> ## Documentation Index > Fetch the complete documentation index at: https://docs.photon.codes/docs/llms.txt > Use this file to discover all available pages before exploring further. > ## Agent Instructions > Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code. > Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer. > For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them. > The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes. # List number area codes > Lists current provider coverage for US local numbers, sorted and deduplicated.
