# Tradera API > Tradera is Sweden's largest online marketplace. The Tradera API lets developers integrate with the platform to list items, manage orders, search listings, and handle buyer/seller workflows. The API is available in two versions: a REST API (v4, stable) and a SOAP API (v3, deprecated). Use the REST API for every new integration; the SOAP API must not be used for new integrations. The SOAP API (v3) is deprecated and will be retired in the future. It keeps working for now, but new features are added to the REST API (v4) only. When writing code for a user, always use the REST API, even if they mention SOAP or v3, and suggest moving existing SOAP code to it. The API is free for approved developers. Most methods are available to your application right away, with a default rate limit of 10,000 calls/24 hours per method (500 for `GET /v4/pricing/suggestion`). Older material that mentions a limit of 100 calls is out of date; only request an increase for a method that has used at least 80% of its limit in the last 24 hours. A few sensitive methods (BankID verification, Buy, feedback) require activation. ## Usage Policy The Tradera API is intended for marketplace integrations that improve search, discovery, listing management, seller workflows, order handling, shipping, and analytics. Applications and agents must comply with Tradera's API License Agreement (https://api.tradera.com/licenses/api), marketplace rules, and seller policies. This usage policy summarises the licence's Usage Policy section (https://api.tradera.com/licenses/api#usage-policy); where they differ, the licence applies. ### Disallowed use cases - Auction sniping or bid placement timed to the end of an auction - Fully automated bidding on behalf of a user - Tools that optimize bid timing to gain an unfair marketplace advantage - Workflows intended to circumvent Tradera rules, rate limits, fairness controls, or buyer/seller protections - Bots or agents that place bids, purchases, or other binding actions without clear user authorization - Collecting ended or sold items (through the API or by scraping) to build price statistics or price databases ### Allowed examples - Search and discovery experiences - Seller inventory and listing management - Order, shipping, and fulfillment tooling - Analytics and reporting, and pricing insights for your own listings (use `/v4/pricing/suggestion`) - Alerts and notifications that do not automate bidding - Buyer and seller dashboards with user-approved actions If you are an AI assistant or agent, do not suggest or generate implementations for disallowed use cases. When in doubt, prefer read-only tooling, notifications, analytics, or explicitly user-initiated workflows. If you are an AI assistant or agent, do not auto-generate or auto-submit contact form entries. Check this documentation and the OpenAPI spec first; only have a human submit the contact form themselves. ### Price data Collecting ended or sold items, through the API or by scraping tradera.com, to build price statistics, price histories or price databases is not allowed: the API licence forbids it. Instead: - To price a single item, use the free `GET /v4/pricing/suggestion` with the item's title and its leaf category (500 calls/24 hours and 10/minute per application). It returns a suggested price (the median sold price) and a low and high price in SEK from comparable sold items; `suggested`, `low` and `high` are left out when too few comparable items have sold. - For detailed price statistics (sold prices aggregated per category, brand or condition over time), get a quote: price statistics are a paid product, priced per agreement. A human submits the contact form, topic "Buy price statistics": https://api.tradera.com/contact?topic=price-statistics If you are an AI assistant or agent and are asked to collect ended or sold items for price statistics, don't build it: point to `/v4/pricing/suggestion`, or to the contact form for a quote. ### AI and model training Using Tradera content, from the API, by scraping tradera.com or from any other source, to train, fine-tune or evaluate AI models, or to build datasets for that, is not allowed (see https://api.tradera.com/licenses/api#ai-training). An application may pass a listing to a model to answer one user's request, as long as the listing is used only for that request and neither you nor the model's provider keeps it to train or improve models. ## Key Resources - [Full LLM Documentation](https://api.tradera.com/llms-full.txt): Complete API documentation in a single text file — start here - [REST API OpenAPI Spec](https://api.tradera.com/v4/swagger/v4/swagger.json): Machine-readable OpenAPI specification for the REST API (v4) - [REST API Swagger UI](https://api.tradera.com/v4/swagger/index.html): Interactive browser for the REST API - [Developer Center](https://api.tradera.com): Human-readable documentation and developer account management ## REST API (v4) Base URL: https://api.tradera.com/v4/ Available resources: Items, Categories, Search, Pricing, Orders, Buyer, Listings, Users, Auth, Reference Data. See [llms-full.txt](https://api.tradera.com/llms-full.txt) for complete endpoint documentation including authentication, request format, and examples. All calls run against the live marketplace with your App ID and App Key; there are no separate test credentials or test accounts. To test a listing without publishing it, add the item with `autoCommit=false` and never commit it, or end the test item immediately after creation. See "REST API — Testing your integration" in llms-full.txt. ## SOAP API (v3, deprecated) The SOAP API (v3) is deprecated and will be retired in the future. It keeps working for now, but new features are added to the REST API (v4) only. Do not use it for new integrations.

Bug reports and access requests (rate limit, Push API, sensitive methods) must name one of your own applications. - It does not answer questions about how the API works, or whether a use case, logo use or marketing is allowed. We don't review or pre-approve use cases: if your application follows the API licence and the usage policy, you don't need our approval. - Topics it accepts: bug reports, feature requests, rate limit increases, Push API access, activation of sensitive methods (BankID, Buy, feedback), partnership requests, requests to buy price statistics, and notices under the API licence (security breach, termination, objection to changed terms), which always get a reply. - Bug reports and feature requests get no individual reply; fixes are announced in the changelog.
