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, Artificial Intelligence, 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 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/paid: open an issue to ask a question, or submit a pull request to add artifacts.
