# Lloyd's syndicate dossier (capacity + result forecast + US eligibility)

`GET /v1/syndicates`

## Request

- Base URL: `https://api.querylines.com`
- URL: `https://api.querylines.com/v1/syndicates`
- Auth: none declared

Lookup mode (`syndicate` given): one syndicate's capacity and Lloyd's estimated result forecast per year of account, plus its US-eligibility cross-reference (joined by syndicate number to this API's insurer eligibility data). Browse mode (omitted): the active-syndicate roster, optionally filtered by `managing_agent`. Estimated results are Lloyd's own forecast RANGES on a year-of-account basis, not audited results. $0.10 per query.

## Query parameters

- `syndicate` string
- `managing_agent` string
- `limit` integer

## Response `200`

## Other responses

- `400`: Invalid query parameters.
- `402`: Payment required (x402). Returned when the x402 payment gate is enabled (PAY_TO_ADDRESS configured) and the request carries no valid payment. The full payment challenge (price/network/payTo/asset) is carried in the base64-encoded PAYMENT-REQUIRED response header (see the x402 spec), not the JSON body -- the body is `{}` for API clients. Price for this route: $0.10. Retry with a signed payment per x402 (USDC on Base mainnet); on success the response carries a PAYMENT-RESPONSE header with settlement info. When PAY_TO_ADDRESS is unset (kill switch off), this route is free and never returns 402.
- `404`: Unknown state or coverage line.
- `500`: Internal error.
