--- name: agentcash-wallet description: | Manage your agentcash wallet and call any x402-protected API with automatic payment. No API keys, no subscriptions — just a funded wallet (USDC on Base). USE FOR: - Checking wallet balance before API calls - Redeeming invite codes for free credits - Getting deposit address for USDC - Discovering endpoints and pricing on any x402-protected origin - Making paid API requests via the agentcash CLI - Troubleshooting payment failures TRIGGERS: - "balance", "wallet", "funds", "credits" - "redeem", "invite code", "promo code" - "deposit", "add funds", "top up" - "discover", "endpoints", "what APIs", "pricing" - "insufficient balance", "payment failed" --- # agentcash Wallet & Paid APIs Call any x402-protected API with automatic payment. Payment is the authentication — no API keys or subscriptions needed. ## Setup If the agentcash CLI is not yet installed, see [rules/getting-started.md](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 ```bash npx agentcash wallet info ``` Returns wallet address, USDC balance, and deposit link. Always check before expensive operations. ### Redeem Invite Code ```bash npx agentcash wallet redeem YOUR_CODE ``` One-time use per code. Credits added instantly. Run `npx agentcash wallet info` after to verify. ### Deposit USDC 1. Get your wallet address via `npx agentcash wallet info` 2. Send USDC on **Base network** (eip155:8453) to that address 3. Or use the deposit UI: `https://x402scan.com/mcp/deposit/<wallet-address>` **Important**: Only Base network USDC. Other networks or tokens will be lost. ## Calling Paid APIs ### 1. Discover endpoints ```bash npx agentcash discover https://stableenrich.dev ``` Returns all endpoints, pricing, and usage instructions. **Read the `instructions` field** — it has critical endpoint-specific guidance. ### 2. Check schema (optional) ```bash npx agentcash check https://stableenrich.dev/api/apollo/people-search ``` Returns full request/response JSON schemas and pricing for a specific endpoint. ### 3. Make a paid request ```bash npx agentcash fetch https://stableenrich.dev/api/apollo/people-search -m POST -b '{"person_titles": ["CEO"], "person_locations": ["San Francisco"]}' ``` Payment is automatic: sends request, gets 402 challenge, signs USDC payment, retries with credential, returns result. Payments settle only on success (2xx) — failed requests cost nothing. ## Available Services | Origin | Service | What it does | |---|---|---| | `https://stableenrich.dev` | StableEnrich | Research APIs: Apollo (people/org), Exa (web search), Firecrawl (scraping), Grok (X/Twitter), Google Maps, Clado (LinkedIn), Serper (news/shopping), WhitePages, Reddit, Hunter (email verification), Influencer enrichment | | `https://stableupload.dev` | StableUpload | Pay-per-upload file hosting. 10MB/$0.02, 100MB/$0.20, 1GB/$2.00. 6-month TTL | | `https://stablestudio.dev` | StableStudio | AI image/video generation: GPT Image, Flux, Grok, Nano Banana, Sora, Veo, Seedance, Wan | | `https://stablesocial.dev` | StableSocial | Social media data: TikTok, Instagram, X/Twitter, Facebook, Reddit, LinkedIn. $0.06/call, async two-step | | `https://stableemail.dev` | StableEmail | Send emails ($0.02), forwarding inboxes ($1/mo), custom subdomains ($5) | | `https://stablephone.dev` | StablePhone | AI phone calls ($0.54), phone numbers ($20), top-ups ($15) | | `https://stablejobs.dev` | StableJobs | Job search via Coresignal | Run `npx agentcash discover <origin>` on any origin to see its full endpoint catalog. ## Quick Reference | Task | Command | |------|---------| | Check balance | `npx agentcash wallet info` | | Redeem code | `npx agentcash wallet redeem <code>` | | Discover endpoints | `npx agentcash discover <url>` | | Check pricing/schema | `npx agentcash check <url>` | | Paid POST request | `npx agentcash fetch <url> -m POST -b '{...}'` | | Paid GET request | `npx agentcash fetch <url>` | ## Tips - Always discover first — the `instructions` field has critical endpoint-specific patterns and required parameters. - Payments settle only on success (2xx) — failed requests cost nothing. - Use `npx agentcash check <url>` when unsure about request/response format. - Add `--format json` for machine-readable output, `--format pretty` for human-readable. - Add `-v` for verbose output to see payment details. - Network: Base (eip155:8453), Currency: USDC. ## Troubleshooting | Issue | Solution | |-------|----------| | "Command not found" | Run `npm install -g agentcash` | | "Insufficient balance" | Check balance, deposit USDC or redeem invite code | | "Payment failed" | Transient error — retry the request | | "Invalid invite code" | Code already used or doesn't exist | | Balance not updating | Wait for Base network confirmation (~2 sec) |
