What it is
RPC is a production-grade analytics platform competing with LiveToken. It is read-only — no cart, no in-app buying, no trading or gifting; every deal links out to the marketplace that owns the listing. It surfaces mispriced listings, edition depth, pack expected value, and badge-weighted FMV across five Flow collections, with a Claude-powered AI concierge on every page.

- Tailwind 4 for styling
- Supabase (Postgres + Edge Functions + RLS)

Pipeline architecture
cron-job.org hits /api/pipeline-trigger?token=... every 20 minutes and runs sequentially:
- Ingest — pulls active listings from Top Shot GraphQL + Flowty
- Sales indexer — scans Flow blocks for
ListingCompleted + MomentPurchased events
- FMV recalc — weighted-average-price model with
days_since_sale and sales_count_30d
- FMV backfill — fills gaps from historical sales
- Listing cache — materialized snapshot for fast collection reads
