An API platform that adds persistent, per-user memory to AI agents, along with connected accounts, action limits and audit trails.
What it is
Harny is an agent harness infrastructure platform built by Vexta Labs Inc. It provides AI agents with per-user memory that updates as facts change, connected user accounts, enforced action limits, and a complete audit record of all agent actions. The platform offers a simple API with four endpoints for ingesting timestamped data, checking ingestion status, recalling ranked memory with dated evidence, and deleting data. Harny's memory system scores 85.1 on the BEAM benchmark at 128K tokens, the highest published result at that size. Every user's data is strictly scoped to that user, with no sharing across users. The system uses 98% fewer tokens than raw tool output, making agent responses 4× cheaper to generate.
Systems
- Timestamped memory ingestion with backdating capability
- Per-user data isolation and privacy scoping
- Ranked memory recall with dated evidence
- Connected accounts integration per user
- Long-running agent jobs with folder-level operations
- Configurable token ceiling per API call
- Enforced action limits on agent operations
- Complete action audit trail with hash chaining

Quick answers
- What do I send to Harny?
- Text plus a timestamp: emails, meeting transcripts, chat messages, support threads, CRM notes, documents. There is no schema to define, no embedding model to choose and no chunking pipeline to build.
- What comes back from a recall?
- Recall returns ranked memory for your model. The response carries asOf, usedEvidenceTokens and results. Each result is one memory with its content, its artifact and the dated data points behind it.
- How is Harny different from search or RAG?
- Search and RAG return text that looks like the question. Harny returns what is true now, what it replaced and where each value came from. Ask about the Acme budget and you get 40k, with the date it changed and the email that changed it.
- How much does Harny cost?
- The first 500 monthly-active end users in your active app are free for good. You pay only for users above 500, at $0.30 per monthly-active end user per month, and a user counts in a month when they used your app that month.
- Does Harny use my data to train AI models?
- No. Harny does not use your data to train general AI models.
