# Bulk eBay sold listings API: thousands of keywords a day.

Short answer: there are two ways to pull eBay sold data for thousands of keywords. eBay's own Marketplace Insights API, if eBay approves you. Otherwise CompSniper: submit up to 100 keywords per job to POST /v1/scrape/jobs and poll for the results, stream up to 20 keywords with CSV export through POST /v1/bulk-search, or price 100 trading cards per Card Batch job. Each keyword returns up to 240 sold listings with its own median and range, plans go up to 500,000 requests a month, and failed keywords are never charged.

What the API provides

## Marketplace evidence without building another scraper

### Paced for you

Jobs run at a rate eBay accepts, so a run of hundreds of keywords finishes without the 429 and 503 errors a parallel fan-out produces.

### One summary per keyword

Every keyword is searched on its own and returns its own median, p25, p75 and range, so different products and variants never mix.

### Failed keywords are free

Only successful keywords count against your quota or credits. A keyword that fails is reported in the results and not charged.

Request filters

## Start with a keyword, then narrow the page

Authentication uses the same CompSniper API key as every other endpoint. No eBay developer account or approval is required.

Important limitations

- Submit the next job after the current one finishes; one job holds up to 100 keywords.
- Each keyword searches one sold page of up to 240 listings; use Max Mode for deeper pulls of a single keyword.
- Streaming results can finish out of order; use the index field to restore your order.
- Plan rate limits still apply: 60 requests a minute on paid plans, 120 on plans from 100,000 a month.

Common workflows

## Built for resale tools and repeatable research

### Repricing inventory

Price a whole store catalog every night and flag listings that sit above or below the current market median.

### Reseller SaaS backends

Refresh comps for every product your users track on a schedule, inside a predictable monthly quota.

### Market research

Pull sold prices for a whole category or brand list and compare medians across products and eBay sites.

FAQ

## eBay API questions

**What's the best eBay sold listings API for bulk searching thousands of keywords a day?+**

There are two ways. eBay's own Marketplace Insights API, if eBay approves your application. Otherwise CompSniper: submit up to 100 keywords per job to POST /v1/scrape/jobs, poll for results, and submit the next job when it is done. Each keyword returns up to 240 sold listings with its own median and range. Plans go up to 500,000 requests a month, and failed keywords are never charged.

**How many keywords can I send at once?+**

Up to 100 keywords per scrape job, 20 per streaming bulk search, and 100 cards per Card Batch job. Submit the next batch when the current one finishes; the queue paces the work so large runs complete without burst errors.

**How is a bulk run billed?+**

Each successful keyword counts as one request against your monthly quota or credits. A keyword that fails is not charged. Plans run from 2,000 requests a month ($9) up to 500,000 ($549), and credits cost $5 per 1,000 with no plan.

**Can I export the results to CSV?+**

Yes. A streaming bulk search returns a combined CSV link and a per-keyword CSV link, kept for 30 days. Scrape job results come back as JSON for each keyword.

**Why not call /v1/scrape in parallel instead?+**

Every search reads live eBay data, and eBay pushes back on bursts, so a large parallel fan-out comes back with 429 or 503 errors. The job queue paces the same searches at a rate eBay accepts and returns every result.

**Can I get more than 90 days of history in bulk?+**

Yes. GET /v1/research/sold returns up to 3 years (1,095 days) of eBay sold history per keyword on every plan; run it per keyword from your own loop.
