Terms of Service

These Terms of Service ("Terms") govern your use of the PikaQian website at pikaqian.com and the PikaQian API (together, the "Services"), operated by PikaQian ("PikaQian", "we", "us"). By creating an account, generating an API key, subscribing to a plan or otherwise using the Services, you agree to these Terms. If you do not agree, do not use the Services.

If you use the Services on behalf of a company or other organization, you agree to these Terms on its behalf and confirm you have the authority to do so.

• You must be at least 13 years old to use the Services, and at least 18 (or the age of majority where you live) to purchase a paid plan.
• You are responsible for keeping your account credentials and API keys confidential and for all activity under your account or keys. Do not share keys or embed them in client-side code that others can read.
• Notify us at admin@pikaqian.com if you believe a key has been compromised. You can revoke and regenerate keys from your account settings at any time.
• One account per person or organization. Creating multiple accounts to get around rate limits or quotas is not allowed.

Subject to these Terms and your plan, we grant you a limited, non-exclusive, non-transferable, revocable license to access the API and use the data it returns ("PikaQian Data") — including set and card metadata, prices, sales, population reports and sealed product data — as follows:

• Free and Hobby plans — personal, non-commercial projects, and evaluating or developing an integration. Attribution is required (see Section 4).
• Pro and Business plans — commercial use, including displaying PikaQian Data in public, paid or subscription applications and websites, internal business tools, and derived works such as valuations, analytics and portfolio tracking. Attribution is not required.

"Commercial use" means any use that generates revenue or supports a business, whether directly (a paid app, subscription, ads) or indirectly (a tool used to run a store, a selling operation or a service for clients). If you are unsure which plan you need, email us.

On every plan, you may:

• Cache and store PikaQian Data in your own database, and serve your users from that cache instead of calling the API for every request. We encourage it.
• Normalize PikaQian Data and combine it with data from other lawfully obtained sources.
• Keep PikaQian set and card IDs as external references in your own catalog.

Data retention after your subscription ends is covered in Section 6.

If you display PikaQian Data on a Free or Hobby plan, you must credit PikaQian with a visible link to the corresponding card's page on pikaqian.com wherever that card's data appears:

https://pikaqian.com/cards/{card_id}

Use the card's id from the API. For data that isn't tied to a single card (for example, a set list), link to the set's page at https://pikaqian.com/sets/{set_id}. Text such as "Prices by PikaQian" or "Data from PikaQian" is fine. Links must be visible to users and must not use rel="nofollow" or be hidden.

Attribution is optional on Pro and Business plans.

You may not, and may not help anyone else to:

• Redistribute, resell or sublicense PikaQian Data in raw or bulk form — including through your own public API, data feed, downloadable dataset or file export — without meaningful modification or our prior written permission.
• Use PikaQian Data to build or supply a competing Simplified Chinese card catalog, pricing API or data product.
• Scrape, crawl or bulk-download the pikaqian.com website. Use the API instead.
• Get around rate limits, monthly quotas, tier restrictions or billing — for example by rotating keys, sharing keys or creating multiple accounts.
• Interfere with or disrupt the Services, probe them for vulnerabilities, or send excessive, abusive or unusually patterned traffic.
• Use the Services for anything unlawful, or represent PikaQian Data as officially endorsed by The Pokémon Company or any marketplace.

If your paid subscription ends, or you move to a lower plan:

• You may keep set and card catalog metadata (names, numbers, rarities, variants, card text and IDs) you retrieved while subscribed, and derived works that don't reproduce the underlying records — such as image fingerprints or descriptors used for card recognition, and aggregated analytics.
• You must delete within 30 days any cached prices, individual sales records, population reports and sealed product prices that your new plan (if any) does not include, along with any cached card images.

Data obtained while subscribed may not be used to keep offering paid-tier features after the subscription ends.

Pokémon, the Pokémon Trading Card Game, card names, artwork and images are trademarks and copyrights of Nintendo, Creatures Inc., GAME FREAK inc. and The Pokémon Company (and, for Simplified Chinese releases, their licensees). PikaQian is not affiliated with, endorsed by or sponsored by any of them, and does not claim ownership of their intellectual property.

Card and product images returned by the API are provided for convenience. We do not own the rights to them and cannot grant you any license to them. Any display, caching or other use of images is at your own discretion and risk. Image URLs may change, so we strongly encourage caching images on your side rather than hotlinking.

PikaQian Data is compiled from publicly available sources, including public marketplace sales. We are not affiliated with eBay or any other marketplace.

Prices are estimates calculated from past sales and may be incomplete, delayed or wrong — for example, sales can be misattributed to the wrong card, and cancelled or refunded orders are not visible to us. PikaQian Data is provided for informational purposes only and is not financial, investment, grading or authentication advice. Do not rely on it as the sole basis for buying, selling or valuation decisions. If you find an error, please let us know and we will do our best to fix it.

• Paid plans are billed monthly in advance through Stripe and renew automatically until cancelled. Current prices and quotas are listed on the pricing page, and rate limits in the API docs.
• You can cancel at any time from Billing & Plan. Cancellation takes effect at the end of the current billing period, and you keep access until then.
• Except where required by law, payments are non-refundable. We may consider refund requests case by case at our discretion — email us.
• If a payment fails, your access may be downgraded or suspended until it is resolved.
• We may change prices, quotas or plan features. We will give at least 30 days' notice of a price increase to existing subscribers, and the change applies from your next billing period.

The Services are provided on an "as available" basis without any uptime guarantee or service level agreement. We may add, change or remove endpoints, fields or features, perform maintenance, or adjust rate limits. We will try to give notice of breaking API changes in advance when practical. Card and set IDs are intended to remain stable.

You can stop using the Services and cancel your plan at any time. We may suspend or terminate your access, or revoke API keys, if you breach these Terms, fail to pay, create a security risk, or if required by law. Where reasonable, we will contact you first. On termination your license ends, and Section 6 applies to any data you have stored. Sections 5 through 8 and 12 through 16 survive termination.

The Services and PikaQian Data are provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, completeness, non-infringement, or uninterrupted or error-free operation.

To the fullest extent permitted by law, PikaQian will not be liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill, arising out of or related to the Services. Our total liability for any claim relating to the Services will not exceed the greater of the amount you paid us in the twelve (12) months before the event giving rise to the claim, or $100 USD.

You agree to indemnify and hold PikaQian harmless from any claims, losses and expenses (including reasonable legal fees) arising from your use of the Services or PikaQian Data, your breach of these Terms, or your violation of any third party's rights, including intellectual property rights in card images.

These Terms are governed by the laws of the State of Illinois, USA, without regard to its conflict-of-law rules. Any dispute will be brought exclusively in the state or federal courts located in Illinois, and you consent to their jurisdiction. Before filing any claim, please contact us so we can try to resolve it informally.

• We may update these Terms. Material changes will be announced on this page, with an updated effective date, and by email to account holders when practical. Continuing to use the Services after a change means you accept the updated Terms.
• These Terms are the entire agreement between you and PikaQian about the Services, unless we have signed a separate written agreement with you (such as an enterprise agreement), which takes precedence where the two conflict.
• If any provision is found unenforceable, the rest remains in effect. Our not enforcing a provision is not a waiver.
• You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition or sale of the Services.
• Neither party is liable for delays caused by events beyond its reasonable control, such as internet, hosting or third-party outages.
