Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00131 | $0.01923 |
| Opus 5.5 | $0.00052 | $0.00769 |
| Sonnet 5.5 | $0.00026 | $0.00385 |
| Haiku 4.5 | $0.00013 | $0.00192 |
Grade A, and why
api-monitoring scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
API Monitoring
Overview
A Monitor is a recurring, scheduled check against a live API. The CLI now
owns its full lifecycle: monitor create/update/delete/pause/resume
manage the schedule and configuration, monitor list/get discover and
inspect existing ones, monitor run triggers an ad hoc run, and monitor jobs/monitor runs inspect what actually happened during a run. There is
no remaining task here that has to go through the Postman app.
postman runner is a separate, infrastructure-level concern: it starts a
self-hosted execution agent so Monitor runs can reach APIs that live behind
a private network Postman's cloud can't reach directly, and it lists the
values (Postman regions or self-hosted runner ids) that monitor create/update --runner accepts.
Creating and scheduling a monitor
monitor create -c <collectionId> is the minimum — name defaults to the
linked collection's own name. Workspace comes from -w, or falls back to
the workspace named in the local .postman/resources.yaml manifest;
without either, creation fails. --schedule <cron> plus --timezone
(defaults to the host machine's zone) set when it fires; --runner
(repeatable) says where from — a Postman region name (postman runner regions) or a self-hosted runner's id (postman runner list), and both
can be mixed in the same monitor. --notify-email (repeatable) and
--notification-limit control failure alerts. The run itself is shaped by
the same options as a collection run — --retry (service caps at 2),
--timeout, --delay, --strict-ssl/--insecure,
--follow-redirects/--block-redirects, and dataset iteration via
--dataset-id/--dataset-view-id/--iteration-count/
--iteration-strategy. Creation triggers an immediate run by default; pass
--no-run-now to skip that.
Updating, pausing, and deleting
monitor update <monitorId> takes the same schedule/runner/notification/
run-option flags as create, plus --clear-notifications to wipe every
recipient. It cannot change the linked collection or environment — delete
and recreate the monitor instead — and it does not pause or resume; use
monitor pause/monitor resume for that. monitor delete <monitorId>
prompts for confirmation unless -y/--yes is passed, and is permanent.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

api-monitoring is a skill published in the GitHub repository Postman-Devrel/postman-claude-code-plugin (41 stars, last pushed 21d ago), licensed Apache-2.0. It adds 131 tokens to every session and 1,923 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-20.
