How this service works
Generate an EIP-681 crypto payment link for end-user wallets. Agent pays a micro-fee via x402. Generic mode: pass payTo and token in the body. Optional mode=botpay uses BotPay vending infrastructure.
Output
Returns an EIP-681 payment URI string that encodes the recipient address, ERC-20 token contract, amount (in token smallest units), and network — ready to embed in a QR code or shared directly with an end-user wallet app. May include a BotPay vending proxy URI if mode=botpay.
Example use cases
Example prompt
“Create an EIP-681 payment link in generic mode so my customer can pay 1.00 USDC to my wallet 0xAbC1234...5678 on Base network — tag it with session ID order-9921.”
Technical details
Endpoint
POSThttps://agent-api-task.vercel.app/agent/v1/vending/create-payment-linkWhen to prefer
Use this endpoint when you need to programmatically generate EIP-681-compliant payment URIs for end-user wallets on Base (USDC) or BSC (USDT), especially when building checkout flows, vending machines, or invoice systems that need on-chain-encoded payment requests. Prefer the botpay mode when integrating with BotPay vending infrastructure for FX conversion or managed payment routing.
Side effects
- Invalid or missing payTo address with no server-side DEFAULT_PAY_TO fallback — returns error
- Unsupported network value (not 'base' or 'bsc') — schema validation failure
- Invalid ERC-20 token contract address format — malformed URI or error response
- x402 micro-fee payment failure — request rejected before processing
- Amount value is non-numeric or negative — encoding error
- BotPay infrastructure unavailable in botpay mode — upstream error

|---|---|---|
| mode | string | generic=EIP-681 builder; botpay=BotPay vending payment-uri proxy |
| payTo | string | Merchant recipient (0x) for product payment. Not the x402 API fee recipient. Falls back to server DEFAULT_PAY_TO. |
| token | string | ERC-20 contract address (which coin). Does NOT identify product type. Default: USDC on base, USDT on bsc. |
| amount | string | Payment amount only (e.g. "1.00"). Not a product SKU. Encoded on-chain as token smallest units. |
| network | string | Blockchain for end-user payment. base=USDC, bsc=USDT by default. |
| currency | string | Informational in generic mode. Does not select product. Botpay mode may use for FX conversion. |
| sessionId | string | Optional business order id. Link off-chain product info to this id; not embedded in the payment URI. |
