AMG Funds Data API

Undocumented, anonymously callable JSON API on wealth.amg.com that backs the AMG Wealth Platform product pages. Exposed as the AMG-authored WordPress REST namespace amgfundsdata/v1, whose route table the site itself publishes. Sixteen routes serve AMG Funds product, performance and portfolio data: /products/funds, /products-data and /products-table return structured fund rows with ticker, fund id, asset class, NAV, trailing performance and Morningstar rating, while the fund-detail, quickview, spotlight and style-box routes return pre-rendered HTML fragments. AMG publishes no developer portal, reference, OpenAPI or terms for programmatic use; the OpenAPI referenced here was derived by API Evangelist from the provider's own route table plus live responses observed 2026-08-30.

Where this information came from

This is an independent, third-party profile of AMG Funds Data API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
