## 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-batch-kyb-af96fc96
```

Example prompt: Run a full KYB check on these French companies — SIRENs 552032534, 542107651, 330592911, 775671464 — and give me the complete identity, officers, and compliance alerts for each one.

## When to prefer this

Use this endpoint when you need KYB data for multiple French companies (2–100) and want to minimize API calls and cost (30% discount vs. unit price). Prefer this over single-company KYB when processing prospecting lists, onboarding batches, or portfolio compliance reviews. If you only need one company, use the single-company KYB endpoint instead.

## Known failure modes

- Fewer than 2 or more than 100 SIRENs submitted — request rejected
- Invalid SIREN format (not 9 digits) — validation error
- SIREN exists but company is non-diffusible — returns trouve=false, still billed
- Network timeout on large batches — retry recommended
- Payment failure via x402 — 402 response, no data returned

## How this service works

Batch KYB and bulk company lookup: full Know Your Business files for 2 to 100 French companies in one call (comma-separated sirens parameter) — bulk due diligence, compliance and onboarding screening of a whole portfolio, each file with per-block provenance (official register + as-of date). Billed per company at $0.105 (30% off the $0.15 unit price); the amount is quoted from the number of SIREN. A SIREN with no diffusible company is returned as trouve=false and billed as one lookup.

## Output

Returns an array of KYB records, one per SIREN submitted. Each record includes full company identity, legal form, officers, BODACC alerts, financial indicators, and a trouve flag (true/false) indicating whether diffusible data exists. Non-diffusible SIRENs return trouve=false and are still billed as one lookup each.
