RealDentalCosts::API - Client for the Real Dental Costs open data API


code

=begin code :lang<raku>

use RealDentalCosts::API;

my %crown = procedure('dental-crown');
say %crown<national><low_usd>;

my %medicaid = medicaid('D3330');
say %medicaid<meta><license>;

=end code


A minimal, dependency-light HTTP client for the free, no-key JSON API
published by Real Dental Costs (L<https://realdentalcosts.com/en/api/>):
U.S. dental procedure price benchmarks by state, and Medicaid (T-MSIS)
provider payment data by CDT procedure code.


Data is licensed CC BY 4.0 by the Real Dental Costs Data & Research Team.
Every response carries a C<meta> block with the license, DOI, and
methodology link — see L<https://realdentalcosts.com/en/methodology/>.


This module shells out to C<curl> rather than depending on a full HTTP
client stack, keeping the dependency footprint to just C<JSON::Fast>.
