Adopets

Adopets is an Adoption Management System (AMS) for animal shelters and rescues that streamlines the entire pet adoption process — online and in-person applications, approval and team collaboration workflows, digital kennel cards with QR codes, secure payment processing for adoption fees, licenses, products and donations, daily reporting and dashboards, and post-adoption communication. Backed by Techstars. Adopets exposes an External API (documented as a public Postman collection) that lets partner systems connect staff users and create, retrieve, change, cancel, and refund adoption payment requests and transactions on behalf of an organization, authenticated with an organization API key plus a per-session JWT bearer token.

Adopets publishes 3 APIs on the APIs.io network: payment-request API, payment-transaction API, and system-auth API. Tagged areas include Pet Adoption, Animal Welfare, Shelters and Rescues, Adoption Management, and Payments.

Adopets’ developer surface includes documentation, API reference, authentication, sandbox, and 17 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/.
