How the Yahoo! Flea Market Japan API works

Yahoo! Flea Market Japan is a normal ReefAPI surface — the same four rules that hold for every other engine on the key.

01
Authenticate
x-api-key header

No OAuth app, no request signing, no per-site account. One key covers all 438 engines.

02
Call
POST /paypay-flea-market/v1/…

Every route is a POST with a JSON body. Parameters are validated against the published schema before anything is charged.

03
Pay
3 credit per call

Credits, not seats. Failed and blocked calls are never charged, and cache hits cost nothing.

04
Read
{ ok, data, meta, error }

One envelope everywhere. meta carries latency_ms, record_count and the endpoint that answered.

Find and follow a listing

Keep the identifier from a current search.

01search
POSTsearch

Pass query, inspect match_type, then copy results[].id.

02product/detail
POSTproduct/detail

Pass that identifier as item_id.

Read the asking price in yen, description, images and published seller and shipping facts.
