How this service works
Normalize public marketplace listing activity, offer, seller, condition and quantity hints. eBay credentials are optional configuration; no buying, bidding or seller mutation is supported. Base mainnet USDC
Output
Returns a normalized, structured representation of the public marketplace listing including activity state (active/ended/sold), offer details (price, currency), seller identity signals, item condition classification, and quantity/availability hints. eBay-optional credentials are accepted but not required; no transactional or mutation operations are performed.
Example use cases
Monitor listing availability before purchase
“Check this eBay listing at https://www.ebay.com/itm/987654321 and tell me if it's still active, what condition the item is in, and how many are left in stock.”
Compare seller signals across listings
“I'm looking at two marketplace listings — https://www.ebay.com/itm/111111111 and https://www.ebay.com/itm/222222222 — can you extract the seller details and offer info from the first one so I can evaluate the seller's reputation?”
Validate listing data for price tracking
“Normalize this public marketplace listing at https://www.ebay.com/itm/333333333 and give me the structured offer price, condition, and quantity hints so I can log it in my price tracker.”

Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/marketplace/listing-state?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a normalized, structured view of a public marketplace listing's current state — including offer, condition, seller, and quantity — without performing any transaction. Prefer this over raw web scraping when you need consistent, structured output across multiple marketplace listing URLs. Best suited for price monitoring, seller research, inventory checking, and comparison workflows where read-only listing data is sufficient.
Side effects
- URL is not a public marketplace listing — returns error or empty state
- Listing has expired or been removed — may return ended/unavailable state
- Marketplace blocks automated inspection — returns access-denied or empty response
- Malformed or non-HTTP(S) URL — rejected by input schema pattern validation
- Marketplace returns dynamic/JS-rendered content that cannot be parsed statically
