The complete list of tracked coins (~18k) as {id, symbol, name}, paged: `page` + `perPage` (1-500, default 250). `includePlatforms: true` adds each coin's contract address per platform; `platform` (e.g. base, solana, ethereum) keeps only coins with a contract there; `symbol` keeps one ticker (exact, case-insensitive) across all its namesakes. For bulk id resolution, building a local symbol map, or enumerating every token on one chain; for a single lookup use coin-search.

Use this for high-volume narration, notifications and agent speech where the cost per call matters more than the timbre; use /api/tts or /api/tts-hd when it does not.
