At a glance

OpenRouter real spend — key limit and usage today/week/month, one request's billed cost by generation id, account credits.

  • Asked what OpenRouter charged
  • Calls node; needs OPENROUTER_API_KEY and OPENROUTER_MANAGEMENT_KEY
  • Whether a key is near its limit

What it does

Cost Openrouter is an agent skill from ruvnet/ruflo. OpenRouter real spend — key limit and usage today/week/month, one request's billed cost by generation id, account credits. Use when asked what OpenRouter charged or whether a key is near its limit. Network and API key: asks first.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Model routing and gateways. It works with OpenRouter. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.

When your agent uses it

  • Asked what OpenRouter charged
  • Whether a key is near its limit

Example prompts

  • “/cost-openrouter”

Requirements

  • A credential in OPENROUTER_API_KEY
  • A credential in OPENROUTER_MANAGEMENT_KEY
  • Pre-approved tools (allowed-tools): Bash

What it can do on your machine

Read from SKILL.md and the folder at commit 58e0ae7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENROUTER_API_KEY
    • OPENROUTER_MANAGEMENT_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cost Openrouter loads about 336 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 112 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~336

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cost OpenRouter

Network skill. Ask the user before running it, and run it only with their yes.

bash
node ${CLAUDE_PLUGIN_ROOT}/scripts/openrouter.mjs key --yes
node ${CLAUDE_PLUGIN_ROOT}/scripts/openrouter.mjs generation gen-abc123 --yes
node ${CLAUDE_PLUGIN_ROOT}/scripts/openrouter.mjs credits --yes

Rules

  • Without --yes the script prints the call it would make and sends nothing.
  • The key comes from OPENROUTER_API_KEY (credits: OPENROUTER_MANAGEMENT_KEY). Never ask the user to paste a key, never print, log or write one.
  • OpenRouter's usage.cost / total_cost is authoritative; do not recompute it from list prices.
  • credits needs a management key (a normal key returns 403). A fresh generation can 404 briefly: retry.
  • BYOK rows carry the 5% OpenRouter fee in usage, the provider's charge in upstream_inference_cost: show both, labelled.
  • Fallback and openrouter/auto can change the billed model: report model and provider_name as returned.
