RCP API Reference: Accessing the Framework Programmatically

The RCP REST API endpoint allows software developers, ESG platforms, and job management systems to programmatically access the full Restoration Carbon Protocol framework — all articles, emission factors, schema documentation, and article relationships — without scraping the site. This endpoint is part of the Tygart Media REST API and is publicly accessible without authentication.

Base URL: https://tygartmedia.com/wp-json/tygart/v1/rcp

Endpoints

GET /wp-json/tygart/v1/rcp

Returns the complete RCP framework index: all published articles with metadata, their relationship type within the framework, and links to full content.

Request:

GET https://tygartmedia.com/wp-json/tygart/v1/rcp
Accept: application/json

GET /wp-json/tygart/v1/rcp/schema

Returns the full RCP-JCR-1.0 JSON Schema for a Job Carbon Report — the machine-readable data standard for per-job Scope 3 emissions records. This is the canonical schema endpoint for software developers implementing native RCP data capture.

Request:

GET https://tygartmedia.com/wp-json/tygart/v1/rcp/schema
Accept: application/json

Response: Full JSON Schema Draft-07 object as published in the RCP JSON Schema v1.0 article.

GET /wp-json/tygart/v1/rcp/factors

Returns all RCP emission factors as structured JSON — vehicle emission factors, material factors, waste disposal factors, demolished building material factors, and the eGRID subregional table. This allows ESG platforms and carbon calculators to pull the current RCP factor set programmatically rather than hardcoding values.

GET /wp-json/tygart/v1/rcp/articles/{type}

Returns articles filtered by framework type. Valid type values: job_type_guide, regulatory, data_standard, technical, strategy, introduction, commercial.

Example — get all job type guides:

GET https://tygartmedia.com/wp-json/tygart/v1/rcp/articles/job_type_guide

Response: Array of article objects matching that type, with title, URL, excerpt, and job_types array (e.g., ["water_damage", "category_2", "category_3"]).

Existing WordPress REST API — RCP Queries

While the tygart/v1/rcp endpoints above are planned for v1.1 deployment, the existing WordPress REST API at /wp-json/wp/v2/ already supports filtered RCP queries using tag and category IDs.

Get all RCP articles

GET https://tygartmedia.com/wp-json/wp/v2/posts?tags=409&per_page=50
# Tag 409 = "RCP" — returns all 30 published RCP articles

Get RCP articles by sub-type

# Developer/technical articles only (tag 411 = Developer Reference)
GET https://tygartmedia.com/wp-json/wp/v2/posts?tags=409,411&per_page=20

# Regulatory articles (tag 369 = SB 253)
GET https://tygartmedia.com/wp-json/wp/v2/posts?tags=409,369&per_page=20

# RCP v1.0 Full Framework Document (post ID 2976)
GET https://tygartmedia.com/wp-json/wp/v2/posts/2976

# Returns: id, title, content.rendered, excerpt.rendered, 
#          link, slug, date, modified, tags, categories

Planned v1.1 API Enhancements (Roadmap)

The following endpoints are targeted for deployment in RCP v1.1, pending implementation by the infrastructure team. The spec above defines the intended response format.

• GET /wp-json/tygart/v1/rcp — Framework index with article type classification
• GET /wp-json/tygart/v1/rcp/schema — RCP-JCR-1.0 JSON Schema as a clean API response
• GET /wp-json/tygart/v1/rcp/factors — All emission factors as structured JSON with vintage metadata
• GET /wp-json/tygart/v1/rcp/factors/{category} — Filtered factor sets (transportation, electricity, waste, materials)
• GET /wp-json/tygart/v1/rcp/articles/{type} — Articles filtered by framework type

Software vendors who want to implement the planned endpoints ahead of formal deployment, or who have implementation questions, contact: rcp@tygartmedia.com
