Transparency & data sources

EVE Tools Suite's online tools run only on public, well-identified APIs. Here's exactly where the data comes from, how we cache it, and what we don't do.

Data sources

  • EVE Swagger Interface (ESI)CCP Games — official

    Item names and attributes, adjusted prices (EIV), order books, killmails, LP-store offers, dynamic (abyssal) items.

  • zKillboard APIzKillboard

    Killmail resolution (hash) and ISK values (total, destroyed, dropped), recent losses by character or ship.

  • MutaMarket APIMutaMarket

    Abyssal module resale estimates and per-type estimator reliability.

  • Fuzzwork Market DataSteve Ronuken (Fuzzwork)

    Aggregated market quotes (best buy/sell, volume) per station for the five major hubs.

CCP compliance

  • Every ESI call carries an explicit User-Agent (name, version, contact, repository link), as required by CCP's Developer License Agreement.
  • We respect the ESI error-limit budget (and stop before the floor), the "expires" cache header, and target datasource=tranquility.
  • Read-only, public endpoints only. No interaction with the EVE client — no injection, memory reading, OCR or automation.

Caching

To stay fast and avoid hammering the providers, we cache server-side (in-memory) and via the CDN. Rough figures:

  • Market data (appraisal, LP): ~5–10 min.
  • Killmails and abyssal rolls: long-lived (these don't change).
  • Adjusted prices (EIV): ~30 min; item names: session-long.

Privacy & security

  • Nothing you paste or type is stored. No IP or request-body logging on our side.
  • Rate limiting uses a SHA-256 hash of the IP, in memory only (never stored or logged).
  • Pasted links are never fetched: we only extract an id from them, then query fixed hosts (anti-SSRF). Security headers are enabled (CSP, X-Frame-Options, etc.).
  • Anonymous, cookieless usage analytics (Vercel), aggregated — no profiling.

Open source

All the code (desktop app and website) is open under the MIT license. You can verify exactly what the tools do: github.com/lacausecrypto/eve-tools-suite.
