PaidTasks (WASM)

This is an example WASM extension you can use as a base to vibe code an extension that can be shared safely.

PaidTasks is an extension to share a list of tasks and have people pay you to complete the tasks.

Key Files

• config.json: permissions, public handlers, public KV keys, and payment tags
• wasm/: module.wat or module.wasm
• static/ and templates/: UI and public pages

Permissions (Current)

• ext.db.read_write
• api.POST:/api/v1/payments (policy: create-only, payments_out: false)
• ext.payments.watch

Payment Tags

This extension uses the tag paidtasks. Users must grant it in the permissions dialog.

AI Prompt (Copy-Paste)

You are building a LNbits WASM extension. First read:
extensions/wasm/docs/agents_wasm_extensions.md

Rules:
- Only edit files under lnbits/extensions/<ext_id>/.
- Use extensions/paidtasks as a base template.
- Any internal endpoint access must be declared in config.json permissions.
- For POST /api/v1/payments you must set "out" explicitly and declare policy.payments_out.
- Use <lnbits server>/openapi.json as the API reference.

Goal: <describe extension behavior>.

Test Checklist

1. Enable extension and grant permissions + paidtasks tag.
2. Create a list and tasks.
3. Open the public page and create an invoice.
4. Pay the invoice and verify:
   • Task is marked paid.
   • Public page updates via websocket.
