Example use cases
Example prompt
“Using the blockrun.ai chat completions API on Solana, send this conversation to openai/gpt-4o with temperature 0.7 and max 500 tokens — messages: system 'You are a helpful assistant', user 'Explain quantum entanglement in simple terms' — and pay the $0.001 USDC fee per request.”
Technical details
Endpoint
POSThttps://sol.blockrun.ai/api/v1/chat/completionsWhen to prefer
Choose this endpoint when you need pay-per-call LLM access billed in USDC on Solana without a subscription, especially in web3 or agentic workflows that already hold Solana-based stablecoins. Ideal for low-frequency or bursty AI calls where per-request micropayment is preferable to a monthly API key billing model.
Side effects
- Insufficient USDC balance on Solana wallet — payment fails with 402 status
- Invalid or unsupported model ID — returns error indicating model not found
- Malformed messages array (missing role or content) — returns validation error
- Exceeded max_tokens limit for the selected model — truncated response or error
- Network/RPC issues on Solana causing payment verification delays — timeout or retry needed
- Stream mode connection drop — partial response received
