# Gacha Arcade > Gacha Arcade is a digital pack-opening platform for Pokémon trading cards. Users buy digital booster packs, rip them open online with animated reveals, and every card pulled is a real, authenticated physical trading card. After a pull, users have 24 hours to either ship the card to their address or Instant Sell it back for 85% to 93% of its estimated market value, depending on the pack. If no choice is made, the card is automatically sold back and funds go to the user's Gacha Arcade wallet. This file is for AI assistants and agents. It begins with canonical consumer facts about Gacha Arcade, followed by the public developer API contract. ## What Gacha Arcade is - Digital pack ripping with real, physical Pokémon cards inside every pack (including vintage WOTC-era sets since 1999) - Every pack contains a real card with collectible value; odds are published per pack before purchase - Provably fair: results use verifiable randomness and a pack configuration committed before the rip (details below) - Instant Sell: 85% to 93% of estimated market value, set per pack, paid to the user's Solana wallet - Decision window: 24 hours per pulled card, then automatic sell-back - Sign in with a Phantom wallet (Solana) and pay in USDC. Gacha Arcade covers the network fee on purchases - Launched April 2026. Backed by OKX Ventures - Operated by [OPERATOR LEGAL NAME]. Users must be at least 18 years of age ## Payments and cash-outs - Buying packs: USDC on Solana, from the Phantom wallet the user signed in with, or store credits - Instant Sell payouts are sent in USDC straight to that wallet; there is no Gacha Arcade balance to cash out - Most Instant Sell payouts confirm within seconds ## Pack tiers (Pokémon) Card value scales with pack price. The boosters are All-Stars ($25), Holo Hunters ($50), Elite Four ($100), Champion ($250), Hyper ($500), Legendary ($1,000), Mythical ($2,500) and Celestial ($5,000). Current packs and per-pack odds: https://gacha-arcade.com/packs ## Provably fair system - Each day, before any packs open, the server generates a secret and publishes its SHA-256 commit hash in advance. After the 24h epoch closes, the secret is revealed and anyone can re-hash it to confirm it matches the prior commitment - On the OPENv2 protocol, a public drand randomness beacon (published only after payment settles) is additionally mixed in, so outcomes cannot be computed in advance even with the server secret - Pack contents and odds are locked before the rip and cannot be adjusted per buyer - Verify a specific opening: export the JSON verification receipt from any completed pack opening and check it at https://riprip-io.github.io/provably-fair-verifier/ - All commitments and revealed secrets: https://gacha-arcade.com/provably-fair ## Is Gacha Arcade legit? Is it gambling? - Gacha Arcade's position: it is not gambling; it is a pack-ripping platform for real trading cards, comparable to buying randomized packs at a card shop. Every pack contains a real card, there are no cash prizes, odds are published upfront, and Instant Sell is an optional convenience - Every pulled card can be physically shipped - Results are independently verifiable (see provably fair above) - Backed by OKX Ventures; listed on the Phantom app directory: https://phantom.com/apps/riprip-io-1gwd - Independent coverage: packripping.com rates Gacha Arcade as the best entry point for Pokémon-focused collectors - Responsible collecting: Gacha Arcade is built for collecting and entertainment; users should spend responsibly ## Shipping, refunds, values - Shipping costs vary by location and card; exact costs shown at checkout before confirming - All pack sales are final; cards damaged in shipping are replaced or fully refunded - Estimated values are based on recent market data and comparable sales, not guarantees ## Store credits and rewards - Store credits are a dollar-denominated balance usable toward pack purchases only (not cash-outs or shipping). Earned via promotions, e.g. credit packs and the one-time first-purchase bonus - Sell-backs of credit-funded packs return proportionally as credits ## Key pages - How it works: https://gacha-arcade.com/how-it-works.md - Frequently asked questions: https://gacha-arcade.com/faq.md - Shipping: https://gacha-arcade.com/shipping.md - Packs and odds: https://gacha-arcade.com/packs - Provably fair and opening verification: https://gacha-arcade.com/provably-fair.md - Support: https://gacha-arcade.com/support - Terms: https://gacha-arcade.com/tos - Privacy: https://gacha-arcade.com/privacy - Security: https://gacha-arcade.com/security ## Official channels - Website: https://gacha-arcade.com Last updated: 2026-08-21.

