Cosmetic ingredient API comparison

INCIDecoder API alternative for developers

If you need a documented API rather than a consumer website, Dermalytics provides authenticated REST endpoints, a machine-readable OpenAPI contract, a hosted MCP server, and JavaScript and Python SDKs. INCIDecoder remains a useful public website for reading ingredient and product explanations.

Is there a public INCIDecoder API?

In a review of INCIDecoder's public website on July 20, 2026, we found its web ingredient decoder and educational pages, but did not find public REST, authentication, OpenAPI, SDK, or pricing documentation for developers. That does not prove private access is unavailable; contact INCIDecoder directly if you need an authoritative answer about private or future access.

Choose INCIDecoder when…

  • You want to inspect ingredients interactively in a ready-made website.
  • You want consumer-readable ingredient and product explanations.
  • You do not need a documented integration contract.

  • You need authenticated JSON, match status, identifiers, and structured scores.
  • You need OpenAPI, SDKs, or MCP tools for an agent workflow.

What does the API return?

Dermalytics exposes one endpoint for a single normalized ingredient and another for a complete ingredient list. Responses can include canonical names, synonyms, CAS/EC identifiers, cosmetic functions, nullable 0–5 comedogenicity and irritancy fields, match status, and remaining credits. Check the live contract before integration because response fields can evolve.

curl "https://api.dermalytics.dev/v1/ingredients/niacinamide" \
  -H "Authorization: Bearer YOUR_API_KEY"

Test with your own ingredient list

Start with a representative product label, verify the matches and null fields, and decide how your application will present uncertainty before scaling to a catalogue. Ingredient data supports product features; it is not a medical diagnosis.
