APIsec Bolt is a free Chrome plugin Bolt that turns live traffic and API docs into a clean, actionable inventory—without proxies, agents, or setup. You Get: Immediate visibility: See real API calls as you click around any site—no apps to install, no proxies to setup, no traffic rerouting. ‍ Signal over noise: Filters high‑confidence endpoints (not CSS, JS, images) so you can focus on what matters. ‍ Spec on demand: Export a well‑formed open API spec OpenAPI spec from observed traffic in one click. ‍Faster recon: Flip to Parameter Mode to enumerate parameters and where they’re used. ‍ Safe scoping: Set a base URL boundary (e.g., api.example.com) to keep discovery in-bounds. ‍ Authorized Testing Only — Use Bolt only on systems you own or have explicit permission to test.
