# Spraay Payments 💧 Multi-chain batch crypto payments, payroll, swaps, price feeds, invoices, and AI inference — all through one API. 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 payme
