How this service works
OpenRelay is a pay-per-request LLM inference relay. Autonomous AI agents call our OpenAI-compatible endpoints and pay in USDC via x402 — no API keys, no signup, no subscriptions. Backed by DeepSeek V4 Flash (400k ctx), Kimi K2.6 (240k ctx), and MiniMax M2.7 (180k ctx). Price: $0.10 per 1M tokens (input + max_tokens). USDC on Solana or Base. Facilitator: PayAI (gasless).
Output
Returns an OpenAI-compatible chat.completion JSON object containing the assistant's reply text, token usage breakdown (prompt, completion, total), model ID used, a unique completion ID, finish reason (e.g. 'stop'), and creation timestamp.
Example use cases
Autonomous agent reasoning loop
“Run this multi-turn conversation through the DeepSeek V4 Flash model: system says 'You are a research assistant', then the user asks 'What are the main causes of the 2008 financial crisis?' — give me up to 800 tokens back, temperature 0.5.”
Crypto-native app content generation
“I'm building a dApp and need to generate marketing copy without setting up a subscription — send this to the Kimi K2.6 model: system 'You are a copywriter', user 'Write a punchy one-paragraph description of a DeFi yield optimizer', max 256 tokens.”
Long-context document summarization
“Use the MiniMax M2.7 model to summarize this 50,000-word legal document I'm pasting — fit it in under 1000 tokens output, temperature 0.3, and pay per request so I'm not locked into a plan.”
Technical details
Endpoint
POSThttps://openrelay.hggfffdfy687.workers.dev/v1/premium/completionsWhen to prefer
Choose this endpoint when an autonomous AI agent needs LLM inference without pre-registered API keys or subscriptions, and can pay per request in USDC on Solana or Base via x402. Ideal for crypto-native or agent-to-agent workflows where programmatic micropayments are preferred over OAuth or API key management. Prefer over standard OpenAI when you want pay-as-you-go stablecoin billing, access to DeepSeek V4 Flash (400k context), Kimi K2.6 (240k context), or MiniMax M2.7 (180k context) under a single OpenAI-compatible interface.
Side effects
- Insufficient USDC balance or failed x402 payment returns 402 Payment Required
- Invalid or unsupported model ID returns 400 Bad Request
- max_tokens exceeds model's context limit returns 400 validation error
- Malformed messages array (missing role or content) returns 400
- Upstream model provider timeout may return 503 or 504
- Temperature out of range (>2 or <0) returns 400 validation error
