PayAI does not yet support v2 for Solana.\n\nMemo Requirement: The USDC transfer transaction must include a Solana Memo program instruction with the value SP3ND Order: (e.g. SP3ND Order: ORD-1234567890). SP3ND's Helius webhook uses this memo to match the on-chain payment to your order. Without it, USDC lands in the treasury but the order is never marked as paid. Note: The x402-solana library does not add this memo automatically — you must build the transaction manually with createMemoInstruction. See the code example below.\n\nYour agent must:\n\nRead the PAYMENT-REQUIRED header from the 402 response and base64-decode it\nBuild a VersionedTransaction (v0) with:\n\nA USDC createTransferCheckedInstruction (6 decimals)\nA createMemoInstruction with SP3ND Order: \nfeePayer set to accepts[0].extra.feePayer (PayAI's wallet — not your agent)\n\n\nSign with your agent's keypair (tx.sign([keypair]))\nBuild an x402 v1 payment payload and call the facilitator's /verify then /settle endpoints\nPoll GET /getPartnerOrders until the order status is Paid (typically within 60 seconds)\n\nPayment confirmation:\n\nAfter the facilitator settles the transaction on-chain, SP3ND's Helius webhook detects the USDC transfer + memo and marks the order as paid. Your agent confirms by polling:\n\nGET /getPartnerOrders\nX-API-Key: \nX-API-Secret: \n\nPoll every ~5 seconds. When the order's status changes to Paid, you're done:\n\n{\n \"order_number\": \"ORD-1234567890\",\n \"status\": \"Paid\",\n \"total_amount\": 30.74,\n \"transaction_signature\": \"5xYz...abc\"\n}\n\nThe order is now paid. SP3ND purchases the product from Amazon and ships it.\n\nWhy polling instead of a second payAgentOrder call? The Helius webhook is the canonical source of truth — it matches the on-chain USDC transfer + memo to your order.

Instant API credentials.\n\nPOST /registerAgent\nContent-Type: application/json\n\n{\n \"agent_name\": \"MyShoppingBot\",\n \"solana_public_key\": \"YourAgentWa11etPublicKeyHere\",\n \"contact_email\": \"dev@example.com\",\n \"description\": \"Autonomous Amazon shopping agent\"\n}\n\n\nResponse:\n\n{\n \"success\": true,\n \"partner_id\": \"abc123\",\n \"api_key\": \"sp3nd_xxxxxxxxxxxxxxxxxxxxxxxxxxxx\",\n \"api_secret\": \"sp3nd_sec_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\",\n \"message\": \"Agent registered successfully. Save your API secret — it will not be shown again.\"\n}\n\n\nSave your api_secret immediately. It is shown only once. If lost, use regeneratePartnerSecret to get a new one.\n\nStep 2: Create a Cart\n\nIMPORTANT — Use the correct Amazon TLD for the shipping country! Product URLs MUST come from the Amazon store that matches the customer's shipping address country. Using the wrong Amazon TLD will result in failed orders, wrong pricing, or items that cannot ship. See the Amazon TLD by Country table below for the full mapping.\n\nPOST /createPartnerCart\nContent-Type: application/json\nX-API-Key: \nX-API-Secret: \n\n{\n \"items\": [\n {\n \"product_id\": \"B08XYZ123\",\n \"product_title\": \"Example Product\",\n \"product_url\": \"https://amazon.com/dp/B08XYZ123\",\n \"quantity\": 1,\n \"price\": 29.99\n }\n ]\n}\n\n\nExample for a customer in Germany:\n\n{\n \"items\": [\n {\n \"product_url\": \"https://amazon.de/dp/B08XYZ123\",\n \"quantity\": 1\n }\n ]\n}\n\n\nResponse:\n\n{\n \"success\": true,\n \"cart\": {\n \"cart_id\": \"cart_abc123\",\n \"items\": [],\n \"subtotal\": 29.99,\n \"platform_fee\": 0.00,\n \"total_amount\": 29.99\n }\n}\n\n\nCarts expire after 30 minutes. Create them close to order time. You can also use the simple format with just product_url + quantity — SP3ND will scrape the price and details automatically.