QXMP Oracle

QXMP Oracle Skill (RWA Proof-of-Reserve)

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

Safety

• Read-only API — no write operations available.
• Never fabricate asset valuations, proof timestamps, or freshness status.
• Always report isFresh honestly — a stale proof (isFresh: false) means data may be up to 1 day old.
• Parse valueUSD fields with parseFloat() — they are strings to preserve precision.
• Respect rate limits: exponential backoff on HTTP 429 using Retry-After header.
• Cache responses for 2–5 minutes; proofs are stable between daily updates.

Procedure

Report Asset Portfolio

1. Fetch: GET /assets?page=1&limit=100
2. Check success: true
3. Parse each valueUSD with parseFloat()
4. Flag ✅ Fresh or ⚠️ Stale per latestProof.isFresh
5. Report totals from data.summary.totalValue

Verify a Specific Asset

1. Fetch: GET /assets/{assetCode}
2. Report: name, type, jurisdiction, value, proof age, freshness
3. If isFresh: false, warn user proof is older than 24 hours

Rate Limit Handling

# Check for 429 and respect Retry-After
response=$(curl -sI "https://api.qxmp.ai/api/v1/rwa/assets")
if echo "$response" | grep -q "HTTP/.*429"; then
  retry=$(echo "$response" | grep -i "retry-after" | awk '{print $2}' | tr -d '\r')
  echo "Rate limited. Waiting ${retry}s..."
  sleep "$retry"
fi

Smart Contracts (On-Chain — Advanced)

For trustless verification without the REST API:

Asset codes: keccak256("QXMP:RHENO-JORC-ZA") — format QXMP:{PROJECT}-{STANDARD}-{COUNTRY}. Values stored at 8 decimal precision: valueUSD * 10^8.

Asset Types
