Soldgraph API examples

Copy-paste examples for the Soldgraph resale data API: eBay, Poshmark and Mercari sold listings as JSON, plus active listings from Depop, Whatnot, OfferUp and Facebook Marketplace and Vinted, and TCGplayer card prices.

Use it to replace eBay's retired findCompletedItems. You don't need an eBay developer account.

from soldgraph import search  # python/soldgraph.py

result = search("/ebay/sold", {"q": "nintendo switch oled"})
for row in result["data"]:
    print(row["sold_date"], row["displayed_price"], row["title"])

Get a free key: 100 free requests, no credit card required.

Run one

export SOLDGRAPH_KEY=sg_...

# Python
cd python && pip install -r requirements.txt && python ebay_sold.py "nintendo switch oled"

# Node
node node/ebay-sold.mjs "nintendo switch oled"

# curl
./curl/ebay-sold.sh "nintendo switch oled"

How the API works

A search either returns its result right away or a job to poll. The clients in python/ and node/ handle that, plus retries and idempotency. If you're writing your own, read AGENTS.md first.
