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 | $0.00115 | $0.02853 |
| Opus 5 | $0.00057 | $0.01426 |
| Sonnet 5 | $0.00023 | $0.00571 |
| Haiku 4.5 | $0.00012 | $0.00285 |
Grade A, and why
openclaw-crypto-payments 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 12d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenClaw Crypto Payments v2.0
x402 USDC micropayments for AI agents. 5 tools. No accounts. No Stripe. Pay-per-call native. Base + Ethereum.
| Tool | Purpose | Free |
|---|---|---|
create_payment |
Generate a USDC payment request with amount, description, and expiry | Yes |
verify_payment |
Confirm a payment was received on-chain and mark it as settled | Yes |
get_balance |
Check current USDC balance across connected wallets | Yes |
list_transactions |
Payment history with timestamps, amounts, and payer addresses | Yes |
generate_invoice |
Create a formatted invoice for a completed session or batch of calls | Yes |
What's New in v2.0
- CryptoPay Protocol -- Implements the x402 HTTP micropayment standard. AI agents can autonomously pay for API calls without human intervention or account setup.
- Multi-chain Support -- Base (preferred, <$0.01 gas), Ethereum mainnet (for larger amounts), and Polygon (low gas alternative).
- AutoSettle -- Payments are verified on-chain and automatically marked settled without manual confirmation. No webhook setup required.
- AgentPay Mode -- Designed for AI-to-AI payments. An agent can create a payment, receive it from another agent, verify it, and proceed — all in one tool chain.

This skill activates when a user says any of these:
- "charge USDC", "x402 payment", "pay-per-call", "crypto payment for API", "micropayment"
- "verify this payment", "check if received", "confirm USDC transaction", "payment confirmed"
- "USDC balance", "wallet balance", "how much USDC", "check balance", "available funds"
- "payment history", "list transactions", "all payments received", "USDC transactions"

- "x402", "ERC-20 payment", "Base chain", "USDC on Base", "stablecoin payment"
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.
