- Do you train on my prompts?
- No. We forward your prompt only to the AI provider you select to generate the response. We don't store it beyond the request, and we don't share it with anyone else.
- What about "free" models?
- We don't ship free models that require sharing your data with the upstream provider. If a free tier's terms allow training on user prompts, we don't list it.
- How is this different from OpenRouter or Portkey?
- Pay-per-call USDC on Base or Solana via x402. No account, no API key, no subscription. Auto-fallback when a model is down. SDKs are OpenAI-compatible.
- Why USDC instead of a subscription?
- Agents can hold USDC; agents can't hold a credit card. Settlement happens on-chain in the same request via the x402 protocol — no prepaid credits, no minimum spend.
- What happens if a model is down?
- We auto-fallback to a comparable model and surface which one served you via the X-Fallback-Model response header, so your application never sees a hard failure.
- Are the SDKs OpenAI-compatible?
- Yes. Change base_url and you're done — every endpoint matches OpenAI's shape. @blockrun/llm for TypeScript, blockrun-llm for Python, both MIT-licensed.
- Can I use this in production?
- Yes. We run on Base mainnet with 1M+ calls per month. Use testnet.blockrun.ai for development against Base Sepolia.
