Their basic unsupported tier (up to 1 query/sec on avg) is free. You have to contact them if you want pricing for a supported plan. This type of opaque pricing normally annoys me, but they were recently acquired by Google so I expect the pricing to eventually become more transparent and most likely be fairly reasonable. https://api.ai/blog/2016/09/19/api-ai-joining-google/ https://api.ai/blog/2016/09/19/api-ai-joining-google/
