Market Opportunity
Agent-aware API billing — metered micro-payments for autonomous agents targets a $22.5B = 2.5M developer orgs x $9K ACV (API platform + usage + infra per year) total addressable market with medium saturation and a year-over-year growth rate of 30-45% (API platforms + agent tooling growth).
Key trends driving demand: Autonomous agents -- agents increasingly orchestrate tools and will pay for specialized API calls directly, creating steady programmatic demand.; Usage-based pricing -- customers favor consumption models for fairness and flexibility, enabling per-call revenue streams tied to actual value delivered.; Micropayment primitives -- improved off-chain and pooled settlement reduces per-transaction costs, making tiny per-call charges economically viable.; API-first infrastructure -- standardization around API contracts and discovery makes it easy for agents to find and call specialized services..
