Mercari API endpoint
Use Crawlora's Mercari search API to extract supported public Mercari data as structured JSON. This page includes request parameters, cURL examples, response schema, error behavior, credit cost, and a Playground link for testing before integration.
/mercari/searchSearches Mercari's live resale marketplace by free-text keyword, returning normalized listing summaries (title, price, thumbnail, condition, seller) plus the total matching count. Credential-free public data sourced from Mercari's own mobile-app API using an anonymous, login-free session. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and agent-native workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.
Request parameters are generated from the active endpoint catalog. Required values must be sent before Crawlora can call the upstream public web data source.
| Parameter | Type | Required | Default | Description | Example |
|---|---|---|---|---|---|
| query | string | Yes | Free-text keyword search | ||
| x-api-key (header) | string | Yes | API key required |
curl -X GET "https://api.crawlora.net/api/v1/mercari/search?query=coffee" \ -H "x-api-key: $CRAWLORA_API_KEY"
Send your scraping API key in the x-api-key header. Use the console API Keys page to rotate or select the active key.
Endpoint usage is metered in credits. The plan prices, included credits, limits, and overage rates below match the active backend billing configuration.
| Plan | Price | Included credits | Daily cap | Rate limit | Overage |
|---|---|---|---|---|---|
| Free | $0/mo | 2,000 | 500 daily credits | 5/min | No overage |
| Starter | $9/mo | 20,000 | 5,000 daily credits | 15/min | $0.75/1,000 overage credits when enabled |
| Growth | $29/mo | 100,000 | 25,000 daily credits | 45/min | $0.45/1,000 overage credits when enabled |
| Pro | $79/mo | 400,000 | No daily cap | 120/min | $0.30/1,000 overage credits |
| Business | $199/mo | 1,200,000 | No daily cap | 300/min | $0.20/1,000 overage credits |
| Enterprise | $499/mo | 5,000,000 | No daily cap | 1,000/min | $0.12/1,000 overage credits |
This endpoint is executed through Crawlora's managed scraping infrastructure.
- `total_results` reflects Mercari's full matching-result count for the query, not just `len(items)` (this endpoint returns the first page). - `original_price_cents`, `num_likes`, and `condition_code` are omitted from an item when Mercari's response doesn't include them for that listing. - `condition_code` and `num_likes` are best-effort field labels, recovered by decoding raw upstream responses rather than from a published schema — treat them as directionally useful, not authoritative. - A search with no matching listings returns `200` with `"items": []`. - A missing `query` returns `400` before any upstream request is made. Example response: ```json { "code": 200, "msg": "OK", "data": { "query": "nike jacket", "total_results": 21523, "items": [ { "id": "m31455228584", "url": "https://www.mercari.com/us/item/m31455228584", "title": "Nike varsity jacket. New with tags!", "thumbnail_url": "https://u-mercari-images.mercdn.net/photos/m31455228584_1.jpg?1784911712", "price_cents": 4873, "original_price_cents": 5400, "num_likes": 1931, "seller_id": "794269920", "created_at_unix": 1774057908, "updated_at_unix": 1784911712 } ] } } ```
Crawlora does not silently return bad data when the upstream page cannot be used.
| Status | Common failure case |
|---|---|
| 400 | Invalid input or missing required parameter |
| 429 | Plan or endpoint rate limit exceeded |
| 500 | Internal execution error |
| 502 | Upstream platform failed, returned unusable HTML, or served a challenge page that could not be resolved |
When possible, Crawlora returns structured error context so your integration can retry, back off, or inspect the request.
