# BestPrintOnDemand API

The BestPrintOnDemand API returns what it costs to print and ship print-on-demand products in the US across suppliers like Printful, Printify, and Gelato: base price, first-item shipping, and total, each with its source and date. It finds the cheapest like-for-like supplier, projects profit at a chosen sell price after a sales channel's fees, and reports the hourly price changes each supplier attributes to a product. Every endpoint is read-only, needs no key or account, and is open to any origin via CORS, and the data is licensed CC BY 4.0.

## For AI agents

Compare print-on-demand supplier costs in the US: base price, shipping, and total for a product, the cheapest supplier like for like, and profit after sales-channel fees. Read-only and keyless.

## Scope

Does not place orders, create products, or handle fulfillment. Use for print-on-demand supplier cost comparison only.

## Capabilities

- Find print-on-demand products available across suppliers like Printful, Printify, and Gelato
- Compare base price, first-item shipping, and total cost for a product across two suppliers
- Identify the cheapest like-for-like supplier for a given print-on-demand product
- Project profit at a chosen sell price after a sales channel's fees
- Read the hourly price changes each supplier attributes to a product
- Attribute each cost to its source and date for auditing a quote

## Use cases

### Agent-driven supplier selection

An AI agent picks the cheapest print-on-demand supplier before an order is placed. Through Jentic the agent searches for a product, pulls each supplier's base price, first-item shipping, and total, and returns the cheapest like-for-like option with the source and date behind every figure. Because the API is read-only and keyless, the agent needs no account to run the comparison.

Example prompt: Search for a 'unisex t-shirt', fetch its costs by supplier, and return the cheapest supplier with its base price, shipping, and total

### Margin check before listing

A seller decides what to charge by working backward from cost. The API projects profit at a chosen sell price after a sales channel's fees, using the supplier's base price and first-item shipping, so a store owner sees the margin on a product before publishing the listing. Each cost carries its source and date for a defensible quote.

Example prompt: Get a product's supplier costs, then compute profit at a $24.99 sell price after a sales channel's fees

### Price-change monitoring

Supplier prices move, and a reseller wants to catch the moves. The API reports the hourly price changes that Printful, Printify, and Gelato attribute to a product, so a monitoring agent can flag when a supplier raises a base price or shipping and re-run the cheapest-supplier comparison. The readings are timestamped and sourced.

Example prompt: Read the latest price changes, detect any supplier whose total rose, and re-compare that product across suppliers

## Why Jentic

- **Setup:** The BestPrintOnDemand API needs no key or account, so there is nothing to wire for auth, but by hand you still read its response shapes and parse each supplier's cost attribution yourself. Through Jentic you install once, import it from the API Directory, and your agent calls its read-only endpoints.
- **Permission scoping:** All four operations are read-only lookups and there is no path-scoped resource to pin, so you choose which operations your agent may call: it can search products and compare supplier costs but there is no write or delete operation on this API to expose.
- **Credential handling:** The BestPrintOnDemand API needs no key or account, so there is no credential for Jentic to hold. Your agent reaches its read-only, CORS-open endpoints directly at execution time.
- **Discovery method:** Agents search Jentic by intent such as 'compare print-on-demand supplier costs' or 'find the cheapest supplier', and Jentic returns the matching BestPrintOnDemand operation with its input schema so the agent calls the right endpoint without reading the reference docs.

- **Shopify** — Runs the storefront and sales channel whose fees feed the profit projection

## FAQ

### What authentication does the BestPrintOnDemand API use?

The BestPrintOnDemand API needs no API key or account per its OpenAPI spec: every endpoint is read-only and open to any origin through CORS. Because there is no credential, there is nothing for Jentic to inject, and your agent reaches the product, cost, and comparison endpoints directly.

### Can I compare two print-on-demand suppliers with the BestPrintOnDemand API?

Yes. The compare endpoint returns a head-to-head record for a product between two suppliers, with base price, first-item shipping, and total for each, plus the source and date behind every figure. The costs endpoint gives the same breakdown for a single product across all tracked suppliers.

### What are the rate limits for the BestPrintOnDemand API?

The OpenAPI spec does not specify rate limits. Check the provider's site at https://bestprintondemand.co for current limits before running high-volume comparisons.

### Is there a BestPrintOnDemand MCP server?

Yes, BestPrintOnDemand publishes an MCP server that mirrors its web pages. You can also connect the API directly through Jentic: your agent gets the full 4-endpoint surface without loading another server's tool definitions into its context, operations are discovered on demand, and your rules decide which of them the agent may call.

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

Yes. All four operations are read-only lookups, so you write a rule that allows just the ones the agent needs, such as product search and supplier comparison, and it can read prices and price changes but reach nothing else. Every call the agent makes is logged.

### How do I compare supplier costs with the BestPrintOnDemand API through Jentic?

Search Jentic for 'compare print-on-demand supplier costs' and it returns the comparison operation with its input schema; your agent passes a product and two suppliers and reads back base price, shipping, and total. To run it on your own infrastructure, install Jentic One from its GitHub repo.
