Include your builder key to see packs available exclusively to your integration. * **Access.** Omit `x-builder-api-key` for the public catalog. If you include a key, the call counts toward its rate limit. * **Display.** Use the pack and gacha machine video URLs to show a preview. Prices are strings in 18-decimal USDT units. * **Next request.** Use `slug` for [pack details](https://docs.renaiss.xyz/api-reference/gacha/get-pack.md) and `id` to [prepare a purchase](https://docs.renaiss.xyz/api-reference/gacha/prepare-pull.md). ## Request Optional builder key ## Response ## Error codes Match the HTTP status and response text to a row below.

Check the key. Do not retry with the same key. | | `403` | `API_AUTH_CREDENTIAL_NOT_ALLOWED` | `error` | `Credential is not allowed by this policy` Omit credentials, or send only an optional builder key in `x-builder-api-key`. | | `403` | `GACHA_V3_BUILDER_NOT_ACCEPTED_ON_PUBLIC_API` | `error` | `This builder checks out on its own surface, not on the public API` This builder key cannot be used on this API. Do not retry; contact Renaiss. | | `429` | `API_AUTH_RATE_LIMITED` | `error` | `Authentication rate limit exceeded` The builder key hit its rate limit.

Any active, approved builder key can prepare purchases. A collectible is an item a wallet can pull, trade, sell back or redeem, such as a card. This API calls every such item a collectible (e.g. cards), in paths, fields and descriptions. Browse publicly, then prepare and sign actions with the buyer wallet. Gacha history and buyback offers require your builder key; purchases and buybacks also require a wallet action signature. Private shipping data and redemption require a wallet access token, which the API issues from a registered partner origin after the wallet signs a sign-in message. Gacha and marketplace never use a wallet access token. Keep the builder key on your backend. The acting wallet is an EOA or a deployed ERC-1271 contract account. EIP-7702 delegated accounts, ERC-6492 and ERC-8010 wrapped signatures and Renaiss-managed Safes are refused (a Safe only after its signature verified). A pull to a contract account that cannot receive ERC-721 tokens returns `CONTRACT_WALLET_CANNOT_RECEIVE_NFT`. A failed chain read returns `API_AUTH_ERROR` (500). Wallet access tokens and redemption are EOA only. servers: - url: https://api.renaiss.xyz description: BNB Smart Chain - url: https://dev-api.renaiss.xyz description: BNB testnet security: [] tags: - name: Gacha v2 description: >- Direct-EOA pack browsing, purchases, collectible (e.g. card) reveals, purchase history and buybacks.
