API

Create paste

curl -X POST http://localhost:8080/api/pastes \
  -H "Content-Type: application/json" \
  -d '{
    "content": "print(hello)",
    "title": "my snippet",
    "language": "python",
    "expires_in": "168h",
    "password": "optional",
    "custom_slug": "optional",
    "burn_after_read": false,
    "visibility": "public"
  }'

Response includes id, url, raw_url, api_url, and a one-time deletion_token.

Get paste

curl http://localhost:8080/api/pastes/{id}
# password-protected pastes:
curl "http://localhost:8080/api/pastes/{id}?password=secret"
# or via header: X-Paste-Password: secret

Raw content

curl http://localhost:8080/raw/{id}

Soft delete

curl -X DELETE http://localhost:8080/api/pastes/{id}

Hard delete (requires deletion token)

curl -X DELETE "http://localhost:8080/api/pastes/{id}/redeem?token=TOKEN"

Public history

curl "http://localhost:8080/api/public?limit=25&offset=0"

Create can (bundle of items)

curl -X POST http://localhost:8080/api/pastes/can \
  -F "title=My bundle" \
  -F "expires_in=48h" \
  -F 'json_items=[{"title":"notes.txt","content":"some notes"}]' \
  -F "files=@screenshot.png" \
  -F "files=@log.txt"

Get can + items

curl http://localhost:8080/api/cans/{id}
curl http://localhost:8080/api/cans/{id}/items/{item_id}

Expiry and deletion

• Expired pastes are soft-deleted by a background sweeper (runs every minute).
• Soft-deleted pastes are hard-deleted after a 7-day grace period.
• Deletion tokens allow immediate hard delete.
• Burn-after-read pastes are soft-deleted on first read.

Web pages

• /new — create a paste
• /history — public paste history
• /{id} — view a paste
• /unlock/{id} — password gate for protected pastes
• /raw/{id} — raw content with original content type