\n\nStep 3: Create an Order\nPOST /createPartnerOrder\nContent-Type: application/json\nX-API-Key: \nX-API-Secret: \n\n{\n \"cart_id\": \"cart_abc123\",\n \"customer_email\": \"customer@example.com\",\n \"shipping_address\": {\n \"name\": \"John Doe\",\n \"recipient\": \"John Doe\",\n \"address1\": \"123 Main St\",\n \"city\": \"San Francisco\",\n \"state\": \"CA\",\n \"postalCode\": \"94105\",\n \"zip\": \"94105\",\n \"country\": \"United States\",\n \"phone\": \"+14155551234\"\n }\n}\n\n\nRequired fields: customer_email and shipping_address.phone are both mandatory.\n\nResponse includes: order_id, order_number, total_amount\n\nStep 4: Pay with x402 (Autonomous)\n\nThis is the key step. The x402 protocol handles payment automatically:\n\nFirst call (no payment header):\n\nPOST /payAgentOrder\nContent-Type: application/json\nX-API-Key: \nX-API-Secret: \n\n{\n \"order_id\": \"\",\n \"order_number\": \"\"\n}\n\n\nResponse: HTTP 402 Payment Required\n\nThe payment requirements are returned in the PAYMENT-REQUIRED HTTP header as a base64-encoded JSON object (not in the response body). Decode it to get:\n\n{\n \"x402Version\": 1,\n \"scheme\": \"exact\",\n \"network\": \"solana\",\n \"resource\": \"https://us-central1-sp3nddotshop-prod.cloudfunctions.net/payAgentOrder\",\n \"accepts\": [{\n \"maxAmountRequired\": \"30740000\",\n \"amount\": \"30740000\",\n \"payTo\": \"2nkTRv3qxk7n2eYYjFAndReVXaV7sTF3Z9pNimvp5jcp\",\n \"asset\": \"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v\",\n \"maxTimeoutSeconds\": 300,\n \"extra\": {\n \"feePayer\": \"2wKupLR9q6wXYppw8Gr2NvWxKBUqm4PPJKkQfoxHDBg4\",\n \"order_number\": \"ORD-1234567890\"\n }\n }]\n}\n\n\nImportant details:\n\nextra.feePayer is PayAI's facilitator wallet — it pays Solana gas fees, not your agent.\nextra.order_number is used to build the required memo instruction.\nasset is the USDC mint address as a flat string (not an object).\nx402Version must be 1 with network: \"solana\" (not CAIP-2 format). PayAI does not yet support v2 for Solana.\n\nMemo Requirement: The USDC transfer transaction must include a Solana Memo program instruction with the value SP3ND Order: (e.g. SP3ND Order: ORD-1234567890). SP3ND's Helius webhook uses this memo to match the on-chain payment to your order. Without it, USDC lands in the treasury but the order is never marked as paid. Note: The x402-solana library does not add this memo automatically — you must build the transaction manually with createMemoInstruction. See the code example below.\n\nYour agent must:\n\nRead the PAYMENT-REQUIRED header from the 402 response and base64-decode it\nBuild a VersionedTransaction (v0) with:\nA USDC createTransferCheckedInstruction (6 decimals)\nA createMemoInstruction with SP3ND Order: \nfeePayer set to accepts[0].extra.feePayer (PayAI's wallet — not your agent)\nSign with your agent's keypair (tx.sign([keypair]))\nBuild an x402 v1 payment payload and call the facilitator's /verify then /settle endpoints\nPoll GET /getPartnerOrders until the order status is Paid (typically within 60 seconds)\n\nPayment confirmation:\n\nAfter