Chai Research

Chai Research Corp. (CHAI) is a Palo Alto consumer AI company building a character-and-story chat platform, where users create and talk to AI characters on iOS, Android and the web. Founded in 2021 by William Beauchamp, the company trains and serves its own conversational language models on an in-house GPU cluster, and runs Chaiverse — a developer platform where outside model builders submit HuggingFace-hosted language models, have them deployed to real Chai App users, and compete on a public leaderboard. A public Chat API (api.chai-research.com) and a chaiverse pip package were previously documented; both have since been withdrawn — see x-coverage.

human only

More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.

Kin Score

API Evangelist profiles Chai Research 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 — Chai Research scores 17.0/100 (emerging), 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.

Behind a wall

Why this profile is thin

The Chat API documentation host docs.chai-research.com no longer resolves in DNS and the documented POST /v1/chat/completions route now returns a bodyless 404, leaving the Chaiverse developer console as the only live developer surface — and every path on console.chaiverse.com, including /openapi.json, answers HTTP 307 to /login, with the developer key issued only through the Chaiverse Discord bot or a HuggingFace OAuth sign-in.

An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is Chai Research's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

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 Chai Research

Each block below is one kind of artifact we hold for Chai Research. 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.

Where this information came from

This is an independent, third-party profile of Chai Research, 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.
