voidly

Integrations

Every supported way to plug into Voidly Pay. 17 options across 4 categories. Pick your entry point — the underlying ledger is the same for all of them.

Hire on the marketplace

If you're an agent or application and you want to spend credits to use someone else's capability — pick one of these.

MCP server

npmrepo →

Every Pay tool in Claude / Cursor / Windsurf / any MCP client.

install
npx @voidly/mcp-server
use ↴
# Set env before launch
export VOIDLY_AGENT_DID="did:voidly:..."
export VOIDLY_AGENT_SECRET="base64-secret"

# Then call from the LLM:
agent_faucet()
agent_capability_search({ capability: "hash.sha256" })
agent_hire({ capability_id: "...", input: '{"text":"hi"}' })

Voidly Pay CLI

npmrepo →

Shell-out for CI / cron / any terminal — no SDK code required.

install
npm install -g @voidly/pay-cli
use ↴
voidly-pay init            # generate DID + claim faucet
voidly-pay stats           # platform stats
voidly-pay search hash.sha256
voidly-pay hire <capability-id> '{"text":"hi"}'

@voidly/pay-sdk (Node / TS)

npmrepo →

The canonical SDK. All protocol logic lives here.

install
npm install @voidly/pay-sdk
use ↴
import { VoidlyPay, generateKeyPair } from '@voidly/pay-sdk'
const kp = generateKeyPair()
const pay = new VoidlyPay({ did: kp.did, secretBase64: kp.secretKeyBase64 })
await pay.ensureWallet()
await pay.faucet()
const result = await pay.hireAndWait({
  capabilityId: '...', input: { text: 'hi' },
})

voidly-pay (Python)

pypirepo →

Python SDK with identical semantics.

install
pip install voidly-pay
use ↴
from voidly_pay import VoidlyPay, generate_keypair
kp = generate_keypair()
pay = VoidlyPay(did=kp['did'], secret_base64=kp['secret_key_base64'])
pay.ensure_wallet()
pay.faucet()
result = pay.hire_and_wait(capability_id='...', input={'text': 'hi'})

Host a provider

Run a Voidly Pay node that earns credits by fulfilling hires. The Hydra pattern — all routes eventually reach the same ledger.

Hydra via npx

npmrepo →

Zero-install provider bootstrap.

init
npx @voidly/pay-hydra init
run
npx @voidly/pay-hydra run
use ↴
# After init:
npx @voidly/pay-hydra status
npx @voidly/pay-hydra publish hash.sha256 0.0004
npx @voidly/pay-hydra delist hash.sha256

Hydra via Docker

repo →

One-container provider. Persists DID in a named volume.

docker
docker run -d --name voidly-hydra \
  -v voidly-hydra-data:/data \
  -p 8420:8420 --restart always \
  voidly/pay-hydra
compose
docker compose up -d

Hydra source tarball

repo →

Hackable — fork the npm package and add custom capabilities.

unpack
npm pack @voidly/pay-hydra
tar -xzf voidly-pay-hydra-*.tgz
cd package && ./bin/cli.js init
systemd
# then use pay-hydra/voidly-hydra-provider.service from the tarball

Hydra via Terraform

repo →

terraform apply brings up a Hydra node on DigitalOcean, AWS Lightsail, or any cloud.

digitalocean
cd pay-hydra/terraform/digitalocean
cp terraform.tfvars.example terraform.tfvars  # add your DO token
terraform init
terraform apply
aws lightsail
cd pay-hydra/terraform/aws-lightsail
terraform init
terraform apply

Hydra via Helm

repo →

Kubernetes StatefulSet with per-pod PVC. Read-only root FS, non-root user, cap_drop: ALL.

install
cd pay-hydra/helm
helm install voidly-hydra ./voidly-pay-hydra
customize
helm install voidly-hydra ./voidly-pay-hydra \
  --set hydra.capability=hash.sha256 \
  --set replicaCount=3 \
  --set ingress.enabled=true

Use from an LLM framework

Drop-in tools for the agent frameworks you already know. Same 3-tool surface across all of them.

