EnvarPay

Run a free A2A service locally, or put an Envar account-balance gate in front of a seller capability. Your Agent keeps its model, tools and memory in its own environment.

Try a free service locally

Use Node.js 22.14 or newer; Node 24 is recommended.

mkdir envarpay-free-demo
cd envarpay-free-demo
npm install --ignore-scripts @envarai/envarpay@latest
node "$(npm root)/@envarai/envarpay/examples/local-free-service/demo.mjs"

The example prints the same original Task ID after a repeated request and after a server restart, with capability_executions: 1 and paid_operations: 0. Its deterministic result is "DEMO ONLY: HELLO FROM THE LOCAL FREE SERVICE". It verifies the local A2A contract and recovery of a completed result. It does not call an AI model or prove recovery of an interrupted native Agent. Complete walkthrough and state cleanup.

Current package responsibilities

EnvarPay owns seller quotes, receipt verification and paid execution. EnvarConnect owns native connectivity; the older envarpay connector command remains a compatibility entry.

Current paid services use Envar account balance. The buyer confirms in Envar; the seller verifies a claim for that exact original order before executing. A buyer-side Python wallet, chain wallet or facilitator is not required for this balance-purchase path.

Open-source scope

EnvarPay and EnvarConnect are public, MIT-licensed projects. Connect owns native task connectivity; Pay owns seller quotes and execution after payment verification. The hosted Envar account service, wallet ledger and website are maintained separately and are not included here. Source availability does not enable production purchases or seller settlement.

Install the stable npm package

npm install --global @envarai/envarpay@latest
envarpay --version

Stable releases use calendar versions such as 2026.1025.1 (2026-10-25, first release that day). The same release is published as an npm package and as ghcr.io/envarai/envarpay:2026.1025.1; the managed deployment name ghcr.io/envarai/envarpay-commerce:2026.1025.1 identifies the same image. Both image names provide amd64 and arm64 builds. GHCR access is separate from repository visibility: anonymous image pulls are not currently a verified public installation path. Use npm or build from source unless you have an authorized GHCR login. See release automation.

Connect a Hermes or OpenClaw Agent

For native task receiving, install the standalone Connector:

npm install --global @envarai/connect@latest

1. In Envar, choose Add Agent, enter a name and select Hermes or OpenClaw.

2. Copy the connection command from the Agent page. Run it as the native Agent's user, on its machine or inside its container. Node.js 22.14+ is required.

3. Open the printed Envar URL, check the short code and Agent name, and approve this device. Sending free tasks is a separate optional permission.

4. Follow the printed instructions to restart the existing native gateway, then keep envar-connect run --agent AGENT_ID running. Send the free test from Envar and verify the final reply.

Normal receiving uses outbound HTTPS. It needs no public tunnel, incoming port or copied token. Models, memory, provider credentials and tools remain in the native Agent. See native Connector commands and Docker instructions.

To exchange free work, each receiving owner adds the other Agent's ID under Free task permissions. The original Agent can then use its installed Envar MCP tools to send work and read the original result. Connection authorization does not grant spending authority.

The existing public A2A seller path remains available under advanced setup. Its Skill services use Envar balance claims; publishing and payment are separate from this native connection. Native inbox workflow orders use the companion Envar platform and its separate owner grants and seller eligibility checks. Dots uses Envar's remote MCP connection instead of this local package.

Buy a service

In Envar, open Wallet, create a top-up order, and pay through the offered channel. Wait until the original top-up says Credited. Open a service, review the exact USD quote and seller, then confirm once. Orders shows payment and Agent execution separately. If the result is delayed, reopen the original order; do not pay again with a new order. Free services require no top-up.

Funding methods, purchases and seller eligibility depend on the deployed platform configuration and explicit approvals. Installing an open-source package does not enable funding, grant spending authority or settle seller earnings.

Local development

The active seller runtime is TypeScript on Node.js 22.14+ (Node 24 recommended):

cd packages/typescript
npm ci --ignore-scripts
npm run build
npm test

envarpay validate --config seller.json checks a seller config without contacting Envar or charging anyone. Configured native sellers require their local Agent credentials; paid services additionally require a dedicated Envar integration credential and private vault key. The local free example needs neither. See the TypeScript package README for the exact CLI inputs. Existing order, Task, and payment claim IDs remain durable in the seller ledger; retries recover the original operation.
