  Live fetches of the SEC EDGAR endpoints that serve Antero Resources'
  disclosures, plus the SEC's own published access policy (2026-09-02).
description: >-
  Antero Resources Corporation (NYSE: AR, CIK 0001433270) publishes no API of
  its own, so there is no first-party contract to assert web-API standards
  against. What it does conform to is the disclosure standard its market
  actually runs on: every periodic report it files with the SEC is tagged in
  Inline XBRL against the US GAAP and DEI taxonomies, and the SEC republishes
  those tagged facts as machine-readable JSON. That is the only
  domain-standard conformance evidenced here, and the evidence is a fetched
  200 rather than a marketing claim.
notes: >-
  IMPORTANT PROVENANCE NOTE - the endpoints cited below are operated by the
  U.S. Securities and Exchange Commission, not by Antero Resources. What
  belongs to Antero is the FILING (the Inline XBRL instance documents and the
  taxonomy tagging inside them); the transport, the JSON projection and the
  access policy belong to the SEC. Nothing here should be read as Antero
  publishing an API.
conformance:
  - id: xbrl
    name: XBRL / Inline XBRL (US GAAP + DEI taxonomies)
    conforms: true
    domain_standard: true
    sector: financial-disclosure
    evidence:
      url: https://data.sec.gov/api/xbrl/companyfacts/CIK0001433270.json
      status: 200
      observed: >-
        entityName "ANTERO RESOURCES CORPORATION"; fact taxonomies present in
        the document are dei, srt, us-gaap and ecd, with 454 distinct us-gaap
        concepts tagged across the filing history.
      note: >-
        SEC-mandated for a large accelerated filer; Antero's own filings carry
        the tagging, which is what makes the company's financials machine
        readable at all.