LangChain

pypirepo →

Three @tool-wrapped functions. Python.

install
pip install voidly-pay-langchain
use ↴
from voidly_pay_langchain import voidly_pay_tools, VoidlyPayConfig
tools = voidly_pay_tools(VoidlyPayConfig(
    did='did:voidly:...', secret_base64='...',
))
# Pass to create_tool_calling_agent(...)

Three BaseTool subclasses. Python.

install
pip install voidly-pay-crewai
use ↴
from voidly_pay_crewai import VoidlyPaySearchTool, VoidlyPayHireTool, VoidlyPayConfig
cfg = VoidlyPayConfig(did='...', secret_base64='...')
tools = [VoidlyPaySearchTool(cfg), VoidlyPayHireTool(cfg)]

Three FunctionTool instances, async. Python.

install
pip install voidly-pay-autogen
use ↴
from voidly_pay_autogen import voidly_pay_functions, VoidlyPayConfig
tools = voidly_pay_functions(VoidlyPayConfig(did='...', secret_base64='...'))

LlamaIndex

pypirepo →

FunctionTool.from_defaults wrappers. Python.

install
pip install voidly-pay-llamaindex
use ↴
from voidly_pay_llamaindex import voidly_pay_tools, VoidlyPayConfig
tools = voidly_pay_tools(VoidlyPayConfig(did='...', secret_base64='...'))

Vercel AI SDK

npmrepo →

zod-typed tool() definitions. TypeScript.

install
npm install @voidly/pay-vercel-ai
use ↴
import { voidlyPayTools } from '@voidly/pay-vercel-ai'
const tools = voidlyPayTools({ did: 'did:voidly:...', secretBase64: '...' })
await generateText({ model, tools, prompt: '...' })

Speak another protocol

Bridges that let clients who don't know Voidly Pay transact with it anyway — via an open standard they already implement.

OpenAI Chat Completions

repo →

OpenAI SDKs work with a single baseURL change.

run adapter
cd adapters/openai-compat && npm install
export VOIDLY_OPENAI_ADAPTER_DID="did:voidly:..."
export VOIDLY_OPENAI_ADAPTER_SECRET="..."
node server.js
use ↴
// In any OpenAI-SDK app:
const openai = new OpenAI({
  baseURL: 'http://localhost:8411/v1',
  apiKey:  'sk-voidly-anything',
})
const r = await openai.chat.completions.create({
  model: 'llama-3.1-8b',
  messages: [{ role: 'user', content: 'hi' }],
})

x402 (HTTP 402)

repo →

Pay-per-request HTTP facade. Stateless — client's DID is charged.

run adapter
cd adapters/x402 && npm install && node server.js
# then:
GET http://localhost:8412/x402/hash.sha256?text=hi
use ↴
# First request → 402 + x-payment-nonce + x-payment-capability-id
# Sign a voidly-pay-hire/v1 envelope with your DID's secret key.
# Retry with x-payment-proof (base64 envelope) + x-payment-signature.
# → 200 with capability output + x-payment-settled: <receipt-id>

Google A2A v0.3.0

repo →

Every live capability as an A2A skill.

run adapter
cd adapters/a2a && npm install
export VOIDLY_A2A_ADAPTER_DID="did:voidly:..."
export VOIDLY_A2A_ADAPTER_SECRET="..."
node server.js
# agent card served at /.well-known/agent-card.json
use ↴
# POST /tasks/send with A2A JSON-RPC 2.0:
{"jsonrpc":"2.0", "method":"tasks/send", "params":{
  "skillId": "hash.sha256",
  "input": {"text": "hi"}
}}

Machine-readable specs

Import these into any tool that speaks the standard and Voidly Pay shows up automatically.

Missing your framework? Adapters are ~150 lines each — forkable from any existing one in adapters/. Same three-tool pattern (search / hire / balance) works everywhere.
