## 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 esma-mica-token-registry-lookup-d22372cb -d '<json body>'
```

Example prompt: Can you check if Circle Internet Financial is registered under MiCA in the EU? I want to verify whether their EURC token is on the ESMA interim register — search by issuer name.

## When to prefer this

Use this endpoint when you need to verify whether a specific crypto-asset issuer or token is officially notified under EU MiCA regulation before trusting it in a financial workflow, accepting stablecoin payments, or performing compliance due diligence. Prefer this over generic web search when you need structured, authoritative regulatory data from the official ESMA interim register.

## Known failure modes

- No match found for the given issuer name, LEI, or DTI — returns empty results
- Issuer exists but is registered under a slightly different legal name — partial or no match
- ESMA register data may lag behind real-time regulatory updates
- Malformed or invalid LEI/DTI format causes lookup failure
- Network timeout to the upstream ESMA data source

## How this service works

Is this crypto-asset or its issuer MiCA-notified in the EU? Searches the official ESMA interim MiCA register token lists — e-money token (EMT) issuers, asset-referenced token (ART) issuers, and notified crypto-asset white papers — by issuer name, LEI, or Digital Token Identifier (DTI). Returns issuer, home member state, competent authority, DTIs and the official white-paper URL per match. Useful before trusting a stablecoin or token sold as EU-regulated.

## Output

Returns a list of matching entries from the ESMA MiCA interim register, each with issuer name, home EU member state, competent authority, associated Digital Token Identifiers (DTIs), token type (EMT or ART), and the official white paper URL if available. Returns empty results if no match is found.
