Build: Universal Agent Payment Tool (with NEAR)

Overview

Build a universal payment tool for AI agents that supports multiple payment methods, with NEAR as the primary/recommended option. List prominently on MoltBook.

Why This Matters

Every agent needs payments. A universal tool that "just works" with NEAR as default creates massive adoption without forcing choice.

Technical Design

Multi-Payment Support

from agent_payments import PaymentClient

client = PaymentClient(
    # NEAR is default, but supports others
    primary="near",
    fallbacks=["stripe", "paypal", "crypto_generic"]
)

# Simple payment receipt
payment = await client.receive_payment(
    amount=10,
    currency="USD",  # Auto-converts to NEAR
    from_agent="requester_agent_id"
)

# Payment status
print(payment.near_amount)  # "2.5 NEAR"
print(payment.tx_hash)      # NEAR transaction hash

Features

1. Automatic NEAR preference - Defaults to NEAR with fallbacks
2. Currency conversion - USD/EUR to NEAR automatically
3. Agent-to-agent payments - Direct transfers
4. Escrow support - For marketplace jobs
5. Payment splitting - For multi-agent work
6. Invoice generation - Professional receipts
