Postman Explore — Printing Press CLI
Prerequisites: Install the CLI
This skill drives the
binary.
You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:
- Install via the Printing Press installer:
bash
npx -y @mvanhorn/printing-press install postman-explore --cli-only
- Verify:
postman-explore-pp-cli --version
- Ensure (or ) is on .
If the
install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.23+):
bash
go install github.com/mvanhorn/printing-press-library/library/developer-tools/postman-explore/cmd/postman-explore-pp-cli@latest
If
reports "command not found" after install, the install step did not put the binary on
. Do not proceed with skill commands until verification succeeds.
When to Use This CLI
Pick this CLI when you need to programmatically discover, compare, or watch community-contributed Postman Collections / workspaces / APIs / flows. Ideal for AI agents asked to find a canonical Postman Collection for a vendor, for API curators comparing publishers in a category, and for monitoring scripts that watch network changes. Skip this CLI for managing your own private Postman workspace — that's the authenticated Postman product API, which is a different surface entirely.
Unique Capabilities
These capabilities aren't available in any other tool for this API.
Discovery that compounds locally
-
— One command finds the best community Postman Collection for a vendor, ranked by publisher verification, fork count, and recency.
When the user asks an agent for a vendor's Postman Collection, this returns the best canonical choice in one call instead of forcing the agent to dedupe a search result list.
bash
postman-explore-pp-cli canonical stripe --json
-
— Rank entities by any metric (weekForks, monthViewCount, etc.) with category and entity-type narrowing.
When agents need to recommend the most-forked collections THIS week, not the all-time leaders, this is the only path that works.
bash
postman-explore-pp-cli top --metric weekForkCount --type collection --category payments --limit 10
-
— Given an entity numeric id, return collections with overlapping name, summary, and category — ranked by FTS relevance score against the seed entity's text.
When an integrator finds one collection but wants to compare against alternatives, this returns the rivals in one call rather than forcing a fresh search.
bash
postman-explore-pp-cli similar 10289 --limit 5 --json
Comparative analysis
-
— Aggregate fork counts across every entity per publisher within a category; rank teams by total community gravity.
API curators picking between vendors need cross-publisher comparison. Agents recommending an integration partner need this to break ties.
bash
postman-explore-pp-cli publishers top --category developer-productivity --limit 5 --json
-
— For a category slug, return: total entity counts per type, top 5 publishers by aggregate fork count, and top 5 entities by viewCount. One command, one structured payload.
API curators evaluating a vertical (payments, AI, devops) want one snapshot of who dominates and what's popular; this is exactly that snapshot.
bash
postman-explore-pp-cli category landscape payments --json
Time-windowed signals
-
— Compare two synced snapshots and report new entities, removed entities, and entities whose updatedAt advanced.
Agents tracking when a vendor publishes a new collection or updates an existing one rely on this; there is no other way to know.
bash
postman-explore-pp-cli drift --since 7d --type collection --json
-
— Rank collections by acceleration ratio: (weekForkCount × 4) / monthForkCount. Surfaces collections breaking out before they top the popular list.
Catching a breakout collection before it tops the popular sort is high-value for API curators tracking emerging vendors.
bash
postman-explore-pp-cli velocity --type collection --top 10
Quality signals
-
— When passed --verified-only, the browse command filters to entities owned by publishers with the verified-team flag set.
When you want only the official-vendor collections (not community forks), this is the cleanest filter.
bash
postman-explore-pp-cli browse collection --verified-only --category payments --json --limit 5
HTTP Transport
This CLI uses Chrome-compatible HTTP transport for browser-facing endpoints. It does not require a resident browser process for normal API calls.
Discovery Signals
This CLI was generated with browser-observed traffic context.

Finding the right command
When you know what you want to do but not which command does it, ask the CLI directly:
bash
postman-explore-pp-cli which "<capability in your own words>"
resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code
means at least one match; exit code
means no confident match — fall back to
or use a narrower query.
Recipes
Find Stripe's official collection
bash
postman-explore-pp-cli canonical stripe --json --select id,name,publisher.publicHandle,metrics.forkCount
The canonical command picks the verified-publisher, highest-fork-count match and narrows the JSON to the four fields agents actually need.
Compare top payments publishers
bash
postman-explore-pp-cli publishers top --category payments --limit 5 --json
Aggregate fork counts across each publisher's full portfolio in the payments category.
What changed on the network this week
bash
postman-explore-pp-cli sync && postman-explore-pp-cli drift --since 7d --type collection --json
Sync, then diff against the previous snapshot to find newly added or recently updated collections.
Browse top developer-productivity collections, narrow to verified publishers
bash
postman-explore-pp-cli browse collection --category 4 --verified-only --limit 10 --json --select name,publisher.publicHandle,metrics.viewCount,redirectURL
Use --select with dotted paths to avoid pulling the full ~5 KB metric array per record — keeps output small for agent context.
Find accelerating collections in payments
bash
postman-explore-pp-cli velocity --type collection --category payments --top 10
Velocity ranks by week-vs-month fork rate, surfacing collections that are breaking out before they top the all-time popular list.
Find collections similar to a seed
bash
postman-explore-pp-cli similar 10289 --limit 5 --json
More-like-this query against the local FTS index — useful for discovering rival or complementary community collections.
Get a category-wide snapshot
bash
postman-explore-pp-cli category landscape payments --json
Combines per-type counts, top publishers, and top entities for a category in one structured payload.
Auth Setup
No authentication required.
Run
postman-explore-pp-cli doctor
to verify setup.
Agent Mode
Add
to any command. Expands to:
--json --compact --no-input --no-color --yes
.
-
Pipeable — JSON on stdout, errors on stderr
-
Filterable —
keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:
bash
postman-explore-pp-cli category get mock-value --agent --select id,name,status
-
Previewable —
shows the request without sending
-
Offline-friendly — sync/search commands can use the local SQLite store when available
-
Non-interactive — never prompts, every input is a flag
Response envelope
Commands that read from the local store or the API wrap output in a provenance envelope:
json
{
"meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
"results": <data>
}
Parse
for data and
to know whether it's live or local. A human-readable
summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.
Agent Feedback
When you (or the agent) notice something off about this CLI, record it:
postman-explore-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
postman-explore-pp-cli feedback --stdin < notes.txt
postman-explore-pp-cli feedback list --json --limit 10
Entries are stored locally at
~/.postman-explore-pp-cli/feedback.jsonl
. They are never POSTed unless
POSTMAN_EXPLORE_FEEDBACK_ENDPOINT
is set AND either
is passed or
POSTMAN_EXPLORE_FEEDBACK_AUTO_SEND=true
. Default behavior is local-only.
Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.
Output Delivery
Every command accepts
. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:
| Sink | Effect |
|---|
| Default; write to stdout only |
| Atomically write output to (tmp + rename) |
| POST the output body to the URL ( or when ) |
Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.
Named Profiles
A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.
postman-explore-pp-cli profile save briefing --json
postman-explore-pp-cli --profile briefing category get mock-value
postman-explore-pp-cli profile list --json
postman-explore-pp-cli profile show briefing
postman-explore-pp-cli profile delete briefing --yes
Explicit flags always win over profile values; profile values win over defaults.
lists all available profiles under
so introspecting agents discover them at runtime.
