### AI Agent Integration via Jentic

AI agents discover and call Walmart Marketplace endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle bearer tokens manually.

Example prompt: Search Jentic for 'all items', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring Walmart Marketplace by hand means learning its bearer token auth, pointing at the marketplace.walmartapis.com host, and attaching the token to every request yourself. Through Jentic you install once, import Walmart Marketplace from the API Directory, store the token once, and your agent calls it.
- **Permission scoping:** Walmart Marketplace puts the resource id in the URL path (/v3/items/{itemId} and /v3/orders/{purchaseOrderId}), so a rule can pin your agent to one item or order. You choose the operations it may call, so you can allow reading items and orders while a destructive one like deleting an item is not included unless you add it.
- **Credential handling:** Your Walmart Marketplace token is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
- **Discovery method:** Agents search Jentic by intent such as 'list all items' or 'get an order by purchase order id', and Jentic returns the matching Walmart Marketplace operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Walmart Marketplace use?

The Walmart Marketplace uses a Bearer token in the Authorization header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.

### Can I all items with the Walmart Marketplace?

Yes. Use the GET /v3/items endpoint. The API returns structured JSON responses that agents can parse and act on directly.

### What are the rate limits for the Walmart Marketplace?

Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.

### How do I all items through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'all items'. Jentic returns the matching Walmart Marketplace operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Walmart Marketplace have?

The Walmart Marketplace exposes 9 endpoints covering inventory management, item management, order management operations.

### Can I limit what my agent is allowed to do with the Walmart Marketplace API?

Yes. Because you run Jentic One yourself, your own rules decide which Walmart Marketplace operations and credentials the agent may use. You can allow read calls like GET /v3/items and GET /v3/orders while excluding a destructive operation such as DELETE /v3/items/{itemId} unless you explicitly add it. Since the resource id lives in the URL path, such as /v3/items/{itemId} and /v3/orders/{purchaseOrderId}, a rule can also pin the agent to a single item or order.
