## 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 tanod-peppol-participant-lookup-35276082 -d '<json body>'
```

Example prompt: Check if Norwegian organisation number 983887457 is registered on the Peppol network and tell me which document types they can receive.

## When to prefer this

Use this endpoint when you need to verify whether a specific trading partner is reachable on the Peppol e-invoicing network before sending or routing an electronic invoice. Prefer this over manual DNS lookups or Peppol directory web UIs when operating in an automated agent workflow. It is the right choice when you need both registration status and supported document types in a single call, particularly for European B2B e-invoicing workflows using standard ICD codes like 0192 (Norway), 0184 (Denmark), or 0106 (Netherlands).

## Known failure modes

- Invalid or malformed participant ID format returns validation error
- Participant not found on Peppol DNS returns registered=false with no document types
- SMP unreachable or returns an error populates smp_error field with details
- Unsupported identifier scheme (anything other than iso6523-actorid-upis) returns error
- Network timeout reaching Peppol SML/SMP infrastructure

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object indicating whether the participant is registered on Peppol (boolean), the SMP URL for their access point, the SML DNS hostname used for discovery, any SMP resolution error, a timestamp of the check, and an array of supported document type identifiers with human-readable labels. Also includes a caveat note that DNS registration does not verify legal status.
