Successful response
FieldTypeDescription
items
object[]
Per-issuance metadata-only records. Unmatched IDs are silently omitted.
items[].id
string
MPTokenIssuance ID (same as `issuance_id`). Top-level alias for shape parity with token / NFT detail.
items[].issuance_id
string
On-chain MPTokenIssuance ID (hex string).
items[].issuer
string
XRPL classic address of the issuer.
items[].created_at_ledger
integer
Ledger sequence where the issuance was created.
items[].destroyed_at_ledger
object
Ledger sequence where the issuance was destroyed; `null` while active.
items[].burned
boolean
True once `destroyed_at_ledger` is set.
items[].metadata
object
items[].metadata.token
object
items[].metadata.token.name
object
Display name of the MPT asset (XLS-89 `n`).
items[].metadata.token.ticker
object
Uppercase ticker symbol — ≤6 chars, A-Z 0-9 (XLS-89 `t`). `null` when the metadata didn't declare one.
items[].metadata.token.desc
object
Asset purpose / description (XLS-89 `d`).
items[].metadata.token.icon
object
URL to the asset logo (XLS-89 `i`). HTTPS or `ipfs://…`.
items[].metadata.token.asset_class
object
XLS-89 `ac`: top-level asset classification (`rwa` / `memes` / `wrapped` / `gaming` / `defi` / `other`).
items[].metadata.token.asset_subclass
object
XLS-89 `as`: narrower sub-category. Required by the spec when `asset_class = "rwa"`; free-text otherwise.
items[].metadata.token.issuer_name
object
Issuer display name as declared in the metadata (XLS-89 `in`).
items[].metadata.token.urls
object[]
Categorized external links published by the issuer (XLS-89 `us`). Empty array when none declared.
items[].metadata.token.additional_info
object
Free-form supplementary metadata (XLS-89 `ai`) — typically rate / term / settlement details for RWAs. Schema is issuer-defined.
items[].metadata.token.metadata_uri
object
Raw on-chain MPTokenMetadata field — hex-encoded VL bytes exactly as the ledger emits them. Hex-decodes to either a URL (`ipfs://…`, `https://…`, `ar://…`) or an inline JSON literal (`{…}`) when the metadata fits inside the on-chain field. The ledger value is preserved verbatim so callers can verify on-chain bytes against the live ledger; the decoded form is served via the resolver-mirrored copy on `metadata_url` when the URI was external.
items[].metadata.token.metadata_url
object
CDN URL of the mirrored metadata.json. Populated when the resolver hex-decodes `metadata_uri` to an external URL (http/https/ipfs/ar), fetches the bytes, and uploads them to `assets/mpt/<issuance_id>/metadata.json`. `null` when the on-chain URI was inline JSON (nothing to mirror) or when the resolver has not processed this row yet.
items[].metadata.issuer
object
items[].metadata.issuer.address
string
XRPL classic address of the issuer.
items[].metadata.issuer.name
object
Issuer display name from `account_metadata` / TOML / curator.
items[].metadata.issuer.domain
object
Verified domain associated with the issuer account.
items[].metadata.issuer.kyc
object
True when the issuer has completed third-party KYC.
