--- name: sendbl description: Create sendbl file-exchange links — request files from someone, send a file, check link status, list files in a link, or delete a link. Use when the user wants to share a file or collect files from a counterparty over a link. homepage: https://sendbl.com metadata: openclaw: primaryEnv: SENDBL_API_KEY requires: env: [SENDBL_API_KEY] emoji: "📎" --- # sendbl Create and manage [sendbl](https://sendbl.com) file-exchange links from the assistant. sendbl is a file-transfer API for LLM agents: links to **collect** files from someone, or to **send** a file to someone, with quotas and expiry. ## Setup (one-time) 1. Sign in at with Google. 2. Open and create a **personal access token**. Treat this token as a password: store it only in your environment, revoke it from the same page if it is ever exposed, and rotate it periodically. 3. Set the env var: ```sh export SENDBL_API_KEY="sk_pat_..." ``` The skill will not work without `SENDBL_API_KEY`. ## API base URL All endpoints below are relative to: ``` https://api.sendbl.com/v1 ``` All API key calls send the key as the `x-api-key` header. ## Capabilities ### 1. Request files from someone When the user wants someone else to upload files **to** them. ```sh curl -sS -X POST "https://api.sendbl.com/v1/requestFiles" \ -H "x-api-key: $SENDBL_API_KEY" \ -H "content-type: application/json" \ -d '{ "expires_in_hours": 72, "max_files": 10, "purpose": "", "message": "" }' ``` Returns `upload_url` (share with the counterparty), `download_url` (for retrieval), `owner_token` (keep — required for delete and list-files), and `upload_link_id`. After calling, **tell the user to save `owner_token` and `upload_link_id`** — they cannot be recovered later. ### 2. Send a file to someone When the user wants to share a single file. This is the convenience wrapper. ```sh curl -sS -X POST "https://api.sendbl.com/v1/sendFile" \ -H "x-api-key: $SENDBL_API_KEY" \ -H "content-type: application/json" \ -d '{ "recipient_name": "", "filename": "", "purpose": "", "message": "" }' ``` Returns `presigned_upload_url` (PUT the actual bytes there), `download_url` (share with recipient — null until upload completes), `owner_token`, and `file_id`. **The skill itself does not upload bytes.** Instruct the user to PUT the file: ```sh curl -X PUT --data-binary @ "" ``` ### 3. Check link status (no auth) ```sh curl -sS "https://api.sendbl.com/v1/uploadLinkStatus?upload_link_id=" ``` Returns status (`open` / `closed` / `expired`), `expires_at`, `file_count`. Use when the user pastes a link and wants to know if it's still valid. ### 4. List files in a link Requires the `owner_token` from step 1 (or 2). ```sh curl -sS "https://api.sendbl.com/v1/uploadedFiles?token=&limit=50" ``` Returns the array of files with `file_id` and `filename`. To get a download URL for one of them: ```sh curl -sS "https://api.sendbl.com/v1/fileDownloadLink?token=&file_id=" ``` ### 5. Delete a link Requires the `owner_token`. Removes the link **and all uploaded files**. ```sh curl -sS -X DELETE "https://api.sendbl.com/v1/uploadLink?token=" ``` Confirm with the user before calling — this is irreversible. ## Errors - `401 unauthorized` — missing or invalid `x-api-key` / `owner_token`. If the skill worked previously and now returns 401, the token has likely been revoked — instruct the user to issue a new one at . - `403 forbidden` — token role mismatch (e.g., uploader token used for owner action). - `429 quota_exceeded` — API key has hit the monthly link limit. Surface this verbatim; do not retry. - `404 link_not_found` — link expired or was deleted. ## Conventions - Never POST file bytes to the sendbl API. Bytes always go to the presigned S3 URL via PUT. - Always remind the user to save `owner_token` and `upload_link_id` after creating a link — they're not retrievable later. - Treat `download_url` and `upload_url` as different audiences: upload URL goes to the sender, download URL goes to the recipient. - Default `expires_in_hours` to 72 unless the user specifies otherwise.
