Changelog

Changes to the API and docs, newest first. Changes are additive; existing fields are not removed. Atom feed: degisiklikler.xml.

#October 17, 2026

• Quick lookup — New GET /api/v1/ara/: instant candidates from the Ulawk index (name, registry office, registry number, legal form, status, province, address, incorporation, latest notice date) with eslesme (tam · yakin · kismi) and skor. No live registry lookup, nothing is followed; no personal names. Form prefill guide: the server-to-server pattern.
• Verification report — New GET /api/v1/sirketler/{id}/dogrulama-raporu.pdf: a sealed PDF from the sourced profile (DOGRULANDI · KISMI · DOGRULANMADI), every fact with its notice reference and verbatim quote; ?bicim=json|html, free re-download with ?rapor=DR-…, ?tam_zorunlu=1 → 409 veri_eksik.
• Signing check — New GET|POST /api/v1/sirketler/{id}/imza-kontrol/: yetkili · yetkili_degil · belirsiz for a person, date, amount and transaction; reasons, rules applied and co-signers, each with its source notice. Available in the sandbox with DENEME-… companies.
• Minimum capital signal — New asgari_sermaye signal in uyum_sinyalleri: the latest published capital is compared with the statutory minimum for joint-stock and limited companies (Turkish Commercial Code arts. 332, 580, provisional art. 15). Unknown capital gives aktif: null; capital meeting the minimum gives false. Not legal advice.
• Changelog feed — An Atom feed of this changelog: /en/gelistirici/degisiklikler.xml (Turkish at /gelistirici/degisiklikler.xml).
• Status subscription — E-mail subscription on the /durum/ page: a message when a component has an outage and when it recovers; double opt-in, an unsubscribe link in every message.
• UK filing evidence — In UK profiles, officer, shareholder, capital and address rows link to a verbatim quote from the filed document and its place in that document.
• France filings — French profiles gain shareholders and share counts, capital history and articles of association from filed documents; every record carries its quote from the document.
• Japan register — Japan is now covered: identity, address and financial statements from the official company register; details in the Japan country guide.
• Add by tax certificate — In the app, add companies from a list of names or from tax certificate PDFs: candidate records are found without the registry number and added after review.

#October 16, 2026

• **veri_durumu** — Completeness, method and limits per profile section; the empty-list rule ([] = looked, none · null = not available).
• **hata_ayrinti** — Structured detail in every error body: kod, mesaj, taraf, kaynak, tekrar_denenebilir, tekrar_sn; Retry-After on 429 and retryable errors.
• Change categories — A fixed kategori on every change row and notice; kategoriler= filter on change and notice endpoints.
• Webhooks — Change webhooks by category: /api/v1/webhooklar/ (create, list, update, delete, test); the signed body carries the notice itself.
• Sandbox — Sandbox keys see made-up DENEME-… companies and never touch live data or your allowance. Special ids cover preparation, source outage, liquidation, strike-off and pagination.
• Access by id — Company endpoints also accept string ids (/api/v1/sirketler/DENEME-100001/): DENEME-… ids in the sandbox; numeric ids with live keys.
• MCP — Ulawk MCP server (/mcp/): AI assistants read the companies you follow through tools.
• Coverage catalogue — Public, keyless /api/katalog/ and /api/katalog/{kod}/: coverage by country. Service status at /durum.json.
• Developer docs — This site: OpenAPI 3.1 definition (/gelistirici/openapi.json), a Markdown version of every page and llms.txt.
