# Federal Trade Commission

> The Federal Trade Commission (FTC) is the U.S. federal agency that enforces antitrust
> and consumer protection law. It operates one small public, read-only REST API at
> https://api.ftc.gov/v0 covering Do Not Call complaint reports and Hart-Scott-Rodino
> early termination notices, plus a Project Open Data (DCAT-US 1.1) inventory of 95
> datasets at https://www.ftc.gov/data.json. Its two other developer-facing programmes —
> the National Do Not Call Registry telemarketer download and the Consumer Sentinel
> Network — are gated behind registration and law-enforcement vetting and publish no
> public contract.

## What the FTC does not publish

Recorded so an agent does not waste calls looking: no OpenAPI, GraphQL, AsyncAPI, gRPC or
WSDL description; no webhooks or event stream; no MCP server; no A2A agent card; no
/.well-known documents of any kind (security.txt, api-catalog, openid-configuration all
404 or soft-404 as of 2026-09-09); no SDKs or CLI in any package registry; no changelog,
status page, SLA or deprecation policy; no pricing, because access is free.
