A virtual MasterCard service for AI agents, funded and operated through Stellar payments. It is intended to let an agent make card-based purchases after setup.

Use it to onboard an agent, create or configure its payment wallet, check USDC funds, generate a card, and make supported payment requests.

It provides a guided onboarding flow for the wallet, account, identity, funding, and balance checks needed before using the card.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.02226
Opus 5.5	$0.00008	$0.00890
Sonnet 5.5	$0.00004	$0.00445
Haiku 4.5	$0.00002	$0.00223

Security

Grade A, and why

asgcard 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 2mo 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.

ASG Card Agent Skill

CRITICAL: Always use npx -y @asgcard/cli@latest (with @latest tag!) to ensure you are running the newest published version with all bug fixes.

⚠️ MANDATORY DATA RULES

NEVER use placeholder, test, or example data for email, phone, or name. You MUST ask the user for their real email address, phone number, and name before running any card creation or payment request command. If the user has previously provided their email/phone in the current conversation, you may reuse it. Otherwise, always ask first.

❌ WRONG: -e "[email protected]" -p "+12345678900" -n "Test User" ✅ RIGHT: Ask the user: "What email, phone number, and name should I use for the card?"

Onboarding (First Time)

Run the full 9-step onboarding wizard:

npx -y @asgcard/cli@latest onboard -y

Steps: Agent Skill → MCP Config → Wallet → API Registration → Telegram Identity → Wallet Activation → Fund Link → Balance Check → Summary

Canonical Flow (x402 / On-Chain USDC)

Onboard: Run asgcard onboard -y to set up wallet, MCP, and skill
Check wallet status: Use get_wallet_status MCP tool to verify wallet address and USDC balance
Fund wallet: Use asgcard fund-link or MCP get_fund_link to generate a deposit URL
Check pricing: Use get_pricing to see card and top-up pricing
Create a card: Use create_card with amount, name, email, and phone — all provided by the user
Manage cards: Use list_cards, get_card, get_card_details, freeze_card, unfreeze_card
Top up cards: Use fund_card to add funds to an existing card
Monitor: Use get_transactions and get_balance to track activity

Stripe MPP Flow (Fiat Payments via Stripe)

Use this flow when the user wants to pay with a regular credit/debit card instead of USDC.

Step 1 — Create a Stripe Session (one-time setup)

npx -y @asgcard/cli@latest stripe:session <USER_EMAIL>

The user's real email is required. This creates a session saved to ~/.asgcard/stripe-session.json.

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.
