## Filebin

- `storage/filebin` | fails-quota | evidence reported | binding retention-clamped | category anonymous-dump
- identity a placeholder: card and phone unknown | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://filebin.net
- free tier: no account; per-bin, no published byte cap; bins expire 6 days after creation | unit: mixed | metered on: unstated | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: no account; per-bin, no published byte cap; bins expire 6 days after creation | days: 6 | source: [1] | note: not stated
- egress: unmetered; downloads redirect to a signed S3 URL (Backblaze-style hel1-dc4) | metered: no
- identity: anonymous
- interface: rest
- limits:
  - retention-clamped (binding): expire 6 days [1]
  - retention-clamped (binding): retention from bin creation ('deleted automatically 6 days [1]
- limits note: 6-day retention from bin creation ('deleted automatically 6 days from now' on the create page). Bin is created implicitly by the first PUT.
- interface detail: rest
- tooling: plain HTTP PUT — 'curl -X PUT --data-binary @file -H "filename: probe.bin" https://filebin.net/<bin>/probe.bin'. Open source (github.com/espebra/filebin2, BSD-3) so it can be self-hosted.
- composes with: unlimited distinct bin IDs, each with its own 6-day clock — 'N bins x 6 days' is the only multiplication, and nothing survives week 2.
- reliability: IMPORTANT INVERSION: a real browser UA (Mozilla/...) gets a 5399-byte 'are you sure / proceed to download' interstitial at HTTP 200; curl's default UA gets the real bytes. Automation works better than a browser here — the opposite of the usual trap. Any client that sets a browser UA (rclone, most HTTP libs, headless Chrome) will silently receive HTML instead of the file.
- notes: the same as the free tier
- extras:
  - dead_end.failure_class: retention
  - dead_end.why: no account; per-bin, no published byte cap; bins expire 6 days after creation
