How this service works
Official drinking-water file for an address or lat/lng (relocation / lodging due diligence). clear/caution/avoid from EPA, Hub'Eau, or JMP. Never invents grades.
Output
Returns a structured response containing a safety grade (clear, caution, or avoid), the underlying data source (EPA, Hub'Eau, or JMP), and location details for the queried address or coordinates. The service never invents or interpolates grades — if no official data exists for the location, it returns a no-data response rather than a fabricated result.
Example use cases
Apartment relocation due diligence
“I'm about to sign a lease at 88 Bleecker Street, New York, NY 10012 — can you check the official tap water safety grade for that address before I commit?”
International travel lodging check
“I'm staying at a hotel near 48.8566° N, 2.3522° E in Paris — is the tap water there officially rated safe to drink, and what source is that grade from?”
Short-term rental host compliance
“Can you pull the drinking water quality grade for 1200 Ocean Drive, Miami Beach, FL 33139 so I can include it in my Airbnb listing for guests?”

Endpoint
GEThttps://zini-x402.wouldzini.workers.dev/v1/lookupWhen to prefer
Choose this endpoint when you need an authoritative, source-cited drinking water safety assessment for a specific address or GPS coordinates — especially for relocation, lodging, or real estate due diligence workflows where data provenance matters and hallucinated grades are unacceptable. It covers international locations via JMP and Hub'Eau in addition to US EPA data, making it more broadly applicable than US-only water quality tools.
Side effects
- Address not found or geocoding failure — returns an error indicating the location could not be resolved
- No official data available for the region — returns a no-data response rather than a fabricated grade
- Invalid coordinate pair (lat without lng or vice versa) — returns a validation error
- Ambiguous address with multiple matches — may return an error or prompt for clarification
- Payment failure (x402) — call is rejected before data is returned
