# Verizon

> Verizon Communications is a US telecommunications carrier whose developer surface spans three
> distinct properties: ThingSpace (IoT connectivity management, device diagnostics, location,
> software management), the developers.verizon.com API Marketplace (TM Forum-aligned service
> management, private IP and secure cloud interconnect APIs for enterprise network customers), and
> the 5G Edge portal (mobile edge compute discovery). Access is enterprise-contracted; there is no
> public self-serve pricing. Verizon publishes no OpenAPI, no AsyncAPI, no /.well-known/ discovery
> document, no MCP server and no agent card. It does publish a rich webhook (callback) catalogue,
> a detailed error-code registry and a two-token OAuth model.

Verizon does not publish an llms.txt of its own: https://developers.verizon.com/llms.txt returns
HTTP 200 with the React SPA shell (an unmatched-path catch-all), not an llms.txt document.
