Technical details
Endpoint
POSThttps://blockrun-sol-vbsbhh7lea-uc.a.run.app/api/v1/chat/completionsWhen to prefer
Choose this endpoint when you need AI chat completions with crypto-native, pay-per-request billing using USDC on Solana — ideal for agents or apps that want to avoid subscription fees and pay on-chain via x402. Prefer over traditional OpenAI API when the use case requires decentralized, per-call micropayments without API key management.
Side effects
- Insufficient USDC balance or failed x402 payment — payment required/declined error
- Invalid model ID — model not found or not supported
- Malformed messages array — missing role or content fields
- Exceeding token limits — max_tokens too high for the selected model
- Network or cloud run timeout — service unavailable or 5xx error
- Stream mode errors if streaming is not supported or connection drops mid-response
