About Costiva

Costiva is a web app that monitors Anthropic (Claude) API spend and usage for small businesses.

What we do

Costiva is a web application that helps small businesses monitor and understand their Anthropic (Claude) API spending. You connect Costiva to your Anthropic organization with a read-only Admin API key, and it ingests your usage and cost data through Anthropic's Admin Usage & Cost API. From there, Costiva shows what you are spending, which Claude models and workspaces drive that spend, your cost per token, your rate-limit usage, and your Claude Code analytics. Costiva also lets you attribute cost to the APIs and AI agents you run, tie that spending to business hypotheses and the KPIs you define, and measure return on investment by comparing cost against outcomes. It is built for founders, finance teams, and engineers at small companies who need to keep Claude API costs predictable without building their own reporting. Costiva is a multi-tenant SaaS: each organization's data is isolated, access is protected with optional SMS two-factor authentication, and teams can invite multiple members. The goal is simple: make Anthropic API cost visible, attributable, and tied to results, so spend stays under control as your use of Claude grows.

The problem we solve

As small businesses adopt the Claude API, spend can grow faster than visibility into it. Costiva exists to make Anthropic API cost visible, attributable, and tied to results — so teams can keep it predictable as their use of Claude grows.

How it works

Costiva connects to your Anthropic organization using a read-only Admin API key and reads your data through Anthropic's Admin Usage & Cost API. It does not require code changes to your application.
