# Renew a watchlist

Two details decide whether this call succeeds. First, the cibles parameter must repeat the watched targets exactly, because that is what the quote is computed from. Second, the renewal window closes 7 days after expiry: beyond that, the watch is purged and must be recreated.

## What the route returns

Catalogue description, exactly as agents read it:

**Watchlist renewal: extend an existing company monitoring watchlist by 30, 90 or 365 days (?duree=, default 30, any duration whatever the original) of daily surveillance against official sources — $0.05 / $0.135 / $0.50 per target. The cibles parameter must repeat the exact watched targets: it is what the quote is computed from. Possible until 7 days after expiry, then the watch is purged. No refund, no pro rata.**

## Expected identifier

The token returned when the watch was created, in the path.

> ⚠️ A wrongly formatted identifier returns `400` and is **not billed** — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

## Price and billing

Price: **$0.05 (30 j) · $0.135 (90 j) · $0.50 (365 j) / entité**. The authoritative amount is the one in the `402` quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

**Batch** billing: the `cibles` parameter accepts 1 to 100 comma-separated values, and the amount is the unit price times the number of values. The quote is frozen before settlement: there is no partial settlement.

The unit price additionally depends on the `duree` parameter, from a closed list: $0.05 (30 j), $0.135 (90 j), $0.50 (365 j). Default value: 30.

An error response **cancels the payment**: a `400`, `404` or `503` is never billed. An upstream outage closes the route with a `503` rather than serving a degraded response.

## How you pay

Every route is paid **per call**, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a `402` quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is **in preparation**, and we will not announce a date until it is open. Write to [contact@sirenic.eu](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) and we will let you know when it opens.

Paid responses are **Ed25519-signed**: you can later prove what was served to you, and when. The whole catalogue is free to read in the [OpenAPI document](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**
