Spraay is a protocol for sending crypto to multiple wallets in a single transaction. The x402 gateway exposes 57 paid endpoints and 5 free endpoints. Every paid call costs a micropayment via the x402 HTTP payment protocol. Free endpoints require no payment. ## Setup The gateway is live at `https://gateway.spraay.app`. Set your env: ```bash export SPRAAY_GATEWAY_URL="https://gateway.spraay.app" ``` No API key needed. Payments are made per-request via x402 (HTTP 402 → pay → retry). Your agent's wallet handles this automatically if you have a Coinbase CDP wallet or any x402-compatible facilitator. ## Supported Chains Base, Ethereum, Arbitrum, Polygon, BNB Chain, Avalanche, Solana, Unichain, Plasma, BOB, Bittensor. Payment contract (Base): `0x1646452F98E36A3c9Cfc3eDD8868221E207B5eEC` ## Core Workflows ### 1. Batch Payments (the main use case) Send tokens to multiple wallets in one transaction. ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/batch-payment" \ -H "Content-Type: application/json" \ -d '{ "recipients": [ {"address": "0xABC...123", "amount": "10"}, {"address": "0xDEF...456", "amount": "25"}, {"address": "0xGHI...789", "amount": "15"} ], "token": "USDC", "chain": "base" }' ``` If you get HTTP 402, the response contains payment instructions. Pay the facilitator, then retry with the payment proof header. ### 2. Token Prices ```bash # Free endpoint — no x402 payment needed curl "$SPRAAY_GATEWAY_URL/api/price?symbol=ETH" ``` Returns current USD price. Works for any major token symbol. ### 3. Token Balances ```bash curl "$SPRAAY_GATEWAY_URL/api/balance?address=0xABC...&chain=base" ``` ### 4. Token Swaps ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/swap-quote" \ -H "Content-Type: application/json" \ -d '{ "tokenIn": "ETH", "tokenOut": "USDC", "amount": "1.0", "chain": "base" }' ``` ### 5. ENS / Basename Resolution ```bash # Free endpoint curl "$SPRAAY_GATEWAY_URL/api/resolve?name=vitalik.eth" ``` Resolves ENS names and Base names to addresses. ### 6. Invoices ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/create-invoice" \ -H "Content-Type: application/json" \ -d '{ "recipient": "0xABC...123", "amount": "500", "token": "USDC", "chain": "base", "memo": "March consulting invoice" }' ``` ### 7. AI Chat Inference ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/ai/chat" \ -H "Content-Type: application/json" \ -d '{ "message": "Explain DeFi yield farming", "model": "openrouter/auto" }' ``` Powered by OpenRouter. Pay-per-query via x402. ### 8. Payroll ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/batch-payment" \ -H "Content-Type: application/json" \ -d '{ "recipients": [ {"address": "alice.eth", "amount": "3000"}, {"address": "bob.base", "amount": "2500"}, {"address": "0xCCC...999", "amount": "4000"} ], "token": "USDC", "chain": "base", "memo": "March 2026 payroll" }' ``` ENS and Basename addresses resolve automatically. ## Communication Endpoints (Paid) ### Email ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/email/send" \ -H "Content-Type: application/json" \ -d '{ "to": "[email protected]", "subject": "Payment Confirmation", "body": "Batch payment of 50,000 USDC sent to 12 recipients on Base." }' ``` ### XMTP Messaging ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/xmtp/send" \ -H "Content-Type: application/json" \ -d '{ "to": "0xRecipient...", "message": "Your payment of 500 USDC has been sent via Spraay." }' ``` ### Webhooks ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/webhook/send" \ -H "Content-Type: application/json" \ -d '{ "url": "https://your-app.com/webhook", "payload": {"event": "payment_complete", "txHash": "0x..."} }' ``` ## Infrastructure Endpoints (Paid) ### RPC Relay (7 chains via Alchemy) ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/rpc/relay" \ -H "Content-Type: application/json" \ -d '{ "chain": "base", "method": "eth_blockNumber", "params": [] }' ``` ### IPFS Upload (via Pinata) ```bash curl -X POST "$SPRAAY_GATEWAY_URL/api/ipfs/pin" \ -H "Content-Type: application/json" \ -d '{ "content": "Hello from Spraay!", "name": "my-file.txt" }' ``` ## Free Endpoints (No Payment Required) These 5 endpoints work without x402 payment: - `GET /api/price?symbol=ETH` — Token prices - `GET /api/resolve?name=vitalik.eth` — ENS/Basename resolution - `GET /api/health` — Gateway health check - `GET /api/chains` — List supported chains - `GET /api/endpoints` — List all available endpoints ## x402 Payment Flow 1. Call any paid endpoint 2. Receive HTTP 402 with payment details (amount, facilitator address, token) 3. Send micropayment to the facilitator 4. Retry the original request with the `X-PAYMENT` header containing payment proof 5. Receive your response Typical cost per call: fractions of a cent in USDC on Base. ## Error Handling - `402` — Payment required. Follow the payment instructions in the response body. - `400` — Bad request. Check your parameters. - `404` — Endpoint not found. - `500` — Server error. Retry after a moment. Always check the HTTP status code before processing the response body. ## Tips - Batch payments save 60-80% on gas vs individual transfers. - Use the free `/api/price` endpoint to calculate USD values before sending. - Resolve ENS/Basenames before batching to validate all addresses. - Chain defaults to "base" if not specified. - Token defaults to "USDC" if not specified. - The gateway supports any ERC-20 token plus native ETH. ## Links - App: https://spraay.app - Gateway: https://gateway.spraay.app - Docs: https://docs.spraay.app - GitHub: https://github.com/plagtech - Twitter: https://twitter.com/Spraay_app - MCP Server: https://smithery.ai/server/@plagtech/spraay-x402-mcp
