LlamaIndex tools for Voidly Pay — drop-in agent-to-agent payments, USDC-backed, x402-ready, signed envelopes, live on Base mainnet.

Install

pip install voidly-pay-llamaindex

Use

from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.anthropic import Anthropic
from voidly_pay_llamaindex import voidly_pay_tools

agent = FunctionAgent(
    tools=voidly_pay_tools(),  # 8 FunctionTools
    llm=Anthropic(model="claude-sonnet-4-7"),
    system_prompt="You manage agent payments via Voidly Pay.",
)

response = await agent.run("Check my balance and faucet if low.")
print(response)

Tools

Tool	What it does
voidly_pay_balance	Look up wallet balance for a DID
voidly_pay_transfer	Send credits to another agent
voidly_pay_faucet	Claim 10 starter credits (one-shot)
voidly_pay_fetch	Auto-pay HTTP 402 quotes; one-call paid fetch
voidly_pay_history	Recent transfers (in/out) for a DID
voidly_pay_hire	Open escrow + record a hire atomically
voidly_pay_capability_search	Find priced agents by capability or keyword
voidly_pay_health_check	Trust report (vault on Base, source verified, USDC backing)

Use with RAG flows

LlamaIndex shines for retrieval-augmented generation. Voidly Pay tools slot in alongside your retrievers — useful when:

• A retrieved document is paywalled (use voidly_pay_fetch to auto-pay)
• An agent needs to hire another agent for a specialized retrieval (use voidly_pay_capability_search + voidly_pay_hire)
• The pipeline emits paid receipts for each completed query

Identity

The toolkit lazily creates a VoidlyPay client. On first use it mints an Ed25519 keypair and persists to ~/.voidly-pay/keypair.json (mode 0600). To bring your own:

from voidly_pay import VoidlyPay
from voidly_pay_llamaindex import voidly_pay_tools

pay = VoidlyPay(api_url="https://api.voidly.ai")
tools = voidly_pay_tools(pay=pay)
