of loading them in memory.

2. Two deprecated flags are gone; old config files still load with a warning.

3. Start-up is faster on big projects because plugins load on demand.

model: deepseek-v4-pro
tokens: 412 in · 236 out
cost: $0.0014
paid from: USDT balance

Example call with the official OpenAI Python SDK: 412 input and 236 output tokens on DeepSeek V4 Pro cost $0.0014 at our price of 23 October 2026.

What do you get with one API key?

One endpoint, one balance, every model.

The OpenAI format

Chat completions in the shape the OpenAI SDK, LangChain and most agent tools already speak.

12 open-weight models

DeepSeek, Qwen, gpt-oss, GLM, Llama, Gemma and Mistral, each under a licence that allows serving it.

Pay per token

No subscription and no seat fee: each call costs its input and output tokens at the model's price.

Prompts not stored

Once a response is sent, its text is gone; only token counts are logged, for 30 days.

Streaming and tools

Token-by-token streaming, tool calling and JSON output on the models that support them.

Crypto, no KYC

Top up in BTC, USDT, USDC, ETH, SOL, LTC. No ID, no selfie, no card, no work email.

Why is there no GPT, Claude or Gemini here?

Because their makers do not allow it. We do not sell access to GPT, Claude, Gemini or Grok: their makers forbid reselling API access without their approval, and we do not have it. Sites that sell those models far below list price for crypto often run on shared accounts or payment methods that are not theirs, and the guide on cheap API keys explains what that means for your data.

If you want ChatGPT, Claude or Cursor themselves, our dataset of 40 AI tools shows which ones accept crypto officially and which legitimate routes exist when they do not. The resale rules dataset quotes each provider's own terms.

How do I start?

Three steps. The only wait is the blockchain confirmation of your top-up.

Top up in crypto
Send at least $25 in USDT, USDC, BTC, ETH, SOL or LTC. No ID, no selfie, no documents.
Buy a credit pack
$25 of API credit for $25 or $50 of API credit for $50, paid from your balance. Your API key appears in the dashboard.
Point your SDK at us
Set the base URL to https://llmwithcrypto.com/api/v1 and pick a model id. The quick start has Python, Node.js and curl.

Quick answers before you buy

What is LLMwithCrypto?

An OpenAI-compatible LLM API for open-weight models, operated by SerpGoat LLC. You pay per token from a prepaid crypto balance, with no identity check.

Can I use the OpenAI Python or Node.js SDK?

Yes. The API speaks the OpenAI chat completions format: point the OpenAI SDK, LangChain or any OpenAI-compatible tool at our base URL with your key, and change the model name. The OpenAI-compatible API page lists what is supported and what is not.

How is a call billed?

You pay per token from your balance: input and output tokens are counted by the model’s own tokenizer and charged at that model’s price per 1M tokens. A call that ends in an error costs nothing. The pricing page shows a worked example.

Do you keep my prompts?

No. We do not store your prompts or the model’s answers: once a response is sent, its text is gone. Each call leaves one log line with the time, the account, the model and the token counts, deleted after 30 days.

Is there a free tier?

There is no free tier: the smallest credit pack is the way to try it, and unspent credit never expires.

Where is the service not available?

Not available to people or companies in Iran, North Korea, Cuba, Syria, Russia, Belarus or the occupied regions of Ukraine, because of sanctions.

Not sold	We do not sell access to GPT, Claude, Gemini or Grok: their makers forbid reselling API access without their approval, and we do not have it
KYC / ID verification	None — no ID, no selfie, no documents, no work email
Price	Each model costs 5% less than the median price of the public hosts that list it, for input and output tokens, read on 2026-10-23. Credit packs from $25
Billing	You pay per token from your balance: input and output tokens are counted by the model’s own tokenizer and charged at that model’s price per 1M tokens. A call that ends in an error costs nothing
Credit expiry	Credit has no expiry date: what you do not spend this month is still there next year
Compatibility	The API speaks the OpenAI chat completions format: point the OpenAI SDK, LangChain or any OpenAI-compatible tool at our base URL with your key, and change the model name
Features	Streaming works on every model; tool calling and JSON output follow what each model itself supports
Prompts and outputs	We do not store your prompts or the model’s answers: once a response is sent, its text is gone. Each call leaves one log line with the time, the account, the model and the token counts, deleted after 30 days. We never train or fine-tune any model on your prompts or outputs
Endpoint	`POST https://llmwithcrypto.com/api/v1/chat/completions`
Authentication	Pass your API key as a Bearer token in the Authorization header, as the OpenAI SDK does
Model licences	Each model keeps its own licence and use policy (for example Meta’s Llama Acceptable Use Policy and the “Built with Llama” notice); using a model through us means accepting them
Countries	Not available to people or companies in Iran, North Korea, Cuba, Syria, Russia, Belarus or the occupied regions of Ukraine, because of sanctions
Payment	Crypto only: BTC, USDT, USDC, ETH, SOL, LTC (USDT on TRC-20 or ERC-20, USDC on ERC-20)
Payment model	Top up from $25, then buy any credit pack from your balance. Credit on your balance does not expire and pays for tokens on any model, whenever you call the API. When a pack costs less than the minimum top-up, the part you paid only to reach that minimum comes back on request within 30 days of payment, in USDT or USDC, provided it is still unspent. The rest of a balance is not paid out unless the law requires it
Account	Sign in with an account number; an email address is optional. Your account number is how you sign in, so store it carefully. With an optional email on file you can recover it; with no email, a lost number is gone for good
Request logs	Each call leaves one log line: the time, the account, the model and the input and output token counts. Lines are deleted after 30 days. Prompts and answers are not kept. Account number, orders, top-ups and balance stay while the account exists, then only as long as accounting law asks. Authorities receive records only when a law compels us
Operator	SerpGoat LLC
Support	A person answers support emails within 12 hours, seven days a week, and helps you point your SDK or agent at the API
