Reviewer Notes

Nium has an OpenAPI spec and sandbox environment, which aids discoverability and testing, but lacks MCP server and llms.txt documentation. Account creation requires KYC verification and manual approval—highly unsuitable for autonomous agent signup. The API is reasonably structured but fintech-specific complexity and regulatory requirements limit practical agent autonomy; no free tier and mandatory credit evaluation create barriers to programmatic account bootstrapping.
