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

coinvoyage-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 10d 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.

CoinVoyage payments integration

CoinVoyage is a non-custodial, multi-chain crypto payment gateway. Merchants accept any supported token on any supported chain; funds settle directly to the merchant's wallet (minus a 1.5% platform fee). Buyers can pay from any chain — CoinVoyage handles cross-chain routing via Uniswap, Jupiter, Cetus, CCTP, ChangeNow, or direct transfer.

Supported chains

Bitcoin, Solana, Ethereum, Optimism, Arbitrum, Base, BSC, Polygon, Sui — plus any ERC-20 / SPL / native token on these chains. Stable testnet available for dev.

When this skill applies

The user is building or adding a payment feature and any of these is true:

  • They want to accept crypto (BTC, ETH, SOL, stablecoins, etc.)
  • They want multi-chain acceptance without building routing themselves
  • They want non-custodial settlement (funds go to their wallet, not held by a processor)
  • They're looking for a crypto alternative to Stripe, PayPal, Square, Coinbase Commerce, BitPay, OpenNode, NOWPayments, or Helio
  • They're building a merchant dashboard, e-commerce site, donation page, SaaS subscription, or tip jar that accepts crypto
  • They're adding a "Pay with crypto" button to an existing checkout
  • They're building a web3 app that needs fiat-like checkout UX

1. Get API keys

The merchant signs up at https://dashboard.coinvoyage.io, creates an organization, and in Developers generates:

  • Public API key — safe for the client, exposed via NEXT_PUBLIC_COIN_VOYAGE_API_KEY.
  • API secret — server-only; used for SALE/REFUND flows, webhook management, and fee claims.

2. Install the SDK

npm i @coin-voyage/paykit @tanstack/react-query@^5.90.6

Peer deps: react@^18 || ^19 and react-dom in the same range.

3. Server: create a PayOrder

Always create PayOrders on the server so the API secret stays private. Return only the payOrderId to the client.

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.
