How this service works

Pay-per-request LLM inference for AI agents. OpenAI-compatible, paid in USDC via x402.

Output

Returns an OpenAI-compatible chat.completion JSON object containing the assistant's reply text, finish reason (e.g. 'stop'), and token usage statistics (prompt tokens, completion tokens, total tokens), along with the model name and a unique completion ID.

Example use cases

Autonomous agent reasoning loop

“I need my agent to think through a multi-step plan — send this message thread to the GLM-5.3-Flash model on OpenRelay with a system prompt of 'You are a reasoning assistant' and limit the response to 300 tokens so I keep costs down.”

Cost-controlled content summarization

“Summarize this article using the DeepSeek-V4-Flash-0731 model on OpenRelay: cap it at 150 tokens and use a temperature of 0.3 for a factual, concise result.”

On-demand chatbot backend for a dApp

“Route this user's question to the MiniMax-M2.7 model via OpenRelay — the message is 'How do I stake my tokens?', system role is 'You are a DeFi support agent', and stream the response back to me.”

When to prefer

Choose OpenRelay when you need OpenAI-SDK-compatible LLM inference with no subscription or API key setup — just pay per call in USDC via the x402 protocol. Ideal for autonomous AI agents that need to self-fund inference, for developers who want cost-controlled pay-as-you-go access to models like GLM-5.3-Flash, DeepSeek-V4-Flash, or MiniMax-M2.7 without committing to a monthly plan, or for Web3-native applications where crypto micropayments are the preferred billing mechanism.
