Paid

Paid (paid.ai) is the monetization platform for AI agents. It gives teams that build and sell AI agents the pricing, billing, and margin infrastructure to charge with flexible models — credits, usage-based, seat-based, and outcome-based pricing — while tracking the AI costs and delivered value behind every customer. Paid exposes a REST API (v1 and v2 on api.agentpaid.io), first-party SDKs for Node, Python, Go, and Java, a CLI, embeddable UI components, billing webhooks, an agent skill, and a hosted MCP server. Backed by EQT Ventures, Lightspeed Venture Partners, Seedcamp, and Techstars.

Paid publishes 22 APIs on the APIs.io network, including agents API, analyticsExperimental API, checkouts API, and 19 more. Tagged areas include Company, AI, Billing, Monetization, and Payments.

The Paid catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Paid’s developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, engineering blog, authentication, and 21 more developer resources.
