## 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 ca-prop-65-safe-harbor-warning-validator-8c52b846
```

Example prompt: What's the correct 2025/2026 Prop 65 short-form warning template and NSRL threshold for phthalates on a consumer product, including the symbol rules and 60-day-notice checklist?

## When to prefer this

Choose this endpoint when you need structured, ready-to-use Prop 65 warning language, threshold references, and compliance checklists for a specific chemical class and exposure route — especially when building ecommerce compliance workflows, label generation pipelines, or 60-day-notice defense documentation. It is more focused and actionable than a generic legal database search and covers the 2025/2026 short-form rule updates specifically.

## Known failure modes

- Missing required chemical_class parameter returns a validation error
- Unsupported chemical_class value (outside enum) returns a 400 or schema error
- Unsupported exposure_route value returns a 400 validation error
- Service unavailable or timeout on fly.dev host
- Payment failure via x402 protocol prevents access

## How this service works

California Prop 65 safe-harbor warning validator & 2025/2026 short-form chemical-naming rules. Pass ?chemical_class=phthalates|lead|bpa|acrylamide|cadmium (default phthalates) & optional ?exposure_route=consumer_product|food|apparel. Returns short-form/long-form templates, NSRL/MADL thresholds, symbol rules, and 60-day-notice defense checklist. Educational reference only; not legal advice.

## Output

Returns a structured payload including: the updated 2025/2026 short-form warning template, the long-form warning template, symbol requirement details, NSRL or MADL reference threshold, a representative chemical example and CAS number, endpoint toxicity classifications, common products affected, short-form rule update notes for 2025/2026, and a 60-day-notice defense operations checklist — plus a disclaimer that the output is educational only and not legal advice.
