Antora Energy
Antora Energy is a San Jose, California clean-energy hardware company founded by Justin Briggs, Andrew Ponec and David Bierman that designs, manufactures and deploys factory-built thermal batteries for heavy industry, data centers and the grid. Antora's system resistively heats blocks of solid carbon to temperatures up to 2,400C when electricity is cheapest, stores that energy for multiple days in a compact modular unit, and discharges it around the clock as radiant heat delivered directly to industrial processes or paired with off-the-shelf steam turbine equipment for firm power; the company also develops thermophotovoltaic (TPV) heat-to-power cells at what it describes as the world's largest TPV manufacturing line. Its HeatCore product delivers heat up to 375C at 300 kW-thermal per module, and its power block is rated at 50 MW-electric. Antora's first giga-scale deployment, Project Big Stone, is a 5 GWh system of more than 200 thermal batteries at POET's bioprocessing plant in Big Stone City, South Dakota, built from empty lot to energy delivery in under twelve months. The company closed a $550 million Series C in 2026. Antora sells energy hardware and long-term energy offtake rather than software: it publishes no developer program, no public API, no SDK and no machine-readable API contract, and its only public software surface is Insight, an authenticated steam and power optimization dashboard for named project stakeholders.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Antora Energy the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Antora Energy scores 11.7/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Antora Energy manufactures thermal battery hardware and sells industrial heat and power under long-term offtake agreements, so there is no product to expose as an API; its only software surface is Insight, an authenticated dashboard at app.antora.com built for POET and Antora project stakeholders, whose client bundle contains no first-party API host, and api./developers./docs./portal.antora.com do not resolve in DNS at all.
This is an honest zero, not a gap in our research. Antora Energy does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Antora Energy
Each block below is one kind of artifact we hold for Antora Energy. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Antora Energy, 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.
