Tools
| Tool | Description | Behaviour |
|---|---|---|
| analyze_company | Deprecated: use factrail_verify instead. Use only when an older integration still calls this experimental tool; financial and credit data sources are unavailable and returned fields are null. | Read-only |
| assess_import | Deprecated: use factrail_assess instead. Use when an older integration still expects the legacy beta EU import assessment format; coverage may be partial or provisional and this is not a binding customs result. | Read-only |
| factrail_assess | Use when you need a source-backed assessment of importing a product into the EU (tariff classification, duties, and related evidence). Returns an EvidenceEnvelope; import assessment is Beta and results expose source coverage and support levels. | Read-only |
| factrail_capabilities | Use when you need to discover what FACTRAIL can verify or assess before calling another tool. Returns available capabilities, inputs, fields, sources, versions, and limitations; call first to inspect current coverage and source state. | Read-only |
| factrail_get_receipt | Use when you need to re-fetch or audit a previously returned FACTRAIL result by its receipt ID. Recomputes the stored EvidenceEnvelope's content hash and rejects altered content; this checks integrity, not truth. | Read-only |
| factrail_verify | Use when you need verified, source-backed facts about a French company from its SIREN or SIRET. Returns Evidence with provenance, freshness, coverage, conflicts, and a reusable receipt. | Read-only |
| verify_french_company | Deprecated: use factrail_verify instead. Use when an older integration still expects the legacy flat French company lookup by SIREN/SIRET; kept callable for compatibility only. | Read-only |
