This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Built Robotics is a San Francisco robotics company, founded in 2016 by Noah Ready-Campbell and Andrew Liang, that turns conventional heavy construction equipment into AI-powered autonomous robots. Its Exosystem retrofit kit converts excavators and other earthmoving machines into self-operating robots for trenching, foundation excavation and pad grading, while the RPD 35 and RPS 25 autonomous pile drivers install foundations for utility-scale solar farms. Machines are supervised from the Everest command center, and field deployment is run through its Built Solar Technologies (built.solar) division.

Built Robotics publishes no public API. Contract discovery (2026-08-01) probed
www.builtrobotics.com, built.solar and everest.builtrobotics.com for OpenAPI/Swagger,
GraphQL introspection, MCP tools/list and A2A agent cards at both well-known paths — all
missed. The company's own llms.txt / llms-full.txt site inventories contain no developer
or API section, and no public repo in its GitHub organization carries a spec or .proto.
What it does publish, and what this repo captures:
| Artifact | What was found |
|---|---|
llms/ |
A real, provider-published llms.txt (186 lines), saved verbatim |
well-known/ |
A real RFC 9116 security.txt (expiring), plus robots.txt with an explicit AI-agent vs AI-training policy |
security/ |
Vulnerability-disclosure contact + policy, and a TLS/DNS domain-security probe |
packages/ |
One first-party open-source package — rsplan on PyPI (a Reeds-Shepp path planner). Not an API SDK |
conformance/ |
Which web/agent discovery standards the company adopts, with evidence |
