Aon

Aon plc is a London-headquartered global professional services firm delivering integrated risk and human capital advisory through two reporting pillars — Risk Capital (broking, reinsurance, risk analytics) and Human Capital (health, wealth, talent, rewards). The firm operates in over 120 countries, lists on the NYSE under the ticker AON, and grew its US middle-market footprint with the April 2024 acquisition of NFP for roughly $13B. Aon publishes named analytics platforms (Risk Analyzer suite, ReMetrica, CyQu, Spectrum, Impact Forecasting catastrophe models, Radford McLagan Compensation Database, SkillsGraph, Gauge, Revenue GPS) but those tools are delivered through gated client portals — no developer portal, OpenAPI catalog, SDK org, or public API reference is published on aon.com.

Aon publishes 1 API on the APIs.io network. Tagged areas include Risk, Reinsurance, Insurance, Health, and Retirement.

Aon’s developer surface includes YouTube channel and 16 more developer resources.
