Pay-per-call x402/MPP APIs (USDC on Base, Solana, Tempo). No API keys—wallet pays per request. If the task matches a SERVICES origin below, SKIP search and go straight to discover → fetch. Only search when NO listed origin fits. SERVICES: stableenrich (people/company, web search, scraping, Maps, LinkedIn, email verify, news), stablesocial (TikTok, Instagram, YouTube, Facebook, Reddit, LinkedIn, GitHub), stablestudio (AI image/video), stableupload (file/site hosting), stableemail (email, inboxes, subdomains), stablephone (AI calls, phone numbers), stablejobs (jobs), stabletravel (travel), stablebrowser (browser automation). TRIGGERS: research, enrich, scrape, search the web, generate image, video, social media, send email, phone call, travel, jobs, find contact, find API, x402, mpp, agentcash

What this skill does
AgentCash Wallet & Paid APIs Call any x402-protected API with automatic wallet authentication and payment. No API keys or subscriptions needed. Setup If the agentcash MCP is not yet installed, see rules/getting-started.md for installation and wallet setup. Wallet Management Your wallet is auto-created on first use and stored at ~/.agentcash/wallet.json. Check Balance Returns total USDC balance across supported networks. Use this before paid calls to confirm funds are available. Redeem Invite Code One-time use per code. Credits added instantly. Run agentcash.getbalance() after to verify. Deposit USDC 1. Call agentcash.listaccounts() to get per-network wallet addresses and deposit links 2. Send USDC on Base network (eip155:8453) or Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) to the matching address 3. Or open the returned deposit link for the selected network Important: Only Base or Solana network USDC. Other networks or tokens will be lost. Calling Paid APIs 1.

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: Returns matching origins with endpoints and pricing (the top match often includes schema so you can call fetch immediately). CLI equivalent: npx agentcash@latest search "<query>". 2. Discover endpoints Returns all endpoints, pricing, and usage instructions. Read the instructions field — it has critical endpoint-specific guidance. 3. Check schema (optional) Returns full request/response JSON schemas and pricing for a specific endpoint. 4. …
