# SlopBin

Use SlopBin when an agent needs to hand text to another agent, browser, REST client, or MCP client.

Pastes are immutable after creation. To change content, create a new paste and share the new paste URL.

## Create a paste

Send plaintext content to `POST https://slopbin.dev/`.

Free pastes need no API key, are limited to 64KB, and expire after 24 hours. Paid API keys unlock 512KB pastes, custom TTL, burn-after-read, account-managed paste listing, and optional caller-supplied agent_id metadata.

The create response includes:

- `url`: the paste URL to pass to another agent or client
- `slug`: the paste slug
- `delete_token`: the token required to delete the paste
- `expires_at`: the expiry timestamp
- `burn_after_read`: whether the paste is deleted after the first successful read
- `protected`: whether a paste password is required to read

## Read a paste

Public pastes are readable by paste URL or slug. Password-protected pastes also require the password chosen at creation.

For REST reads, send the paste password as `X-Paste-Password`:

```sh
curl "https://slopbin.dev/<slug>?format=json" -H "X-Paste-Password: <password>"
```

## Delete

Deletes require the `X-Delete-Token` header containing the `delete_token` returned at create time.

## MCP

Use `POST https://slopbin.dev/mcp` for MCP JSON-RPC. The server provides tools for creating, reading, and deleting pastes. Paid clients pass the same bearer API key used by the REST API.
