Example use cases
Autonomous agent LLM calls with micropayments
“I want my agent to call DeepSeek-V4-Flash through OpenRelay's premium tier with the system message 'You are a coding assistant' and the user message 'Write a Python function to parse JSON from a URL', capping the response at 1024 tokens.”
Multi-turn customer support chatbot
“Send this three-turn conversation to the OpenRelay premium endpoint using DeepSeek — the system says 'You are a friendly customer support agent', user asks 'How do I reset my password?', assistant replied 'Click Forgot Password', now the user is asking 'I don't see that option' — get the next assistant reply with temperature 0.5 and max 300 tokens.”
Low-cost on-demand content drafting
“Use OpenRelay's premium chat API to draft a short product description: system prompt 'You are a marketing copywriter', user message 'Write a 2-sentence description for a noise-cancelling Bluetooth headset targeting remote workers', temperature 0.9, max 256 tokens.”

Endpoint
POSThttps://openrelay.hggfffdfy687.workers.dev/v1/premium/chat/completionsWhen to prefer
Choose this endpoint when you need OpenAI-compatible chat completions billed per request via x402 USDC micropayments, especially for autonomous agents that lack a subscription and want access to DeepSeek or other models without upfront commitment. Prefer this over the standard OpenRelay chat endpoint when the premium tier's pricing tier or model availability is needed.
