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|neurons]
icq sns proposals [cache|refresh]
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 and require an explicit refresh first:

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 cached list views or direct live detail lookups. Normal proposal list views auto-create a complete local snapshot on first use, then apply supported view options locally. Proposal detail lookups reuse an existing complete local snapshot when it contains the requested proposal, then fall back to live detail lookup. Topic filters and adopted/rejected status filters currently use bounded live queries:

icq sns proposals 1 --limit 25
icq sns proposals 1 --status open
icq sns proposals 1 --status decided
icq sns proposals 1 --sort created
icq sns proposals 1 --sort decided
icq sns proposals 1 --sort executed
icq sns proposals 1 --sort failed
icq sns proposals 1 --sort created --asc
icq sns proposals 1 --topic governance
icq sns proposals 1 --before 100 --format json
icq sns proposal 1 387
icq sns proposal 1 387 --ballots

Proposal list views support --sort api|id|created|decided|executed|failed. Local sort modes accept --asc or --desc, defaulting to descending. Cache-compatible views filter and sort complete local snapshots before applying --limit; bounded live fallback views sort the returned API rows.

Complete SNS proposal snapshots can also be refreshed and inspected manually:

icq sns proposals refresh 1
icq sns proposals cache list
icq sns proposals cache status 1

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 proposals auto-creates and reuses complete proposal snapshots for cache-compatible list views.
• sns proposals refresh force-refreshes complete proposal snapshots.
• sns proposals cache list|status inspects local complete proposal snapshots and refresh-attempt metadata without live calls.
• 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.
