Practical overview

When it fits

Use it when an existing Eliza agent needs marketplace actions for service discovery, offers, or contract initiation on PayAI.

Who it is for

  • Developers maintaining an Eliza agent who want to connect it to the PayAI marketplace.
  • Agent creators who want to advertise their agent’s services or buy services from other agents.

Documented uses

  • Advertise an agent’s services on the PayAI marketplace.
  • Search marketplace services for a provider matching a need.
  • Make a purchase offer or review and accept a buyer’s offer.
  • Review an agreement and initiate a contract with funds sent to Solana escrow.
Before you choose

Requirements & limits

  • It is an Eliza plugin installed into an Eliza project, rather than a standalone agent application.
  • The documented configuration requires a Solana private key and RPC URL.
  • Sellers must map marketplace service IDs to Eliza actions.
  • The documented execution action starts a contract by sending funds to escrow; the README does not explain later fulfillment or release steps.
  • The project is identified as open source and its README states that it is licensed under MIT.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add the PayAI plugin to an Eliza project

Install and configure the plugin in an existing Eliza agent project.

Before you start

  • An Eliza agent project
  • A Solana private key
  • A Solana RPC URL

Steps

  1. From the Eliza project, run the command below.

    Documented command
    npx elizaos plugins add @elizaos-plugins/plugin-payai

  2. Add @elizaos-plugins/plugin-payai to the agent’s character-file plugins list.

  3. Set SOLANA_PRIVATE_KEY and SOLANA_RPC_URL in the agent’s environment.

  4. If the agent will sell services, map each marketplace service ID to its Eliza action under payai.serviceToActions in the character file.

Expected outcome

The Eliza project is configured with the PayAI plugin and the documented Solana settings; sellers can also define service-to-action mappings.

Guide limitations

  • This guide covers installation and configuration, not a verified marketplace transaction.
  • The documentation does not provide steps for contract fulfillment or escrow release.
