Or pay as you go — no subscription
Code questions come in bursts: a flurry during design, then nothing for months. Buy credits once and spend them when a project needs them. They never expire.
A quick answer costs 1 credit and a library search 1; a deeper review costs 10 and an expert analysis 30. Reading the code library is always free. If you ask every month, a plan is the better rate — about $0.15 a credit on Starter.
For software companies and AI assistants
Put California local ordinance search inside your own product, or use the code library from your AI assistant.
