Fini

Fini AI provides self-improving AI agents for enterprise customer support across voice, chat, and email. Built on a RAGless retrieval engine, the Fini Agent Loop, a self-updating Knowledge Atlas, and Agentic Actions, Fini understands customer intent, retrieves the right data, and takes action — resolving up to 90% of support tickets at 99% accuracy. It is purpose-built for regulated industries such as fintech, banking, healthcare, insurance, and e-commerce, with PII redaction, audit trails, and guardrails. Fini exposes a public v2 REST API for managing agents, conversations, knowledge (sources, articles, folders), rules, tags, and prompts, and for driving the agent loop through its Generate Answer endpoint. Backed by Y Combinator (S22) and Matrix Partners.

Fini publishes 9 APIs on the APIs.io network, including Agents API, Articles API, Conversations API, and 6 more. Tagged areas include Company, Artificial Intelligence, AI Agents, Customer-Support, and Customer Experience.

Fini’s developer surface includes documentation, API reference, engineering blog, pricing, signup flow, authentication, and 20 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/fini: open an issue to ask a question, or submit a pull request to add artifacts.
