Fetch real-world asset (RWA) data and proof-of-reserve status from the QXMP Oracle — managing $1.17 trillion in certified in-ground mining assets on the QELT...
The QXMP Oracle is a custom oracle infrastructure (not Chainlink or RedStone) providing cryptographically verified real-world asset data on the QELT blockchain. It manages 12 tokenized mining projects worth $1.17 trillion USD in certified in-ground mining assets — all on-chain.
API Base URL: https://api.qxmp.ai/api/v1/rwa
Auth: None required — fully public API
CORS: Enabled — works from any browser
Update frequency: Oracle proofs update ~once per 24 hours
isFresh honestly — a stale proof (isFresh: false) means data may be up to 1 day old.valueUSD fields with parseFloat() — they are strings to preserve precision.HTTP 429 using Retry-After header.curl -fsSL "https://api.qxmp.ai/api/v1/rwa/health"
curl -fsSL "https://api.qxmp.ai/api/v1/rwa/assets?page=1&limit=100"
Key fields per asset:
| Field | Type | Notes |
|---|---|---|
assetCode | string | e.g. "QXMP:RHENO-JORC-ZA" |
name | string | Human-readable project name |
type | string | Gold, Diamond, Rare Earth Elements, etc. |
jurisdiction | string | ZA, NA, MZ, LR, AU |
valueUSD | string | Parse with parseFloat() |
latestProof.isFresh | boolean | true if proof < 24h old |
latestProof.ageHours | string | Hours since last proof |
latestProof.timestamp | string | ISO 8601 |
curl -fsSL "https://api.qxmp.ai/api/v1/rwa/assets/QXMP:RHENO-JORC-ZA"
Returns full asset details including onChain data and proofHistory[].
curl -fsSL "https://api.qxmp.ai/api/v1/rwa/stats"
Returns totalAssets, totalValue, averageValue, byType[], byJurisdiction[].
