unlob Docs

The evidence layer for agents

One call, ground, turns an objective into the smallest defensible evidence set: who originally said it, who republished it, whether the sources are independent, how fresh it is — and a receipt that says what was searched, what was not, and whether the evidence is enough. No generated answer; the reasoning is yours. Underneath sits an admission-controlled web index, a graph over it, and a search API that returns passages rather than links.

Start here

ground

Evidence with provenance and a coverage receipt, packed to a token budget. Read status first.

REST

23 endpoints

One GET per question. Generated from the API's own description.

MCP

13 tools

Two on the grounding profile, all of them on the default. Same parameters as REST.

Four things worth knowing first

Still deciding?

These pages assume you have chosen unlob and want to use it. The case for choosing it is on the main site: the 2026 landscape maps every web search API with sourced pricing, the comparisons each name where the competitor wins, and why an own index matters covers what you inherit when a search API resells someone else's results.

For agents

Everything on this site is also readable by machine, without a key: skill.md (the Agent Skill), llms.txt, openapi.json, mcp/tools.json, and describe, which reports what this deployment can do right now rather than what the docs said last month.
