# AELDER

> OpenAI-compatible access to leading AI models, with savings of up to 92% compared with official API prices, first-top-up bonuses and pay-per-token billing without a subscription.

Launch status: API access is coming soon. Sign-in, registration, top-ups and API requests are not available yet. The catalog and documentation describe the planned service.

AELDER is for developers, AI-agent builders, enthusiasts and small teams. Access GPT, Claude, Gemini, DeepSeek and other model families through one API key and one prepaid balance.

Key benefits:
- Savings of up to 92%; the exact saving depends on the model and input, cached input and output usage.
- A matching bonus on the first top-up, up to $20 extra.
- Additional bonuses of 5% from $20, 10% from $50, and 15% from $100. These stack with the first-top-up bonus.
- On a first top-up, pay $20 and receive $41 in service credit, or pay $50 and receive $75.
- Start with $5, paid in USDC. No subscription or mandatory monthly fee.
- Discounted cached input for repeated context.

Connect an OpenAI-compatible SDK, coding tool or AI agent by setting the service's base URL and your API key where custom endpoints are supported. The API supports streaming, tool calls and an Anthropic-compatible /v1/messages endpoint. See the integration guidance for setup details.
