Changelog

v1.3.0 (Unreleased)​

Rate verification system

All rates returned by /v1/rates/live now include status, confidence, and flags fields. Exchange VWAP is verified against a synthetic cross-rate benchmark computed as CRYPTO/USDT * USD/FIAT.

  • New verification statuses: verified, caution, unverified. See Verification.
  • New optional parameters: include_synthetic (all tiers), include_sources (Builder+), include_audit (Enterprise).
  • Hourly FX rate collection (USD/NGN, USD/ZAR, USD/KES, USD/GHS, USD/UGX) for synthetic price computation.
  • Internal USDT pairs (BTCUSDT, ETHUSDT, XRPUSDT, SOLUSDT) added for synthetic calculation -- not exposed to API customers.
  • Default page limit for historical endpoint reduced from 1000 to 500.
  • GET /v1/premium endpoint for exchange VWAP vs synthetic cross-rate premium analysis (Builder+).
  • GET /v1/indices endpoint for MXNCI (Nigerian Crypto Index) and ACLI (African Crypto Liquidity Index) composites (Builder+).
  • GET /v1/certificates/{pair}/{timestamp} endpoint for HMAC-SHA256 signed rate attestation certificates (Enterprise).
  • Audit trail system with HMAC-SHA256 signed records for every rate computation.
  • Tier feature gating: confidence_scores, synthetic_breakdown, source_transparency, audit_trail flags enforced per tier via settings.yaml.
  • make backfill-price-verification script for backfilling historical verification data.
  • make backfill-audit-trail script for backfilling audit trail records.
  • API key info cached in Redis with 60-second TTL for faster authentication.
  • query_latest_verification optimised with 2-hour time filter (920ms to sub-1ms).
  • Added Ovex, Busha, and AltCoinTrader as exchange sources (30 new pair mappings across 3 exchanges).
  • Dead market detection: ticker-only exchanges with empty order books or extreme bid-ask spreads are automatically skipped.
  • Removed SOLUGX and USDTETB pairs (no viable exchange source).
