- **[A designer price drop alert](https://apiforagents.dev/platforms/farfetch/product-api).** For shoppers watching a piece. It reads the product each day and sends a note when the discount grows. Uses products and history.
- **[A size back-in-stock alert](https://apiforagents.dev/platforms/farfetch/product-api).** For shoppers waiting on a size. It reads per-size availability and flags when the size returns. Uses products.
- **[A sale page monitor](https://apiforagents.dev/platforms/farfetch/listings-api).** For deal newsletters. It reads a sale listing page and lists items that are new since the last run. Uses listing.
- **[A brand pricing report](https://apiforagents.dev/platforms/farfetch/search-api).** For brands and wholesale teams. It searches the brand name and reports prices and discounts across boutiques. Uses search.
- **[A boutique map for a designer](https://apiforagents.dev/platforms/farfetch/search-api).** For brand teams. It reads the seller boutique on each of the designer's products to see who carries what. Uses search and products.
- **[A markdown timing dataset](https://apiforagents.dev/platforms/farfetch/listings-api).** For analysts and buyers. It reads a category listing on a schedule and keeps the stored discount series, which is free. Uses listing and history.
- **[A resale pricing reference](https://apiforagents.dev/platforms/farfetch/search-api).** For resellers. It compares a piece's current price and full price with what they plan to ask. Uses search.
- **[A personal shopper agent](https://apiforagents.dev/platforms/farfetch/search-api).** For shoppers. An agent searches for a described item and keeps only pieces in their size and budget. Uses search and products.

## How to start

1. Sign up. An agent registers itself with one POST and starts with $0.10 of free credit; a person can sign up on the site instead.
2. Quote the first call for free: send the products request with "estimateOnly": true and read the price before anything is spent.
3. Run the same call with "maxUsd" set as a ceiling, and keep the rows it returns.
4. Schedule it: repeat the call daily or weekly, and read the stored series with history, which is free.

## Operations used

- [Farfetch Product API](https://apiforagents.dev/platforms/farfetch/product-api): $0.0009 per record. Full product detail for up to ten Farfetch product URLs or item ids.
- [Farfetch Listings API](https://apiforagents.dev/platforms/farfetch/listings-api): $0.0009 per record. Any designer, category or sale listing page URL.
- [Farfetch Search API](https://apiforagents.dev/platforms/farfetch/search-api): $0.0009 per record. Keyword search across Farfetch.

## Questions

### Can I read any listing page?

Yes. listing takes any designer, category or sale listing page URL and returns its products in page order.

### Do I need a Farfetch account to build these?

No. The API reads public data and never asks for your login, password or cookie.

### What does a run cost?

Farfetch records are priced from $0.0009 per record. A call can carry a minimum, so send it first with "estimateOnly": true. The quote is free and is the most the call can cost.

### Can an AI agent build and run these on its own?

Yes. It signs itself up with one call and gets $0.10 free, quotes each call before it spends, and pays from a prepaid balance. "maxUsd" caps every call, and only a person can add money.

## Why API for Agents

- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.

## Start

The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type. Open it at https://apiforagents.dev/dashboard/run (sign in first).
