Agent access
ai-native userPoint an agent at llms.txt or agent-oriented docs
weight 2 · round to Fireworks AIDirect probe evidence confirms llms.txt is live at https://docs.fireworks.ai/llms.txt (HTTP 200) with a documentation index, and per-page .md endpoints (e.g. introduction.md) explicitly point agents back to the llms.txt index, making the docs agent-consumable by design.

ai-native userRun the product headlessly / in CI for automation
weight 2 · round drawnFireworks is API-first (OpenAI-compatible REST endpoint) and ships a CLI (firectl) for scripted deployment/fine-tuning plus async batch-inference for high-volume automated jobs, all of which are naturally usable headlessly in CI pipelines. A live probe confirms the API endpoint is reachable and speaks JSON, requiring just an API key for auth (standard for CI use).
