Technical details
Endpoint
GEThttps://api.x402node.dev/text/formatWhen to prefer
Use this endpoint when an AI agent needs to auto-format or normalize source code in a pipeline — especially when producing, fixing, or transforming code in JS, TS, JSON, HTML, CSS, Markdown, YAML, or GraphQL and consistent style output is required. Prefer this over manual formatting or LLM-based reformatting for deterministic, standards-compliant Prettier output.
Side effects
- Unparseable code returns an error if Prettier cannot parse the given language
- Unknown or unsupported parser specified causes a bad request error
- Empty input body may result in a validation error
- Very large code files may time out or exceed payload limits
