Translation APIs pricing
Translation APIs split into two camps: raw machine-translation engines you call per character (DeepL, Google, AWS, Azure, Lara) and localization platforms that wrap MT in TMS workflows, glossaries and connectors (Lokalise, Lilt). For a developer or AI agent picking an engine, the things that actually differ are self-serve signup and free allowance, documentation depth, SDK language coverage, and the reliability backing (published SLA + status history). The hyperscalers win on reliability and SDK breadth; DeepL and Lara lead on translation quality and clean docs; the platform players (Lokalise, Lilt) are sales-led and aimed at localization teams rather than per-call API consumers.
