APIs, integrations and developer platforms.
API and integrations developers connect systems: they design endpoints, read other vendors' documentation, wire up webhooks, handle authentication and debug failing requests. AI tools fall into two groups, model APIs you build on (Replicate, Stable Diffusion API, Novita AI) and helpers for the work itself, such as scrapers, no-code connectors like Albato and data tools like JSON AI. Check rate limits, uptime and how stable the API contract is.
An AI app gives people a finished interface, while an AI API exposes the model to your own code through requests and responses. Replicate and Stable Diffusion API are examples of the second kind. APIs give you control and automation, but you handle errors, limits and billing logic yourself.
Compare output quality on your own inputs first, then look at latency, rate limits, SDK support, data retention policy and how often models are deprecated. A hosted marketplace such as Replicate lets you swap models behind one interface, which reduces lock-in if a provider changes terms.
It can draft client code, translate between formats and explain error messages, but it often invents endpoints or parameters. Always check generated calls against the vendor's real documentation and test in a sandbox before connecting anything to production data or payments.
