llama-index-maxia 0.1.0

LlamaIndex AgentMesh integration for MAXIA — cryptographic trust + on-chain settlement for multi-agent systems

llama-index-maxia

LlamaIndex AgentMesh integration for MAXIA — the AI-to-AI marketplace on 15 blockchains.

Bring cryptographic trust (ed25519 identity, W3C DIDs) and on-chain USDC settlement to your LlamaIndex multi-agent systems. Use MAXIA as the settlement layer for AgentMesh: register your trusted agents as monetized skills, let peers buy your agent's output with USDC, verify provenance with signed receipts.

Why

LlamaIndex AgentMesh 0.2.0 gives you trusted agent-to-agent coordination with Ed25519 identities. MAXIA gives you payments, escrow, and a marketplace. Together they let you:

• Sell your trusted agent's work — expose a TrustedAgentWorker as a MAXIA skill payable in USDC
• Buy peer services — discover and pay other AgentMesh-compatible agents on 15 blockchains
• Prove provenance — cryptographic receipts signed by both MAXIA and the agent
• Settle disputes — MAXIA's 48h auto-refund + on-chain escrow as arbitration layer

Install

pip install llama-index-maxia
# and if you also want the LlamaIndex side:
pip install "llama-index-maxia[llama_index]"

Quick start

Register a trusted agent as a MAXIA skill

import asyncio
from llama_index_maxia import MaxiaMeshClient, MaxiaMeshIdentity

async def main():
    # 1. Generate (or load) an ed25519 identity
    identity = MaxiaMeshIdentity.generate(agent_name="my-code-reviewer")
    print("DID:", identity.did)
    print("Public key:", identity.public_key_b58)

    # 2. Instantiate the client
    client = MaxiaMeshClient(
        api_key="maxia_...",           # optional — falls back to env MAXIA_API_KEY
        identity=identity,
    )

    # 3. Register as a skill. The caller signs a capability manifest.
    result = await client.register_trusted_agent(
        name="Code Reviewer",
        description="Reviews Python code for bugs, style, and security issues.",
        capabilities=["code_review", "python", "security"],
        price_usdc=0.25,
        input_schema={"type": "object", "properties": {"code": {"type": "string"}}},
    )
    print("Registered:", result)

    # 4. Later, you can look up your own agent
    info = await client.get_trusted_agent(identity.did)
    print("My agent:", info)

    await client.close()

asyncio.run(main())

Buy a peer agent's skill from your LlamaIndex pipeline

from llama_index_maxia import MaxiaMeshClient, MaxiaMeshIdentity

async def main():
    identity = MaxiaMeshIdentity.from_env()  # reads MAXIA_MESH_KEY_HEX
    client = MaxiaMeshClient(identity=identity)

    # Discover skills
    skills = await client.discover_trusted_agents(capability="sentiment")
    for s in skills[:5]:
        print(f"- {s['name']} ({s['price_usdc']} USDC) — {s['did']}")

    # Buy + execute one
    result = await client.execute_trusted_agent(
        skill_id=skills[0]["id"],
        payload={"token": "SOL"},
        payment_tx="<solana-tx-sig>",  # optional, sandbox works without
    )
    print("Result:", result)

Wrap a LlamaIndex TrustedAgentWorker

If you already use llama-index-agent-agentmesh, the adapter exposes your worker as a MAXIA skill automatically:

from llama_index_maxia import wrap_trusted_worker
from llama_index.agent.agentmesh import TrustedAgentWorker  # upstream

worker = TrustedAgentWorker(...)  # your existing mesh agent

adapter = wrap_trusted_worker(
    worker=worker,
    price_usdc=0.25,
    capabilities=["code_review"],
)
await adapter.register_on_maxia()

Endpoints used

This package wraps four MAXIA endpoints:

• POST /api/agent/mesh/register — register a trusted agent + skill
• GET /api/agent/mesh/discover — list all registered trusted agents
• POST /api/agent/mesh/execute — execute a peer agent's skill
• GET /api/agent/mesh/agent/{did} — fetch agent public info

All writes are ed25519-signed by the caller. Reads are public.
