Developer Tools / API / Observability
Marginal is an LLM cost-tracking and observability product that attributes spend by customer, feature, model, or any custom field. The page shows a dashboard, pricing logic, SDKs, HTTP API access, and example integrations for TypeScript and Python.
The page clearly describes a real AI developer product with a focused use case: tracking and slicing LLM spend. It includes enough public evidence for a directory listing, including product purpose, dashboard behavior, SDKs, HTTP API, code examples, and documentation links. The offering is specific and useful for teams building with LLM APIs.
The crawl shows strong product detail, but it does not reveal pricing, account requirements, supported providers beyond the examples, or whether there are alerts, exports, or team features outside the dashboard shown.
