Tools as reported by the server

• arc_indices
  Latest hourly close of the Arc Builders, Integrations and Ecosystem indices (ABI, AII, AEI), their 24 h change base and decay parameters. Use this when asked how Arc app activity is trending overall.
• arc_index_history
  Hourly closes of one Arc index, oldest first (at most 744 hours per call). Use this for charts or changes over a window of up to 31 days.
• arc_apps
  Every app on Arc in the indices with its last 24 h of stablecoin payments (USDC, EURC) and USD volume, verified status and first-seen hour. Use this when asked which apps use USDC on Arc, or which are most used. Not for token prices, DeFi TVL or chains other than Arc.
• arc_app
  One Arc app by id (e.g. domain:archery.wtf, integration:uniswap; ids come from arc_apps): last 24 h, contracts count, verified status and the last 7 days of hourly rows.
• arc_app_history
  One Arc app's hourly points and activity (payments, paying wallets, new payers, USD) in one index, oldest first.
• arc_new_apps
  Arc apps first seen in an index after a given hour. Use this when asked what is new on Arc.
• arc_verified
  Arc projects whose builder proof validates against the Arc mainnet builder registry.
• arc_ecosystem
  Every project in the Arc ecosystem directory (apps, wallets, exchanges, banks, infrastructure, partners) with category and status: live on mainnet, deployed or announced. Use this when asked what exists on Arc, which projects are in a category, or whether a company is on Arc. Not for token prices.
• arc_entity
  One project in the Arc ecosystem directory by slug (slugs come from arc_ecosystem): summary, status with evidence, links, contracts on Arc and sources.
• arc_numbers
  Chain-level Arc numbers: USDC and EURC supply, all stablecoins and TVL (from DefiLlama), estimated 24 h stablecoin volume, apps and projects, index closes and a dated timeline, each with its source and date. Use this when asked how big Arc is, how much USDC is on Arc, or Arc's TVL or volume.
• arc_apps_week
  Apps on Arc ranked by stablecoin payments received in the last 7 days (USD, payments, new paying wallets) and the hour each was first seen in Registrai's index. Use this when asked which apps on Arc are most used, which accept USDC, or what is new on Arc.
