## 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-eu-financial-authorisations-esma-mifid-registry-558170a0
```

Example prompt: Can you check whether Amundi Asset Management is authorised under MiFID in the EU — I need its authorisation status, home member state, and which competent authority oversees it?

## When to prefer this

Choose this endpoint when you need to verify the MiFID regulatory status of EU/EEA investment firms, UCITS managers, or AIFMs across all 27+ member states in a single call. It is the right choice for KYB/KYC compliance workflows, counterparty due diligence, onboarding screens, or any use case requiring official ESMA authorisation data. Prefer it over manual ESMA register lookups or country-by-country national regulator queries — one integration covers the entire EU/EEA.

## Known failure modes

- Entity not found — SIREN not matched in ESMA register, returns empty result or 404
- Invalid SIREN format — non-9-digit input causes validation error
- Entity exists but is not MiFID-regulated — no result returned
- ESMA source data temporarily unavailable — upstream data refresh lag
- Ambiguous name match — multiple entities returned requiring disambiguation

## How this service works

EU financial authorisation lookup in the official ESMA Registers: search ~14,000 MiFID-regulated entities across the EU/EEA (investment firms, UCITS/AIFM managers) by name or LEI — authorisation status of the regulated entity, home and host member states, competent authority, authorisation dates. One integration covers all 27+ countries of Europe: an investment firm and regulated entity KYB check for the whole single market. Data freely available at the source (ESMA).

## Output

Returns structured data on the matched MiFID-regulated entity including: full legal name, authorisation status (authorised/withdrawn/refused), home member state, host member states where passported, competent authority name, and authorisation/withdrawal dates — sourced from ESMA's official registers covering all 27+ EU/EEA jurisdictions
