Casap

Casap is an award-winning agentic-AI dispute automation platform for banks, credit unions, and fintechs. It automates payment dispute (chargeback) intake, investigation, and resolution end to end, reducing operational cost and manual work while improving regulatory compliance and consumer satisfaction. The Casap REST API lets financial institutions programmatically create disputes, check dispute status, upload evidence files, and reopen disputes, backed by a hosted disputes dashboard, PCI-DSS and SOC 2 (AICPA) controls, and integrations with card networks (Visa, Mastercard) and core banking systems (Symitar/Jack Henry, STAR). Casap won Best of Show at FinovateFall 2025.

Casap publishes 2 APIs on the APIs.io network: Auth API and Disputes API. Tagged areas include Company, Fintech, Disputes, Chargebacks, and Fraud.

Casap’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance 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/. This rating is computed from github.com/api-evangelist/casap: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