the facilitator settles the transaction on-chain, SP3ND's Helius webhook detects the USDC transfer + memo and marks the order as paid. Your agent confirms by polling:\n\nGET /getPartnerOrders\nX-API-Key: \nX-API-Secret: \n\n\nPoll every ~5 seconds. When the order's status changes to Paid, you're done:\n\n{\n \"order_number\": \"ORD-1234567890\",\n \"status\": \"Paid\",\n \"total_amount\": 30.74,\n \"transaction_signature\": \"5xYz...abc\"\n}\n\n\nThe order is now paid. SP3ND purchases the product from Amazon and ships it.\n\nWhy polling instead of a second payAgentOrder call? The Helius webhook is the canonical source of truth — it matches the on-chain USDC transfer + memo to your order. Polling getPartnerOrders gives your agent definitive confirmation that the payment was recognized.\n\nStep 5: Track Order Status\nGET /getPartnerOrders?status=all\nX-API-Key: \nX-API-Secret: \n\nAgent Health Check\nGET /getAgentStatus\nX-API-Key: \nX-API-Secret: \n\n\nReturns your agent's stats: orders, revenue, fee rate, etc.\n\nFee Structure\nAgent Type\tPlatform Fee\nDefault agent\t0% — no platform fee\nCustom (set by admin)\tAdjustable per-agent\n\nThere are no payment processing fees — USDC transfers on Solana cost fractions of a cent in gas. Agents pay the product price + applicable tax only. Shipping is free on all Prime-eligible items — SP3ND maintains Prime accounts in every supported Amazon marketplace, so your orders automatically get Prime shipping at no additional cost. Some surrounding regions served by a regional hub (e.g. Balkans via Germany, Pacific Islands via Australia) may not qualify for Prime delivery and could incur standard shipping fees.\n\nAmazon TLD by Country (CRITICAL)\n\nYou MUST use the correct Amazon domain for the customer's shipping country. Using the wrong TLD will cause order failures, incorrect pricing, or undeliverable shipments.\n\nCountry\tAmazon TLD\tExample URL\nUS United States\tamazon.com\thttps://amazon.com/dp/B08XYZ123\nGB United Kingdom\tamazon.co.uk\thttps://amazon.co.uk/dp/B08XYZ123\nCA Canada\tamazon.ca\thttps://amazon.ca/dp/B08XYZ123\nDE Germany\tamazon.de\thttps://amazon.de/dp/B08XYZ123\nFR France\tamazon.fr\thttps://amazon.fr/dp/B08XYZ123\nES Spain\tamazon.es\thttps://amazon.es/dp/B08XYZ123\nIT Italy\tamazon.it\thttps://amazon.it/dp/B08XYZ123\nNL Netherlands\tamazon.nl\thttps://amazon.nl/dp/B08XYZ123\nBE Belgium\tamazon.com.be\thttps://amazon.com.be/dp/B08XYZ123\nPL Poland\tamazon.pl\thttps://amazon.pl/dp/B08XYZ123\nSE Sweden\tamazon.se\thttps://amazon.se/dp/B08XYZ123\nBR Brazil\tamazon.com.br\thttps://amazon.com.br/dp/B08XYZ123\nMX Mexico\tamazon.com.mx\thttps://amazon.com.mx/dp/B08XYZ123\nAU Australia\tamazon.com.au\thttps://amazon.com.au/dp/B08XYZ123\nIN India\tamazon.in\thttps://amazon.in/dp/B08XYZ123\nJP Japan\tamazon.co.jp\thttps://amazon.co.jp/dp/B08XYZ123\nSG Singapore\tamazon.sg\thttps://amazon.sg/dp/B08XYZ123\nAE UAE\tamazon.ae\thttps://amazon.ae/dp/B08XYZ123\nSA Saudi Arabia\tamazon.sa\thttps://amazon.sa/dp/B08XYZ123\nEG Egypt\tamazon.eg\thttps://amazon.eg/dp/B08XYZ123\nTR Turkey\tamazon.com.tr\thttps://amazon.com.tr/dp/B08XYZ123\nZA South Africa\tamazon.co.za\thttps://amazon.co.za/dp/B08XYZ123\nIE Ireland\tamazon.co.uk\tUse UK Amazon (also available: amazon.ie but limited selection)\nRegional Coverage — Which Amazon Store Serves Which Countries\n\nMany Amazon stores serve entire regions.
