AMG Corporate Content API

Undocumented, anonymously callable JSON API on www.amg.com that backs the AMG Affiliate directory. Exposed as the AMG-authored WordPress REST namespace amginc/v1. A single POST-only route, /amginc/v1/affiliates, takes no arguments and returns the full roster of independent investment management firms AMG holds a stake in, each with its logo, founding year, the year it became an AMG Affiliate, and its page on amg.com. AMG publishes no developer program covering it; the OpenAPI referenced here was derived by API Evangelist from the provider's own route table plus a live response observed 2026-08-30.

Where this information came from

This is an independent, third-party profile of AMG Corporate Content 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.
