Agentcash

This is pay-per-call API access with your crypto wallet instead of API keys. You get instant access to services like people enrichment, social media data, AI image generation, email sending, and file hosting, all billed per request in USDC on Base or Solana. The workflow is discover endpoints, check pricing, then fetch with automatic payment. It's genuinely useful if you're prototyping or need occasional access to expensive APIs without subscribing, though you'll want to check your balance before hitting video generation endpoints that can run a few dollars per call. The skill knows when to skip search and go straight to the right service, which keeps things fast.

AgentCash — Paid API Access

Call any x402-protected API with automatic wallet authentication and payment. No API keys or subscriptions required.

Wallet

Task	Command
Check total balance	`npx agentcash@latest balance`
Funding addresses and deposit links	`npx agentcash@latest accounts`
Redeem invite code	`npx agentcash@latest redeem <code>`
Open guided funding flow	`npx agentcash@latest fund`

Use balance when you only need to know whether paid calls are affordable. Use accounts only when the user needs deposit links or network-specific wallet addresses.

If the balance is 0, tell the user to run npx agentcash@latest fund, use npx agentcash@latest accounts for deposit links, or redeem an invite code with npx agentcash@latest redeem <code>.

Using Services
