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 reports.

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|params|proposal|proposals]
icq sns neurons [cache|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.

Inspect local SNS neuron snapshots and their latest refresh-attempt metadata without making live calls:

icq sns neurons cache list
icq sns neurons cache status 1

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.

SNS governance nervous system parameters can be queried by list id or root principal:

icq sns params 1
icq sns params 23ten-uaaaa-aaaaq-aabia-cai --format json

SNS governance proposals can be queried as bounded live pages or direct detail lookups:

icq sns proposals 1 --limit 25
icq sns proposals 1 --status open
icq sns proposals 1 --before 100 --format json
icq sns proposal 1 387

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 the release gate, then bumps Cargo.toml and Cargo.lock for review. To finish a release in one Make target, use the Canic-style release targets:

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

Those targets bump, stage the release version files, create the release commit and annotated vX.Y.Z tag, then push with git push --follow-tags.

After the release commit and tag are pushed, publish the crate:

cargo publish --locked

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, sns params, sns proposal, sns proposals, and sns neurons are implemented for deployed mainnet SNS instances.
sns neurons refresh caches complete neuron snapshots for cache-backed sorting.
sns neurons cache list|status inspects local complete neuron snapshots and refresh-attempt metadata without live calls.
Additional IC query families can be added without coupling query code to deployment tooling.
