Trust infrastructure for autonomous agents.
ReARC Labs builds what agents need before they can be trusted to act on their own.
An arch goes up one stone at a time, on a timber frame, with a gap left at the top.
Agent systems go up the same way. The models, the tools and the data are in place, and none of it can carry weight yet.
The last stone lets the rest carry weight. We build that stone.
What the keystone is made of.
Every stone in an arch comes from a quarry you can name.
How agents reach the open web: pages, search, papers, packages, datasets and code. Whatever comes back keeps its source.
Beta. New accounts start with 1,000 free credits.
The masons drew every curve full size on the floor, and kept the old lines under the new ones.
Memory for agents. Every change is a revision you can inspect, compare with an earlier one and roll back.
Live. A permanent free tier, and version 2.3.9 on PyPI.
Every stone carries the mark of the mason who cut it.
An identity for each agent and a public record of what it did. Anyone can dispute an action, and the record shows how it was settled.
Paused in October 2026. It was a Base Sepolia testnet only.
An arch is finished when people start to cross it.

We build the keystone for autonomous agents: who they are, what they remember and where their facts come from.
