Frequently Asked Questions

General

What is Flora API?
A comprehensive plant species database API covering 29,000+ US plants with detailed taxonomic, geographic, and ecological data. Access species information, county-level distribution, native/invasive status, and conservation data through simple REST endpoints.
Who is Flora API for?
Researchers, conservation organizations, government agencies, app developers, nurseries, and environmental consultants who need reliable plant data for biodiversity studies, restoration projects, plant identification apps, or land management.
What makes Flora API different?
County-level distribution data for precise geographic targeting, comprehensive native vs invasive classification, and conservation-focused datasets. Most competitors only offer state-level distribution or smaller species catalogs.

Pricing & Plans

How much does it cost?
  • Free: 1,000 requests/month for basic endpoints
  • Developer: $19/month for 7,500 requests with all features
  • Professional: $79/month for 75,000 requests with advanced analysis tools
  • Enterprise: Custom pricing for unlimited access
    • Can I try it before upgrading?
    Yes! Start with the free tier (no credit card required). Each tier includes a trial quota for accessing features available in the next tier up so you can test them out before deciding to upgrade.
    What happens if I exceed my rate limit?
    Requests will be temporarily blocked until the next minute/month period. Upgrade to a higher tier for increased limits, or contact us for custom Enterprise quotas.

    Getting Started

    How do I get an API key?
    Register at floraapi.com/register and you'll receive your API key immediately. You can then go to floraapi.com/dashboard to monitor your usage, access your API key if you forget it, or upgrade to a higher tier.
    Do I need to install anything?
    No installation required. Flora API is a REST API—just make HTTP requests with your API key. Works with any programming language or tool that supports HTTP.
    Where's the documentation?
    Interactive API docs at floraapi.com/docs with live examples. Each endpoint includes request/response schemas, parameter descriptions, and try-it-now functionality.

    Data & Features

    How many plant species are included?
    29,000+ species covering native, introduced, invasive, and cultivated plants across the United States.
    Where does the data come from?
    Authoritative sources including USDA PLANTS Database, BONAP, and Lady Bird Johnson Wildflower Center. Data is updated annually to maintain accuracy.
    What data is restricted to paid tiers?
    County-level distribution, conservation status, climate projections, plant identification, and edible/medicinal plant data are available in the Developer tier ($19/month). Advanced climate analysis reports, bulk export, and invasive alerts require the Professional tier. Basic species search and regional data are accessible in the free tier.
    Can I download the entire database?
    Unfortunately, no. Bulk exports are available (Professional tier) but limited to 100 species per call with filters. Premium data like county distribution is excluded to protect our competitive advantage. Contact us for Enterprise licensing if you need complete data access.

    Technical

    What authentication method do you use?
    API key authentication via Bearer token in the Authorization header. Magic link email login for dashboard access—no passwords needed.
    What's the response format?
