Alliance Holdings

Alliance Holdings GP, L.P. (AHGP) was a limited partnership formed to own and control Alliance Resource Management GP, LLC, the managing general partner of Alliance Resource Partners, L.P. (ARLP), the second largest coal producer in the eastern United States. AHGP held a general partner interest, incentive distribution rights, and a direct stake in ARLP common units. In 2018 AHGP was absorbed into ARLP in a simplification transaction and ceased to exist as a separate public entity. ARLP (NASDAQ: ARLP) continues as a diversified energy company earning income from coal production and from coal, oil and gas mineral royalties. Alliance Holdings never maintained a public developer API program and neither does the surviving entity. The legacy ahgp.com host no longer resolves and alliancecoal.com redirects to www.arlp.com; probes on 2026-09-04 of arlp.com, www.arlp.com and investor.arlp.com found no OpenAPI, GraphQL, AsyncAPI, gRPC, WSDL, MCP, agent card, or served /.well-known/ document.

Alliance Holdings is profiled on the APIs.io network. Tagged areas include Energy, Coal, Mining, Natural Resources, and Financial-Services.

scored 2026-09-10 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/alliance-holdings: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Alliance Holdings GP, L.P. was absorbed into Alliance Resource Partners in the 2018 simplification transaction and
    its own host ahgp.com no longer resolves (NXDOMAIN on the apex, certificate-name mismatch on www), so the only surface
    left to probe is the successor's twelve-page WordPress corporate site at www.arlp.com — which has no developer section,
    returns 404 for /openapi.json, /swagger.json, /api-docs, /graphql, /llms.txt and every /.well-known/ path, and whose full
    Yoast page sitemap lists no documentation, reference or portal page at all.
