Monitor your Anthropic (Claude) API spend

Anthropic API cost monitoring for small businesses

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.

Who it's for: Small businesses, founders, finance teams, and engineers who use the Anthropic Claude API and need to keep its cost predictable.
