Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

agentcard 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 9d 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.

Agentcard: cards you can pay with

Agentcard gives you a real payment method without ever holding the user's own card. The user funds a wallet; you mint a virtual debit card sized to one purchase, pay, and the card closes itself after the first approved charge. Subscriptions use multi-use cards with a hard total limit. Every money move needs the user's explicit go-ahead.

VOCABULARY: the user's WALLET is their cards; their BALANCE is their cash. Cards are funded from the balance.

Setup (once per computer)

Install the CLI on your computer; it stays installed:

npm install -g agent-cards   # or: npx -y agent-cards@latest <command>
agent-cards whoami           # signed in? shows the account. Otherwise: sign in below

Sign in (once per person)

Each person connects their own Agentcard account. Never sign one person's agent into another person's account.

  1. agent-cards login --email <their email> sends a one-time code to that email.
  2. Ask them to read the code back to you in chat (if they have connected their inbox to you and ask you to, you may fetch it yourself).
  3. agent-cards login --email <their email> --code <code> completes sign-in. The session persists in your $HOME across turns.

Headless alternative: if $AGENT_CARDS_JWT is set in your environment (for example vended through the keychain), the CLI uses it directly; no login needed. New users can create an account at https://agentcard.sh, or login walks them through it by email.

Driving it

The CLI is an agent-first tool catalog (the same catalog as the Agentcard MCP server). Load the canonical guide into context once per session, then follow it:

agent-cards api --agent-help          # read this fully, once per session
agent-cards api search <regex>        # find tools (balance, create_card, buy, ...)
agent-cards api describe <tool>       # schema before first use; never guess
agent-cards api call <tool> '<json>'  # invoke; JSON result on stdout

Tools that move money refuse to run without --confirm. That flag is your attestation that the user confirmed the exact action in chat, so ask first, every time: amount, merchant, and what it is for.

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.
