API & Indexer

Goal: serve market/order/position data to the web + agents, backed by an event indexer.

Status

packages/api exists but its build is broken (stale VerexClient import) — review item #1. Indexer not started (S5).

Design

• API (Fastify, S4): /markets, /orders, /positions/:user; Postgres (Markets / Orders / Fills / Positions); local docker-compose.
• Indexer (S5): stream OrderFilled / PositionsMerged / PayoutRedemption → Postgres; Pub/Sub local emulator; genesis backfill.

Open questions

• Pub/Sub vs Kafka for events (plan suggests Pub/Sub first).

Features

• Fix the API build (blocker)
  • Replace the v1 VerexClient import with the CTF client/stub
• REST API (S4)
  • /markets, /orders, /positions/:user (Fastify)
  • Postgres schema + docker-compose
• Indexer (S5)
  • Event stream → Postgres; Pub/Sub emulator; backfill
