What this skill does
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.

Using Services 1. Pick an origin — or search Check the Available Services table below first. If any origin clearly covers the task, skip search entirely and jump to step 2 (discover). Examples: Task Origin (skip search) ------ --------------------- Look up a person or company stableenrich.dev Generate an image or video stablestudio.dev Get Instagram/TikTok data stablesocial.dev Send an email stableemail.dev Upload a file stableupload.dev Only use search when none of the listed origins fit: Example: npx agentcash@latest search "send physical mail" or npx agentcash@latest search "generate music" Returns matching origins with endpoints and pricing. Default output is JSON (--format pretty for human-readable). 2. Discover endpoints on a service Example: npx agentcash@latest discover https://stableenrich.dev Read the output carefully. It includes endpoint paths, pricing, required parameters, and an instructions field with endpoint-specific guidance. 3. Check a specific endpoint before calling it Returns the request and response schema plus pricing guidance. Use this before fetch to avoid 400 errors from wrong field names. 4. Make the request fetch handles both paid routes and SIWX routes. …
