Why eBay Data Is Hard to Get

eBay's native APIs require app registration, OAuth flows, and developer approval. Rate limits are strict, and the API surfaces are fragmented across Browse, Finding, and Trading APIs with different auth schemes. Most teams end up maintaining brittle scrapers or skipping eBay data entirely — even though it's one of the richest sources of real transaction prices and marketplace intelligence available anywhere.

These endpoints fix that. No developer account, no OAuth dance, no scrapers to maintain. Pass an access-token header and get back clean JSON with listing details, actual sold prices, seller metrics, catalog data, and buyer reviews. All endpoints require an Anysite access-token header (no eBay OAuth on your side).

What You Can Build

Price Research & Sold History

Pull sold listings for any keyword to see what items actually clear at versus asking price. Feed historical sold prices into pricing models, reseller dashboards, or inventory valuation tools.

Seller Due Diligence

Assess a seller's trustworthiness before a bulk purchase or partnership. Combine the seller profile (feedback score, tenure, items sold) with their full feedback history to surface risk signals — all without an eBay developer account.

Catalog & PIM Enrichment

Hydrate internal product databases with catalog metadata (brand, MPN, UPC, specs, images) and buyer reviews from eBay's catalog — a structured layer that's hard to get from any other source.

Marketplace Monitoring

Track listing activity, pricing shifts, watcher counts, and inventory changes for a keyword or specific seller over time. Build alerts when a competitor drops prices or a high-value item lists below threshold.

Quick Start

  -H "access-token: YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "keyword": "vintage denim jacket",
    "condition": "used",
    "count": 50
  }'

Pull sold-price history

curl -X POST "https://api.anysite.io/api/ebay/items/sold" \
  -H "access-token: YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "keyword": "nike air jordan 1 chicago",

Pricing

Flat 10 credits for lookups, 10 credits per result batch for searches. All endpoints authenticate with an Anysite access-token header (no eBay OAuth on your side). Credits are shared across all Anysite endpoints.

Endpoint	Cost
`/api/ebay/categories`	10 credits
`/api/ebay/items`	10 credits
`/api/ebay/items/search`	10 credits per 50 results

Cost calculator hint: multiply the number of searches per day by 30 (days) and by 10 (credits per call) to estimate monthly usage. A daily price check (1 search/day, 50 results) = 300 credits/mo. 50 keywords checked twice daily = 30,000 credits/mo.

Estimated Monthly Usage

Use Case	Monthly Calls	Estimated Credits
Daily price check (1 items/search/day, count=50)	~30	300 credits/mo
Reseller tool (50 keywords × 2 endpoints × 30 days, count=50)	~3,000	30,000 credits/mo
Marketplace monitoring (200 keywords × ~2 endpoints × 30 days + seller checks)	~12,000+	120,000+ credits/mo

Frequently Asked Questions

Do I need an eBay developer account?

No. These endpoints work with your Anysite access-token only — no eBay app registration, no OAuth, no developer approval process. All endpoints require an Anysite access-token header (no eBay OAuth on your side).

How current is the data?

Listing search, sold history, and seller profiles are pulled live at request time. You always get the current state of eBay — not a cached snapshot.

Can I get historical sold prices going back months?

The /api/ebay/items/sold endpoint returns completed listings available through eBay's browse surface. Coverage depth depends on eBay's own retention window for completed listings.

What buying formats are covered?

Fixed-price, auction, best-offer, and buy-it-now. The buying_format field in search and sold results tells you exactly what type each listing is — including bid counts for auctions.

Can I filter searches by category?

Yes. Use /api/ebay/categories to get the category tree and resolve IDs, then pass a category ID as a filter to /api/ebay/items/search to scope results precisely.
