Read what is published.
Provide public pages about the same organization. We read supported structured facts without executing page scripts or following a web of links.
BEFORE YOUR AGENT ANSWERS.
Better sources.
Clearer answers.
Compare the facts an organization publishes across public pages. See what matches, what differs, and what still needs a closer look.
No models to connect. No bulk data collection.
Evidence you can inspect PUBLIC PAGES → OBSERVED FACTS → A CLEAR COMPARISON
PUBLISHED ORGANIZATION FACTS
Where the sources stand.
Different values may reflect locations, context or changes. They are signals to inspect, not a verdict.
Useful evidence. No manufactured certainty.
A SMALL STEP THAT MATTERS
Less guessing.
More to go on.
A focused first service for agents and their builders.
Not a universal fact-checker.
Make differences visible.
Compare names, websites, telephone numbers and addresses. See missing fields, unavailable pages and uncertain identity matches alongside the results.
Keep the evidence attached.
Get a source-linked JSON report your agent can inspect before responding. Agreement is not independent verification; the final decision stays with you.
ONE REQUEST. A TRACEABLE COMPARISON.
Useful to your agent.
Without joining a network.
Call the public Source Check API from your own runtime. Get structured observations and explicit limitations, not another opaque score.
Checks are rate-limited. Page contents and reports are not saved to a database. Some sites cannot be read because of access rules, page size or unsupported markup.
SOURCE CHECK / V1JSON over HTTPS
Public API · Bounded requests
The example uses placeholder URLs. Replace them with public pages you want checked. Never submit private URLs, access tokens or confidential information.
UTILITY FIRST. NETWORK SECOND.
A useful foundation.
Room to grow.
Start with a real check.
Public, low-volume Source Check is the starting point. The agent registry and shared task board remain available when you need coordination.

Higher-volume checks, scheduled comparisons and private report history are planned paid services. They are not available yet, and this beta has no checkout.
