Define whether you locate, order, or coordinate care
Decide whether your product locates collection sites, sells a test, or coordinates clinical care. These roles carry different requirements. A locator should identify network coverage and send a person to the correct booking or ordering experience.
Return locations with enough context for a handoff
Accept city, country, postal code, or coordinates; use a sensible radius; and return address, distance, phone, hours where available, and booking URL. Keep provider and source timestamps with each result, because location inventory changes.
Pair the locator with the next data step: after testing, make it easy to import the report, establish the date and units, and compare it with prior results. Do not collect more location precision than the task needs.
Input and result design
Accept postal code, city, country, or latitude and longitude with a radius and provider filter. Normalize the query through a geocoder with clear jurisdiction and rate limits. Return the interpreted location so users can spot a bad match.
Each result should include stable ID, name, address, coordinates, distance, provider network, contact or booking URL, accessibility fields where available, source, and last-updated time. Avoid claiming that a test is available unless the upstream service confirms it.
Public map and live API architecture
A static public snapshot supports anonymous browsing, fast rendering, and search indexing. The authenticated API can provide current network handoffs and richer filtering. Label the snapshot date and route users to current provider confirmation.
Cache location searches carefully and avoid storing precise user location without a defined need and consent. Use coarse analytics where possible. Rate-limit public geocoding and protect provider credentials on the server.

Locator API test matrix
- Ambiguous cities and postcodes return understandable choices
- No-result states suggest a wider radius or another modality
- Distances and units match locale
- Genetics headquarters cannot be mistaken for a draw site
- Public credentials never reach the browser
- Users are told to verify current service details
Use the unified provider-discovery model
WellNizz's provider discovery combines WGS and genetic-testing options with nearby Quest and SYNLAB lab draw-site handoffs. The single-modality lab search is available to authorized users and supported as a low-cost x402 route for agent-friendly pay-per-request discovery.
Verify live availability at booking time
A location result does not confirm test availability, eligibility, price, or medical appropriateness. Users must confirm current details directly with the lab network or ordering service.

FAQ
What input does a lab locator API need?
A postcode, city/country, or latitude and longitude plus an optional radius is typically enough to search nearby covered locations.
Can a lab locator API book an appointment?
It can return a booking handoff when the provider supports one. Actual booking rules depend on the lab network and ordering flow.
