# Look up several OpenSea collections at once

`GET /opensea/collections`

## Request

- Base URL: `https://api.crawlora.net/api/v1`
- URL: `https://api.crawlora.net/api/v1/opensea/collections`
- Auth: API key in header `x-api-key`

Resolves up to 50 collections in a single call from a comma-separated `slugs` list, returning each one's floor price, verification flag, headline stats, and per-marketplace listed-item counts. Use this instead of calling `/opensea/collection/{slug}` in a loop — it costs one upstream request regardless of how many slugs you pass. The `markets` array shows how many items are listed on OpenSea versus other marketplaces for the same collection.

## Query parameters

- `slugs` string, required

## Headers

- `x-api-key` string, required

## Response `200`
