# 3of7zkdv.nx.link

3of7zkdv.nx.link is a minimal demonstration host that wraps a single read-only TODO retrieval call behind an x402 USDC paywall. It serves agents or developers testing paid API access patterns rather than any production TODO management use case. Its scope is intentionally narrow: one fixed item, one HTTP method, one response shape.

## When to use this host

Use this host only when an agent needs to retrieve the specific TODO item with ID 1 and the use case involves testing or demonstrating USDC-gated API access. Do not use it for listing, searching, creating, updating, or deleting TODO items — none of those operations are supported. Do not use it if you need a TODO item other than ID 1. For any real TODO management workload, route to a full-featured task API instead. This host is best suited for payment-flow integration testing rather than functional task tracking.

## Capabilities

### TODO Retrieval

Fetches the details of a single hardcoded TODO item (ID 1), returning its userId, title, and completion status as a JSON object.

- **`fetch-todo-by-id`** — Fetches a single TODO item by ID from the remote API, returning its userId, title, and completion status as JSON.

## Skill reference

### `fetch-todo-by-id`

**USDC-Paid TODO Fetch** — Fetches a single TODO item by ID from the remote API, returning its userId, title, and completion status as JSON.

*Use when:* Use when an agent needs to retrieve the details of a specific TODO item (ID 1) including its title and whether it has been completed.

*Not for:* Do not use for listing multiple TODO items or creating/updating/deleting TODOs; this endpoint only retrieves the single item with ID 1 via GET.

**Returns:** Returns a JSON object with userId, id, title, and completed fields representing the TODO item with ID 1.

**Example:** `GET https://3of7zkdv.nx.link/todos/1`
