# Top 24h crypto losers (universe scan)

`GET /api/coins/top-losers`

## Request

- Base URL: `https://api.coinrithm.com`
- URL: `https://api.coinrithm.com/api/coins/top-losers`
- Auth: none required

Keyless scan of CoinRithm's tracked coin universe for the largest 24h
price DECREASES, ordered by 24h change percent ascending. Identical
shape and identical caveats to `/api/coins/top-gainers`: bare array,
`ucid` is the `coinId`, numerics are decimal strings, default limit 3,
out-of-range limits 400 rather than clamp.

## Query parameters

- `limit` integer

## Response `200`

Top losers, ordered by 24h change ascending

- PublicCryptoMover[]: Bare array — this endpoint has no envelope, no pagination block.
  - `ucid` string, required: CoinRithm coin id. This is the SAME identifier the agent endpoints call `coinId`; pass it straight through rather than resolving the symbol (symbols collide across listings).
  - `symbol` string, required
  - `name` string, required
  - `slug` string, required: Public site slug (https://www.coinrithm.com/en/cryptocurrencies/{slug}).
  - `change24h` string, required: 24h price change in PERCENT, as a decimal string. Negative on the losers feed.
  - `currentPrice` string, required: Latest USD price as a decimal string.
  - `priceUpdatedAt` string, date-time, nullable: When the live price was last written; null when unknown.
  - `priceAgeHours` number, nullable: Hours since the live price was last written, one decimal; null when unknown.
  - `priceStale` boolean: True when the last live write is older than `priceStaleAfterHours`. The price stays in the row; treat it as a last known price.
  - `priceStaleAfterHours` number: Staleness threshold in hours (currently 72).

## Other responses

- `400`: Invalid or missing parameters. On a route with a query allowlist, an undocumented query parameter returns `{"error": "unsupported_query_parameter", "message": "Unsupported query parameter: <key>. Supported: <keys>."}`.
- `500`: Server error
