Stop shipping answers you can't stand behind
Answer-first capsule: AI and RAG builders do not need another plausible paragraph. They need a dated public-records answer that names the government source and carries the available limitation and observation metadata. A separate snapshot attestation does not sign individual facts. Fonteum turns the same question an LLM might answer from memory into a source-backed answer across .

From plausible text to a source-cited, re-checkable public-records answer
| Capability | Ungrounded LLM answer | Fonteum |
|---|---|---|
| Same question | Which public records show whether a provider or vendor appears on an exclusion list? | Which public records show whether a provider or vendor appears on an exclusion list? |
| Example answer | A plausible paragraph says the organization is probably clear, cites no source, gives no checked date, and may be stale by the time it is read. | The OIG LEIE snapshot contains aggregate exclusion records. Fonteum answers expose source, snapshot-date, limitation, and evidence fields where the response supplies them; no individual record is named in this aggregate example. |
| Source | May blend training data, web memory, or retrieval snippets without a field-level citation. | Government record first — OIG, SAM.gov, CMS, HRSA, or another registered source family named in the answer. |
| Date | Often no as-of date, or a generic phrase like recently. | Responses expose snapshot and last-checked fields where the route and source supply them; missing dates remain explicit. |
| Signature | No signed evidence package travels with the text. | A separate snapshot attestation can expose a digest and signature for its identified object; it does not sign the answer's individual facts. |
| Time-machine edge | Answers the present-tense question only, and may not know what changed since training or retrieval. | As-of reads only for retained rows from named sources. Production history is concentrated in UK sanctions, with small procurement, OFAC, UN, and provenance sets; it is not universal replay. |
| Re-check line | A user can rerun the prompt, but cannot re-create the exact upstream record behind the sentence. | Re-fetch the government file, compare the digest, and re-check the evidence at /verify. |
| RAG handoff | The answer is a text blob the application has to defend after the fact. | The answer ships with source, date, limitation, and evidence pointers that a RAG app can show to the user. |
| Failure mode | Confident, unsourced, and possibly stale output that sounds useful until someone asks for the record. | A dated public-record answer that can be quoted, audited, and re-checked without naming nonessential individuals. |
This comparison is aggregate and FCRA-safe. The worked example cites an OIG LEIE aggregate count and names no individuals; it compares answer mechanics, not any provider, contractor, or person.
The evidence path is the product
Answer-first capsule
Stop shipping answers you can't stand behind. If an AI product answers a compliance, credentialing, diligence, or sourcing question, the answer needs a source, an as-of date, a limitation, and an evidence trail at the moment it leaves the model.
The time-machine edge
Most LLM answers collapse time into now. Fonteum can answer an as-of question only when the named source has a retained row version. Production history is source-specific and sparse outside UK sanctions; current records cannot be treated as universal replay.
The re-check line
A Fonteum answer can expose source and observation metadata. When a concrete snapshot attestation is supplied, its digest can be inspected at /verify; that object-level check does not sign each fact in the answer.

Common questions
- Why is an ungrounded LLM answer a problem for public-records data?
- The problem is not fluency; it is accountability. A public-records answer can affect compliance, credentialing, diligence, or user safety. If the answer has no source, checked date, limitation, or evidence trail, the builder cannot show what record supports it when a user, auditor, or customer asks.
- What does Fonteum add to a RAG or agent stack?
- Fonteum adds the evidence layer: with source, date, limitation, digest, or attestation fields where the response supplies them. A RAG or agent application can cite the government record instead of asking the model to defend an unsupported answer.
- What is the worked example on this page?
- The example is aggregate and FCRA-safe: the OIG LEIE snapshot carries exclusion records. The point is not to name an individual; it is to show the difference between an unsourced answer and a dated answer that points back to OIG as the government record.
- How does the time-machine edge help AI builders?
- Only retained row versions can support an as-of answer. Production history is concentrated in UK sanctions, with small retained sets for procurement, OFAC, UN, and provenance; other sources may have no past row to replay.
- Can I use this through an API?
- Yes. Fonteum exposes public-records data through API surfaces for builders, plus research downloads for aggregate work. Source and evidence metadata varies by route and can be null, so applications must preserve only the fields actually returned.
