## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitecheck-health-travel-cosing-inci-ingredient-lookup-e6474248
```

Example prompt: Can you look up niacinamide in the EU CosIng ingredient database and tell me its cosmetic functions, CAS number, EC number, and CosIng ID?

## When to prefer this

Use this endpoint when you need authoritative EU CosIng regulatory data for cosmetic ingredients — specifically INCI-aligned identifiers (CAS, EC, CosIng ID) and official EU cosmetic function classifications. Prefer this over general chemistry databases (like PubChem) when the context is cosmetic regulation or EU compliance. Note: this does not include US CIR safety assessments or EU restriction details; use a separate eu-cosing-cosmetics endpoint for restrictions.

## Known failure modes

- Ingredient name not found in CosIng — returns empty results or error if no match exists
- Misspelled or non-standard INCI name yields no results
- Limit parameter out of range (must be 1–25) causes a validation error
- CosIng upstream database unavailable causes timeout or 5xx error
- Common name used instead of INCI name may return no matches if not indexed

## How this service works

Cosmetic ingredient lookup by INCI name: INCI name, cosmetic functions (e.g. skin conditioning, preservative), chemical description, CAS and EC numbers and CosIng ID, from the European Commission's CosIng ingredient inventory (the EU's INCI reference). Safety assessments of the US Personal Care Products Council (CIR) are not included; use eu-cosing-cosmetics for EU restrictions.

## Output

Returns a list of matching cosmetic ingredients from the EU CosIng database, each including the official INCI name, CosIng ID, CAS number, EC number, chemical description, and a list of cosmetic function classifications (e.g. skin conditioning, preservative, emollient).
