Live Freshness Validator
Policies, prices and API documentation change, but your agent doesn't notice. Freshness Validator monitors the sources your agents rely on and tells them, in a single call, whether their information is still correct.
| Context the agent holds | Score |
|---|---|
| Rate limit is 100 requests per minute Source unchanged since last check |
92 fresh |
| Support hours end at 5 pm Validated 6 days ago, policy is 7 days |
74 warning |
| Refund window is 30 days Source page changed after last validation |
58 stale |
Customers, colleagues and other systems get today's facts, not the version your agent loaded last month.
Instead of loading entire documents into every request just in case, the agent re-reads a source only when it has actually changed.
No searching for incorrect answers after a policy change, and no debugging code written from outdated documentation.
Enter your own numbers. The math runs in your browser.
Register a source, then check information against it. Replace the example key with your own.

}Full API reference and MCP setup
It scores how fresh an AI agent's context is, from 0 to 100, by combining how long ago it was validated, whether its source page has changed, and how closely the text still matches the source. Scores below 70 are flagged as stale.
No. Submitted context is scored in memory and not stored. Only the text of the source pages you register is kept, to detect changes.
Yes. The same validation engine is available over REST at api.myuiaf.com and as an MCP server at https://api.myuiaf.com/mcp.
From $0.03 per validation call on the Early Testing tier down to $0.015 on Enterprise. Registering a source costs two calls. An agent with no account can pay $0.05 in USDC for a single call.
The call returns HTTP 402 with no charge and no result, and tells the agent how to buy more credits or pay for the single call.
The same API key and prepaid credits also work with AgentPay, our pay-per-call gateway to third-party APIs. One wallet covers both services.
