Free API for ad calculators and compliance checks

The formulas behind our free calculators and the deterministic health ad compliance check, as a JSON API. No key, no AI, no cost.

Base URL https://telehealthmedia.com/api/v1/. Every endpoint takes a JSON body with POST. The full description is in OpenAPI 3.1.

Example

curl -X POST https://telehealthmedia.com/api/v1/check_ad_compliance \
  -H 'Content-Type: application/json' \
  -d '{"text": "Same as Ozempic, for less", "vertical": "glp1"}'

Responses are { "result": ..., "source": "From Telehealth Media's free tools: <tool page>" }. Please show the source link wherever you display a result.

Limits

60 requests per IP per hour. Over the limit returns 429 with Retry-After.
Request bodies up to 32 KB. CORS is open, so you can call it from a browser.
Inputs are not stored. Logs hold the endpoint name and time only.
Compliance results are heuristics about review risk, not legal advice.

For writing tools (hooks, scripts, batch plans), use the MCP server. The formulas are also an npm package and the rules ship as a CLI; see our open-source projects once published.
