UK company officers

get_uk_company_officers
Read-only

UK company officers and directors, live from Companies House, the official UK company registry: directors and secretaries with role, appointment date, nationality, occupation, country of residence and month+year of birth only — never a correspondence address (GDPR minimisation). Includes active/resigned counts. Open Government Licence v3.0. Paid via x402 ($0.01 in USDC or EURC).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
api_keyNoOptional Sirenic API key (srn_live_…) to pay with prepaid credits instead of x402 — no wallet needed. Get one at https://api.sirenic.eu/compte. Ignored when x_payment is provided (the signed payment wins). On insufficient balance the tool returns a credits error, not an x402 quote.
x_paymentNoOptional signed x402 PAYMENT-SIGNATURE header value. Omit to receive the payment quote.
company_numberYesCompanies House company number, 8 characters incl. leading zeros, e.g. 00102498 or SC123456

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
hintNoHow to settle the quote, present when payment_required is true.
quoteNoThe signable x402 payment requirements when payment_required is true: {x402Version, accepts[]} where each entry carries scheme, network, amount, asset and payTo (USDC and EURC options at the same numeric amount). Sign one entry and call again with `x_payment`.
resultatNoThe endpoint's JSON response when payment_required is false. Paid responses carry `source`, `disclaimer` and an Ed25519 signature; KYB, batch KYB, sanctions, intelligence and the five invoicing tools (prepare_french_invoice_file, prepare_european_invoice_file, prepare_french_einvoicing_recipient, verify_iban_bank, validate_eu_vat_number) also carry a `provenance` array — one entry per block served, with the official register, licence, version, `as_of` date and `precision_as_of` (what that date means). Codes are documented at GET /v1/provenance/registres (free).
payment_requiredYesTrue when this response is an x402 payment quote instead of data: settle one of the quote's `accepts` options and call the tool again with `x_payment`.

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds value beyond this by disclosing GDPR data minimisation ('never a correspondence address'), the licensing (Open Government Licence v3.0), the payment requirement, and that it includes active/resigned counts. No contradiction exists; the description enriches the safe read-only profile with specific data-handling behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single dense sentence that front-loads the core purpose ('UK company officers and directors, live from Companies House') before listing fields, GDPR note, and payment. It is information-rich without redundancy. It packs a lot into one sentence but stays readable and every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has an output schema (per context signals) so return values need no description. The description covers the data source, field list, privacy constraints, licensing, payment method, and counts – sufficient for an agent to invoke it appropriately. Minor omissions like error handling or rate limits are not critical for a read-only tool with annotation coverage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with detailed descriptions for all three parameters, including the interplay between api_key and x_payment ('Ignored when x_payment is provided'). The description does not add parameter-specific meaning beyond the schema; it only restates the payment mechanism at a high level. Baseline 3 is appropriate given the schema's thoroughness.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb ('get'), resource ('UK company officers and directors'), and source ('live from Companies House, the official UK company registry'). It enumerates the exact data fields (role, appointment date, nationality, occupation, country of residence, birth month/year) and distinguishes from UK-related siblings like get_uk_company_accounts by focusing on officers. The GDPR minimisation note further clarifies scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context that this tool is for UK-specific company officer data, and implicitly indicates it should be used when officer/director information is needed. It does not explicitly name alternative tools or when-not-to-use, but the UK scoping is unambiguous. The mention of payment method (x402) adds usage context, though no exclusions or alternatives are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.6/5.0
Disambiguation2/5

Several French company bundles overlap in purpose (get_french_company_file, get_french_company_kyb_file, get_french_company_intelligence, get_french_company_health_summary) and procurement/competitor tools overlap (get_french_company_public_procurement, get_eu_procurement_awards, get_company_procurement_competitors). Although descriptions try to differentiate, an agent could easily select the wrong tool when looking for a company overview or procurement history.

Naming Consistency4/5

Most tools follow a consistent get_/list_/search_ + country + entity pattern, e.g. get_french_company_profile, list_danish_company_filings, so navigation is predictable. Deviations like check_french_regulator_alerts, suggest_company_names, verify_iban_bank, and the prepare_* verbs are understandable but break the strict verb_noun pattern.

Tool Count1/5

77 tools is excessive for a single server regardless of how broad the domain is; the calibration treats 50+ as an extreme mismatch. While France is well covered and several countries appear, much of the surface is micro-endpoints (list_/get_ filing pairs per country) that could be consolidated.

Completeness3/5

France coverage is impressively complete (identity, financials, legal events, procurement, IP, risk, surveillance, invoicing), and the surveillance lifecycle has create/get/renew/stop. But European coverage is inconsistent: Germany has only insider transactions, Spain only acts, and several major jurisdictions lack accounts/officers/insolvency; an agent expecting 'European company due diligence' will hit dead ends.
