## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-uk-company-accounts-filings-list-834a4d20
```

Example prompt: Can you list all the accounts filings Sirenic has decoded for UK company number 00095407, including the accounting periods, frameworks like FRS 102 or micro-entity, and currency?

## When to prefer this

Use this endpoint when you need structured metadata about all historical accounts filings for a UK-registered company, particularly to check accounting frameworks, filing periods, and balance-sheet dates sourced from the official Companies House data product. Prefer this over scraping Companies House directly when you need decoded, structured output. Note it only covers electronically filed accounts, so supplement with direct Companies House queries if completeness is critical.

## Known failure modes

- Invalid or non-existent company number returns empty list or 404
- Company has only paper-filed accounts — returns empty decoded list even if accounts exist at Companies House
- Missing leading zeros in company number causes no match (must be exactly 8 characters)
- Unsupported prefix formats return no results
- Rate limiting or payment failure (x402) if USDC payment not processed

## How this service works

UK annual accounts filings list — financial statements from iXBRL in the official Companies House Accounts Data Product (Open Government Licence v3.0). Query: /v1/eu/entreprise/GB/00095407/comptes (8-character company number, leading zeros included, SC/NI/OC prefixes supported). Every decoded balance sheet date with period, entity name, currency, accounting framework (micro-entity, FRS 102...) and accounts type. Electronically filed accounts only — absence does not mean no accounts exist.

## Output

A list of all electronically filed accounts that Sirenic has decoded for the given UK Companies House company, with each entry including the balance-sheet date, accounting period, entity name, currency, accounting framework (e.g. micro-entity, FRS 102, FRS 105), and accounts type. Note: absence of entries means no electronically filed accounts were decoded, not necessarily that no accounts exist.
