Tool changes

2026-09-29analyze_companychangedtitle, description, input schema, annotationsmeaning changed
before
Legacy experimental company analysis. Financial and credit figures are placeholders, not verified risk assessments.
after · 15% of words in common
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.
2026-09-29assess_importchangedtitle, description, annotationsmeaning changed
before
Legacy EU import assessment response with classification, duty, VAT, compliance, landed cost, and missing inputs. Use factrail_assess for an EvidenceEnvelope. Results are indicative and are not binding customs rulings.
after · 25% of words in common
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.
2026-09-29verify_french_companychangedtitle, description, annotationsmeaning changed
before
Verify a French company by SIREN (9-digit) or SIRET (14-digit). Returns structured verified data from INSEE Sirene (official company register) with BODACC company-event intelligence (legal notices, proceedings, filings). Legacy response shape; use factrail_verify for an EvidenceEnvelope.
after · 22% of words in common
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.
2026-09-29factrail_get_receiptchangedtitle, description, output schema, annotationsmeaning changed
before
Retrieve the immutable EvidenceEnvelope associated with a FACTRAIL receipt ID.
after · 16% of words in common
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.
2026-09-29factrail_verifychangedtitle, description, output schema, annotationsmeaning changed
before
Establish evidence-backed facts about a supported subject. Supports French companies by SIREN or SIRET; returns facts, provenance, coverage, and a receipt.
after · 42% of words in common
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.
2026-09-29factrail_assesschangedtitle, description, input schema, output schema, annotationsmeaning changed
before
Perform an evidence-backed structured assessment. Supports import scenarios and returns an EvidenceEnvelope with source coverage and a receipt.
after · 30% of words in common
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.
2026-09-29factrail_capabilitiesadded
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.
2026-09-27analyze_companyadded
Legacy experimental company analysis. Financial and credit figures are placeholders, not verified risk assessments.
2026-09-27assess_importchangeddescriptionmeaning changed
before
Assess an import into the EU from any origin country. France is the best-supported destination in V0. Returns structured classification, customs duty, import VAT, compliance requirements, landed cost, missing-information questions, risk profile, and source-backed evidence. This is a pre-purchase / pre-import decision tool — it does NOT file customs declarations, book freight, or track shipments. Returned classifications are NOT legally binding and must be reviewed before use in customs filings. Where information is missing or a source is unavailable, the tool returns explicit questions and unavailable markers rather than fabricated data.
after · 21% of words in common
Legacy EU import assessment response with classification, duty, VAT, compliance, landed cost, and missing inputs. Use factrail_assess for an EvidenceEnvelope. Results are indicative and are not binding customs rulings.
2026-09-27verify_french_companychangeddescription
before
Verify a French company by SIREN (9-digit) or SIRET (14-digit). Returns structured verified data from INSEE Sirene (official company register) with BODACC company-event intelligence (legal notices, proceedings, filings). Read-only — does not modify any state. Accesses open-world data sources including the French government's official APIs.
