ic-query

ic-query provides the icq executable for read-only Internet Computer metadata queries.

icq currently supports NNS and SNS metadata queries: registry version, subnet catalog lookup, node/provider/operator/data-center inventory, topology reports, and deployed SNS listings.

Install

From this checkout:

make install

From crates.io after publication:

cargo install ic-query

Commands

icq nns help
icq nns registry version
icq nns subnet [list|info|refresh]
icq nns node [list|info|refresh]
icq nns node-provider [list|info|refresh]
icq nns node-operator [list|info|refresh]
icq nns data-center [list|info|refresh]
icq nns topology [summary|coverage|versions|health|gaps|capacity|regions|providers|refresh]
icq sns [list|info|token]
icq sns neurons [refresh]

Use icq nns <family> help, icq nns topology <report> help, or icq sns <command> help for command options.

Most commands support text output by default and JSON output with --format json:

icq --network ic nns subnet info ryjl3-tyaaa-aaaaa-aaaba-cai --format json

Cache

The NNS subnet, node, provider, operator, data-center, and topology commands use project-local cache files under .icq/. Refresh commands fetch current mainnet registry data and replace the matching cache atomically:

icq nns subnet refresh
icq nns topology refresh

List/info commands populate their component cache on first use and print the API endpoint they are calling before creating it. Refresh commands force a fresh fetch and replace the matching cache.

SNS neuron commands keep quick --sort api output on a bounded live query. Whole-collection neuron sorts use complete snapshots:

icq sns neurons refresh 1
icq sns neurons 1 --limit 500 --sort stake

Complete SNS neuron snapshots live under .icq/sns/ic/<root-principal>/neurons/full.json. Failed or capped refresh attempts are recorded separately and do not replace the last complete snapshot. Refresh shows a same-line stderr progress counter with pages and rows fetched when running in a terminal.

Live API neuron listings are capped at 100 rows per call. Cache-backed sorts can use larger --limit values because they read from the complete local snapshot.

Neuron IDs are shortened to eight characters in text tables by default. Use icq sns neurons 1 --verbose to show full neuron IDs. Text output shows current SNS token amounts, including token fee, total supply, stake, maturity, and staked maturity, as token decimals with two places. JSON keeps the raw base-unit and e8s fields.

Development

This repository pins the local toolchain to Rust 1.96.0 while declaring Rust 1.91.0 as the crate MSRV.

make fmt-check
make clippy
make test
make package

The combined local gate is:

make ci

Release version bumps are available after the release contents are committed and the worktree is clean:

make patch
make minor
make major

Each target runs make test, bumps Cargo.toml and Cargo.lock, validates the package, commits the release version, and creates an annotated vX.Y.Z tag. Use the Canic-style release targets to push the release commit and tag after the same gate succeeds:

make release-patch
make release-minor
make release-major

Integration

icq is a standalone metadata lookup tool. Orchestration, deployment, and application repositories can call the CLI when they need IC metadata instead of linking registry adapters directly. For one integration example, see Canic.

Status

The command namespace is intentionally small:

nns is implemented.
sns list, sns info, sns token, and sns neurons are implemented for deployed mainnet SNS instances.
sns neurons refresh caches complete neuron snapshots for cache-backed sorting.
Additional IC query families can be added without coupling query code to deployment tooling.