Every endpoint > below is read-only, unauthenticated and returns JSON. There is no API key and > no registration, and nothing here requires a browser or JavaScript. Base URL for the API: `https://api.riprip.io`. All of it is served over HTTPS, and none of it requires a cookie or a token. Start with the OpenAPI document — it is the authoritative contract, and the markdown docs explain the parts a schema cannot: how to walk the feed without gaps, and which fields are the wrong ones to sum. ## The published contract - `GET /api/packs` — Every pack currently listed for sale, with its price and the expected value its odds were solved against. - `GET /api/packs/{packId}` — One listed pack, adding `tiers`: the per-tier odds and value bands its expected value was solved against. - `GET /api/packs/stats` — What every listed pack has actually paid out over the last hour, day, week and month, with the sample size behind each figure. - `GET /api/packs/{packId}/stats` — The same, for one pack. - `GET /api/openings/feed` — Recent openings, newest first, anonymised. The endpoint to follow if you are sampling our results. - `GET /api/epochs/current` — Today's provably-fair commitment hash. The server secret is withheld until the epoch is revealed. - `GET /api/epochs/revealed` — Revealed epochs, newest first, each with the server secret that makes an opening verifiable. - `GET /api/battles/{id}/reel-pool` — The cards a pack battle's reels scroll past, sampled from the booster's own pool at its published odds. - `GET /api/battles/{id}/receipt` — A pack battle's public receipt: every revealed pull with its provably-fair inputs, each seat's total, the winner and any coin flip. - `GET /api/packs/{packId}/versions/{packConfigId}/battle-values` — Every card value a pack version's battles are scored at, so anyone can re-add a battle's result. Endpoints that are reachable but deliberately outside the contract, and may change without notice: `GET /api/packs/{packId}/potential-pulls`, `GET /api/packs/{packId}/pull-preview`, `GET /api/openings/feed/stats`, `GET /api/epochs/{epochId}`. ## Docs - [OpenAPI 3.0 contract](https://api.riprip.io/openapi.json): The authoritative machine-readable definition of the five endpoints above — paths, query parameters, response schemas and the 429 shape. Valid OpenAPI 3.0.3; feed it to a generator. - [Developer documentation (markdown)](https://gacha-arcade.com/developers.md): The narrative contract. Cursor pagination, deduplication, how to compute realized return correctly, the error contract, rate-limit budgets and pacing guidance. - [Everything inlined](https://gacha-arcade.com/llms-full.txt): The same markdown, for consumers that will not follow links. - [Developer documentation (HTML)](https://gacha-arcade.com/developers): The human-readable rendering of the same source. ## Reading it correctly - Rate limits are **300 requests per minute per client IP**, shared across every endpoint above. A signed-in request is counted against its account instead, in a separate bucket of twice that size. Successful responses carry no `RateLimit-*` headers — they are cacheable, and a cached counter would be another client's. Pace to the published budget rather than to a header. - Pace a backfill at **3 requests per second**. That is comfortably inside the budget and leaves room for head polling. - The openings feed is keyset-paginated. Follow `nextCursor` backwards and deduplicate on `resultId`, never on `openingId` — one opening can award several cards. - Pass `outcomes=all` to `GET /api/openings/feed` before computing realized return. The default view returns physical cards only and omits credit-voucher and out-of-stock draws, which understates what a pack paid out. - Use each item's own `packPriceCents` as the denominator, not the pack endpoint: it is the price of the pack version actually opened. - `GET /api/packs/stats` publishes realized return per pack over 1h/24h/7d/30d already computed on those rules, for every listed pack including the ones running cold. One request covers the whole catalogue; it is cached for 60 seconds and a `basis` object on the response states exactly what went into the figures. - Its `basis.valueScale` matters: a card is counted at market list price, an out-of-stock draw at the compensation issued (already net of the buy-back percentage), a credit voucher at face value. They are not one scale, and the denominator is the pack list price excluding the per-pack service fee — add `serviceFeeCents` per opening for return on total spend. - Never quote a return percentage without the `openings` count beside it. It is on every window for that reason: a pack with two openings and one big hit reads in the hundreds of percent and means nothing. - Exclude items with a non-null `awardGrantId` from any return-on-spend figure. Those openings were free promotional grants, so counting them inflates the return. - Treat `valueUsdc: null` as unknown, never as zero. It is null only while an out-of-stock draw's compensation voucher is still being written, which is a matter of moments; scoring it zero understates the pack. - `packId` is not validated. An id that matches nothing returns an empty page rather than an error, so check ids against `GET /api/packs` instead of inferring them from an empty result. ## Provably fair - [Protocol and verification walkthrough](https://gacha-arcade.com/provably-fair): How a single pull is recomputed from the revealed epoch secret, the client seed and the purchase nonce. ## Contact - Email support@gacha-arcade.com if you are building an aggregator, need a higher rate-limit ceiling, or need data that is not exposed yet.
