## 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 invoket-peppol-participant-lookup-b36ab8cc
```

Example prompt: Before I send an e-invoice to Société Générale, check if they're registered on the Peppol network — their SIREN is 552120222 — and tell me what document types they accept.

## When to prefer this

Use this endpoint when an AI agent needs to verify Peppol e-invoicing eligibility for a French company (via SIREN or SIRET) or any company via explicit Peppol participant ID before dispatching an e-invoice; it requires no account or API key, making it ideal for lightweight, on-demand lookups in automated invoice workflows.

## Known failure modes

- Company not found in Peppol Directory — returns a paid 'not registered' dated response
- Invalid or malformed SIREN/SIRET format — returns a validation error
- Peppol Directory data temporarily unavailable — service error
- Ambiguous identifier requiring explicit Peppol participant ID

## How this service works

Check whether a company can receive e-invoices on the Peppol network before you send one: participant identifiers and accepted document types from the official Peppol Directory export, by SIREN, SIRET or explicit Peppol participant ID. 'Not registered' is a paid, dated answer. No account, no key.

## Output

Returns whether the company is registered on the Peppol network, its participant identifiers, and the list of accepted document types; a 'not registered' response is a paid, dated authoritative answer from the official Peppol Directory export.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "required": [
  "siren"
 ],
 "properties": {
  "siren": {
   "type": "string",
   "description": "9-digit SIREN of the French legal unit. Provide exactly one of 'siren', 'siret' (14 digits, matched on its SIREN prefix) or 'participant' ('<icd>:<value>', explicit Peppol participant ID, any country - e.g. '0009:33328563300033'). Malformed input is a 400 (INVALID_INPUT), a failed Luhn checksum is a 400 (INVALID_CHECKSUM, likely a typo). An identifier absent from the directory is NOT a 404: it is a successful 'reachable: false' answer (200, billed). The only 404 on this route is a well-formed 'siret' that does not exist in the Sirene register (a mistyped establishment number) - not billed, same answer as /company/resolve; 'siren' and 'participant' have no existence check"
