Registrai Arc data
by cc.registrai
Server Details
Read-only data on Arc, Circle's blockchain, from Registrai: apps on Arc with their stablecoin payments (USDC, EURC), paying wallets and volume; the Arc ecosystem directory (258 projects with status, launch date and sources); Arc chain figures (USDC supply, TVL, daily transactions); and the hourly Arc indices. No key, CC BY 4.0. Website and method: https://builder.registrai.cc

A3.5/5.0
Scored across 13 tools
Disambiguation2/5
Six of the 13 tools concern Arc apps (arc_app, arc_apps, arc_apps_week, arc_apps_daily, arc_app_history, arc_new_apps), distinguished mainly by time window and aggregation, which is easy to misselect. Worse, arc_apps_week and arc_new_apps both instruct 'Use this when asked what is new on Arc', and arc_apps vs arc_apps_week both claim 'which apps are most used / accept USDC', creating direct trigger collisions.
Naming Consistency3/5
All names use a uniform snake_case arc_ prefix, which is good, but there is no verb and the suffix conventions are ad hoc: time windows mix 'week', 'daily', and 'history'. Singular vs plural (arc_app vs arc_apps) carries real semantic load and is a fragile distinction for an agent to rely on.
Tool Count4/5
13 tools is a reasonable scope for an analytics/lookup server and each tool maps to a plausible question. The app family is slightly over-fragmented into six near-variants that could be collapsed into fewer parameterized tools.
Completeness4/5
Coverage spans address labels, apps, ecosystem directory, indices and chain-level aggregates with history, which is a coherent lifecycle for a chain-data server. Minor gaps: no free-text search or lookup by name/contract to resolve into ids, and no historical series for the chain-level numbers beyond the index history.

Available Tools
13 toolsarc_address_labelArc address: labelARead-onlyIdempotentInspect
Who an address on Arc mainnet belongs to: the project or app, the address's role and the source of the label (directory entries, stablecoins, Registrai's chain scan, the contracts the Arc indices count per app). Use this when asked whose contract or address something is on Arc. No label usually means a wallet or an unnamed contract.
Inputs: address (required).
arc_appArc app: detailARead-onlyIdempotentInspect
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.
Inputs: id (required).
arc_app_historyArc app: hourly historyARead-onlyIdempotentInspect
One Arc app's hourly points and activity (payments, paying wallets, new payers, USD) in one index, oldest first.
Inputs: id (required), index (required), to, from.
arc_appsArc appsARead-onlyIdempotentInspect
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.
Inputs: sort.
arc_apps_dailyArc apps: daily USDCARead-onlyIdempotentInspect
USDC received per day by Arc apps and directory projects since mainnet's first day (2026-09-16), counted from every USDC transfer into their contracts, before any index rule (USD, transfers, distinct payers). One app (up to 31 days) or all apps (up to 7 days). Use this when asked how much USDC an app or exchange on Arc receives, or how a project's flows changed since launch.
Inputs: to, app, from.
arc_apps_weekArc apps, last 7 daysARead-onlyIdempotentInspect
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.
Inputs: no named parameters.
arc_ecosystemArc ecosystem: directoryARead-onlyIdempotentInspect
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.
Inputs: q, status, category.
arc_entityArc project: detailARead-onlyIdempotentInspect
One project in the Arc ecosystem directory by slug (slugs come from arc_ecosystem): summary, status with evidence, links, contracts on Arc and sources.
Inputs: slug (required).
arc_index_historyArc index: hourly historyARead-onlyIdempotentInspect
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.
Inputs: index (required), to, from.
arc_indicesArc indices: latestARead-onlyIdempotentInspect
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.
Inputs: no named parameters.
arc_new_appsArc apps: newly seenARead-onlyIdempotentInspect
Arc apps first seen in an index after a given hour. Use this when asked what is new on Arc.
Inputs: index (required), since (required).
arc_numbersArc in numbersARead-onlyIdempotentInspect
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.
Inputs: no named parameters.
arc_verifiedArc builders: verifiedBRead-onlyIdempotentInspect
Arc projects whose builder proof validates against the Arc mainnet builder registry.
Inputs: no named parameters.
