Frequently Asked Questions

Everything you need to know about CallAI integration and payments

How do I access Claude 3.7 Sonnet, DeepSeek R1, and GPT-4o without a credit card?

Register for a CallAI account to receive an API key. Fund your wallet starting from $1 using on-chain TRON USDT-TRC20. Configure your client (OpenAI SDK, Cursor, or Cline) to use our Base URL (https://api.callaiapi.com/v1). No credit card or identity verification is required.

Is the API 100% compatible with the official OpenAI SDK?

Yes. CallAI implements the standard OpenAI v1 specification (/v1/chat/completions and /v1/embeddings). In any Python, Node.js, or Go application using the official OpenAI client, simply point base_url to https://api.callaiapi.com/v1 and pass your CallAI API key.

How does billing work? What are the fees?

We use pure pay-as-you-go billing with no monthly subscriptions or platform fees. Prices equal upstream benchmark costs multiplied by 1.10. Billing is tracked down to 6 decimal places ($0.000001) in an immutable PostgreSQL ledger. Client stream disconnects are metered strictly up to the last delivered chunk.

How do I configure CallAI in Cursor or Windsurf IDE?

In Cursor, go to Settings > Models. Enable "Override OpenAI Base URL" and enter https://api.callaiapi.com/v1. Enter your CallAI API key in the API Key field, and add your desired model IDs (such as claude-3-7-sonnet or deepseek-r1).

What are the DataForSEO and cloud server integrations?

Your wallet balance is shared across all services. You can query DataForSEO Google/Bing SERP APIs (where result polling via task_get is completely free of charge) and provision automated Vultr / DigitalOcean VPS instances with automated cloud-init setup and a 25-minute watchdog refund policy.
