A fully-generated, strongly-typed Go client for the Telegram Bot API. * 176 methods + 301 types generated from Bot API v10.0 * 1408 auto-generated tests (8 scenarios per method) * Typed unions throughout — no 'any' in the public surface * Pluggable HTTP transport and JSON codec (default goccy/go-json) * Built-in retry middleware honouring Telegram's retry_after * Generic dispatcher with filters and conversation handlers * Self-verifying codegen pipeline (regen → audit → emit → run tests) * 14 example bots covering common patterns
