# Introduction

> PCI Booking tokenization platform. Capture, store, and process payment cards without PCI DSS scope on your servers.

## What Is PCI Booking?

PCI Booking is a **tokenization service** that outsources your PCI DSS compliance. We securely capture, store, and send payment card data so you never have to touch it.

You integrate once. We handle the card data. You work only with tokens.

## Three Core features

| feature                                      | What It Does                                                                                                                                                             |
| -------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **[Capture Cards](/capture-cards/overview)** | Capture card data through hosted forms, email/SMS links, client-side libraries, file uploads, or migration and receive a token back.                                     |
| **[Manage Cards](/manage-tokens/overview)**  | Query token details, update expiry dates, manage CVV, set permissions, run risk checks, or delete tokens.                                                                |
| **[Use Tokens](/use-tokens/overview)**       | Send card data where it needs to go: to a PSP for payment processing, to a partner via HTTP relay, via batch file delivery, or displayed securely to an authorized user. |

Processing a payment is simply **detokenization**. PCI Booking replaces the token with real card data and sends it to the PSP on your behalf.

## AI Agent Integration

Building an AI agent or tool that needs to work with PCI Booking? We publish machine-readable documentation following the [llms.txt convention](https://llmstxt.org/) in two formats:

| File                                                                | Size     | Best For                                                                                                                                                                                                                                                        |
| ------------------------------------------------------------------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [`/llms.txt`](https://developers.pcibooking.net/llms.txt)           | \~4 KB   | A lightweight index with page titles, short descriptions, and links. Use this when your LLM can follow URLs or when you only need to find the right page.                                                                                                       |
| [`/llms-full.txt`](https://developers.pcibooking.net/llms-full.txt) | \~550 KB | The full content of all 160+ documentation pages in a single file. Use this when your LLM needs the actual content upfront without making additional requests. Note: this is a large file and may consume a significant portion of your model's context window. |
