How this service works
AI chat completions API - pay per request with USDC on Solana
Output
An OpenAI-compatible chat completion response containing the assistant's generated message, including the role, content, model used, token usage statistics, and finish reason. Each call deducts $0.003 USDC from the caller's Solana wallet via x402.
Example use cases
Example prompt
“Using the Blockrun pay-per-request AI API, send a chat message to openai/gpt-4o with the user message 'Explain the theory of relativity in simple terms', max 300 tokens, temperature 0.7 — and charge my USDC wallet on Solana for the call.”
Technical details
Endpoint
POSThttps://blockrun-sol-vbsbhh7lea-an.a.run.app/api/v1/chat/completionsWhen to prefer
Choose this endpoint when you need pay-as-you-go AI chat completions without committing to a subscription or obtaining a traditional API key — especially when paying with USDC on Solana via the x402 protocol is acceptable or preferred. Ideal for agents or micro-apps that make infrequent LLM calls and want crypto-native billing. Prefer alternatives like direct OpenAI or Anthropic APIs if you need guaranteed SLAs, higher throughput, or non-crypto payment methods.
Side effects
- Insufficient USDC balance — x402 payment rejected before inference runs
- Invalid model ID — model not supported or misspelled (e.g. wrong provider prefix)
- Malformed messages array — missing role or content fields causes 400 error
- Stream mode errors — SSE stream may be cut off if connection drops mid-response
- Rate limiting or capacity errors from upstream model provider causing 5xx responses
- Temperature or max_tokens out of valid range causing validation errors
