Data PAYMENT-READY

payment-ready until 2026-09-15

Korean automotive-electronics intelligence (jeonjang = vehicle E/E systems), sold per query. Structured feed of Korean auto-electronics news, analysis and KPIs - software-defined vehicles, ADAS, automotive semiconductors, in-vehicle networking, power electronics, and the Hyundai/Kia, Mobis, LG and HL Mando supply chains - written from Korean primary reporting English-language sources do not cover. FREE TIER: depth=index returns slug, date, category, title and facets at any limit with no payment, so you can browse the whole corpus before buying. Paid: brief (+summary +KPIs) $0.022/item, full (+body +sources) $0.11/item, plus a $0.01 base fee that is waived on cursor continuations. Empty results are free. Filter by date, category and keyword; content is Korean and common English terms are auto-mapped to Korean. USDC on Base or Polygon.

VERDICT

ranking generation 3

solid 86/100 #179 of 283 in Data by measured score

What the score read on this service: status online, 100% uptime 30d, 2464ms response p95, x402 compliance 14 of 14, $0.12 price against the category. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

It is a score inside Data, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 283 listings, this one among them. That set is wider than the 283 the position above is counted against, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

ALTERNATIVES IN DATA

Other Data services in this directory, ordered by the same measured score. The figures are ours: 30-day uptime from our own probes, 30-day settlement volume read on-chain (a conservative undercount, and null where we cannot measure it, never a zero).

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/jeonjang-korea-automotive-electronics-intel/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
