Tapis v3 Research Computing Platform (TACC production tenant)

Tapis is the API platform TACC builds and operates for programmatic access to research computing: registering storage and compute systems, moving files, defining applications, submitting and tracking HPC jobs, and subscribing to job events. The production TACC tenant serves five OpenAPI 3.0.3-described services, all verified healthy (HTTP 200 on /healthcheck) on 2026-08-30. Reads and writes require a tenant-issued JWT; the health-check endpoints are anonymous. This is the one surface in this profile where the institution wrote the contract.

Documentation Provider Profile APIs.io OpenAPI GitHub

Where this information came from

This is an independent, third-party profile of Tapis v3 Research Computing Platform (TACC production tenant), published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
