Read `status` and `detail` in the HTTP `200` response to see whether it needs a correction. Read the outcome before [requesting a courier quote](https://docs.renaiss.xyz/api-reference/redeem/quote-shipping.md). A successful HTTP request can still report an address problem. * `verified` means the address passed validation. * For `corrected`, `missing_information`, `review_required`, `failed` or `none`, read `detail` to decide what to show the user. ## Request Builder key and wallet access token ## Response ## Error codes Match the HTTP status and response text to a row below. For guidance on codes shared across endpoints, see [Error meanings and recovery](https://docs.renaiss.xyz/api-reference/errors.md). | HTTP | Error code | Text field | Response text and recovery | | :- | :- | :- | :- | | `400` | `REDEEM_ADDRESS_VALIDATION_API_ERROR` | `error` | `Redemption request failed` The address check did not give an answer. Try again later. | | `400` | `WRONG_REQUEST_PARAMS` | `error` | `Shipping destination is not supported` `Invalid redemption input` `Request body is too large` A field is missing or has the wrong form, the country is not supported for shipping, or the country needs a state and none was sent. Fix the address and send it again. | | `401` | `API_AUTH_INVALID_CREDENTIAL` | `error` | `Invalid authentication credential` The builder key or the wallet access token is malformed, unknown, expired or revoked. Check the key. For the token, refresh the tokens or have the wallet sign in again. | | `401` | `API_AUTH_MISSING_CREDENTIAL` | `error` | `Required authentication credential is missing` The builder key or the wallet access token is missing. Send both: the key in the `x-builder-api-key` header and the token as a Bearer token. | | `403` | `API_AUTH_CREDENTIAL_NOT_ALLOWED` | `error` | `Credential is not allowed by this policy` A credential this route does not take was sent. Send the builder key and the wallet access token only. | | `403` | `API_AUTH_INSUFFICIENT_SCOPE` | `error` | `Required authentication scope is missing` The wallet access token lacks the scope this route needs: `redeem:read` to read, `redeem:write` to change. Have the wallet sign in again and ask for the scope. | | `403` | `API_AUTH_INTEGRATION_MISMATCH` | `error` | `Authentication integrations do not match` The wallet access token was issued to another builder than the key. Use the key of the builder that issued the token. | | `403` | `API_AUTH_SUBJECT_MISMATCH` | `error` | `Authentication subjects do not match` The wallet access token is not for the chain of this API. Have the wallet sign in again for the right chain. | | `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. Wait a little, then retry at a lower rate. | | `500` | `API_AUTH_INVALID_CONFIGURATION` | `error` | `Internal server error` Contact Renaiss with `x-request-id` if wallet authentication keeps failing. | | `500` | `API_AUTH_ERROR` | `error` | `Internal server error` | | `500` | `FUNCTION_ERROR` | `error` | `Internal server error` | | `500` | `REDEEM_ADDRESS_VALIDATION_FAILED` | `error` | `Internal server error` Read again after a short wait. | ## OpenAPI ````yaml api-reference/openapi.json POST /v2/redeem/address/validate openapi: 3.1.1 info: version: 1.0.0 title: Renaiss Builder API v2 description: >- Builder API v2 for gacha, marketplace and redemption with external wallets on BNB Smart Chain (chain 56). 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.
