{"slug": "your-ai-agent-shouldn-t-need-to-understand-crypto-to-pay-for-apis", "title": "Your AI agent shouldn't need to understand crypto to pay for APIs", "summary": "Cinderwright has launched a proxy service that lets AI agents call over 2,800 paid APIs — including weather, translation, and Bitcoin price lookups — without implementing any crypto payment logic. Developers deposit USDC once on Base, then describe their task via a single API call, and the proxy handles payment signing, protocol selection (x402, L402, or MPP), and returns the result. The service also offers an MCP server for direct integration with Claude, with each call costing the service price plus a 10% markup.", "body_md": "Here's the situation. There are 2,811 paid AI services live today: weather APIs, translation, sentiment analysis, Bitcoin prices, DNS lookup, web extraction, and hundreds more. They all use protocols like x402 (Coinbase/USDC), L402 (Bitcoin Lightning), or MPP (Stripe/Tempo).\n\nThe problem: to call any of them from an agent, you have to implement payment signing. That means wallet keys, EIP-3009 signatures, gas fees, network switching. Most developers just skip these services entirely and pay $100/month for a conventional API that wraps the same data.\n\nWe built a proxy so you don't have to deal with any of that.\n\nDeposit USDC once. Describe what you need. The proxy finds the right service, signs the payment, and returns the result.\n\n```\n# Step 1: Create an account (free)\ncurl -X POST https://api.ideafactorylab.org/proxy/setup \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"wallet\": \"0xYourBaseWallet\"}'\n# Returns: { \"key\": \"sk_cw_...\", \"deposit_address\": \"0x...\" }\n\n# Step 2: Deposit USDC on Base to that address\n# Even $5 gets you hundreds of calls\n\n# Step 3: Describe what you need\ncurl -X POST https://api.ideafactorylab.org/proxy/do \\\n  -H \"X-CW-Key: sk_cw_your_key\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"task\": \"Bitcoin price now\"}'\n```\n\nResponse:\n\n```\n{\n  \"symbol\": \"BTC\",\n  \"price_usd\": 67475,\n  \"change_24h\": -4.94,\n  \"via\": \"Cinderwright proxy/do\"\n}\n```\n\nNo wallet management in your agent code. No signing logic. No tracking which chain you're on.\n\n```\n# Weather\ncurl -X POST https://api.ideafactorylab.org/proxy/do \\\n  -H \"X-CW-Key: sk_cw_your_key\" \\\n  -d '{\"task\": \"weather in Tokyo\"}'\n# {\"temp_c\":\"22\",\"condition\":\"Heavy rain\",\"humidity\":\"96\"}\n\n# Translation\ncurl -X POST https://api.ideafactorylab.org/proxy/do \\\n  -H \"X-CW-Key: sk_cw_your_key\" \\\n  -d '{\"task\": \"translate hello world to Japanese\"}'\n# {\"translated\":\"こんにちは世界\"}\n\n# Summarization\ncurl -X POST https://api.ideafactorylab.org/proxy/do \\\n  -H \"X-CW-Key: sk_cw_your_key\" \\\n  -d '{\"task\": \"summarize this\", \"context\": \"paste your text here\"}'\n\n# Sentiment\ncurl -X POST https://api.ideafactorylab.org/proxy/do \\\n  -H \"X-CW-Key: sk_cw_your_key\" \\\n  -d '{\"task\": \"sentiment of this review\", \"context\": \"Great product, slow shipping\"}'\n# {\"sentiment\":\"mixed\",\"confidence\":0.82}\n```\n\nEach call costs the service price plus 10% markup. Bitcoin price: $0.011. Weather: $0.011. Translation: $0.022. Summarization: $0.033.\n\nInstall the MCP server:\n\n```\nnpx cinderwright-mcp-server\n```\n\nAdd to your `claude_desktop_config.json`\n\n:\n\n```\n{\n  \"mcpServers\": {\n    \"cinderwright\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"cinderwright-mcp-server\"],\n      \"env\": { \"CW_KEY\": \"sk_cw_your_key_here\" }\n    }\n  }\n}\n```\n\n**Mac:** `~/Library/Application Support/Claude/claude_desktop_config.json`\n\n**Windows:** `%APPDATA%\\Claude\\claude_desktop_config.json`\n\nThen in Claude: *\"Get the Bitcoin price\"* or *\"Translate this to Spanish\"* and the `proxy_do`\n\ntool handles everything. The call routes through your proxy balance automatically.\n\n2,811 services across three protocols:\n\n| Protocol | Count | Payment |\n|---|---|---|\n| x402 | 1,503 | USDC on Base (Coinbase) |\n| L402 | 1,185 | Bitcoin Lightning |\n| MPP | 92 | Stripe / Tempo |\n\nAll graded A-F weekly by a canary tester that actually calls each service, checks the response, and records the result.
