@krewe/elizaos-plugin

Pay-per-call AI inference for elizaOS agents. Adds four Actions backed by the krewe decentralized network on Base — text.structure, text.embed, web.scrape, and quantized SLM text.complete. Every call is paid in USDC via x402 (EIP-3009), and every result is independently re-computed by 3 miner nodes with 2-of-3 byte-equal consensus before it settles.

Status: v0.1.0 — first cut. Tested at the SDK level against the live network; the elizaOS integration has not yet been validated inside a complete agent runtime. If you dogfood this and hit issues, please open an issue or reply on the Eliza discussion.

Install

pnpm add @krewe/elizaos-plugin
# (your project should already have @elizaos/core)

Configure

Add two settings to your character / agent config:

{
  "settings": {
    // 0x-prefixed 32-byte private key. Base wallet, ≥ $0.10 USDC.
    // Use a dedicated agent burner key, not your personal wallet.
    "KREWE_AGENT_PRIVATE_KEY": "0x…",

    // Optional: defaults to the krewe production orchestrator.
    "KREWE_ORCHESTRATOR_URL": "https://krewe-orchestrator-production.up.railway.app"
  }
}

Wire into the agent

import { AgentRuntime } from "@elizaos/core";
import { kreweplugin } from "@krewe/elizaos-plugin";

const runtime = new AgentRuntime({
  character,
  plugins: [kreweplugin],
  // …
});

What it adds

| Action name | Job kind | Price | What it does | |--------------------------|-----------------|---------|-----------------------------------------------------------| | KREWE_EXTRACT_ENTITIES | text.structure | $0.005 | Extract emails / URLs / dates / numbers / phones | | KREWE_EMBED_TEXT | text.embed | $0.010 | 384-dim sentence embedding (all-MiniLM-L6-v2) | | KREWE_SCRAPE_URL | web.scrape | $0.020 | Fetch + clean a small URL payload | | KREWE_COMPLETE | text.complete | $0.050 | Quantized SLM completion (LaMini-GPT-124M) w/ consensus |

Each action's validate() checks that KREWE_AGENT_PRIVATE_KEY is set before the action becomes available to the LLM — agents without a wallet won't see the actions at all.

Cost control

Set a per-call spending cap on the client by configuring KREWE_MAX_PRICE_USDC (USDC base units) — defaults to 100000 ($0.10).

Verifiable execution

Every action's result includes paymentTxHash and replicas count. The plugin appends a short tag like (replicas=3, paid=0xabc…) to the rendered output so the user can click through to Basescan and verify the payment + consensus.

Example output from KREWE_EXTRACT_ENTITIES:

Extracted via krewe (replicas=3, paid=0xf550…2f77):
{
  "emails": ["[email protected]"],
  "urls":   ["https://krewe.world/"],
  "dates":  ["2026-06-12"]
}

Why this is different from a regular LLM provider plugin

• No API key. The agent's wallet IS the auth.
• Per-call settlement on-chain. Every call has a Basescan tx, auditable forever.
• Byte-equal consensus. For KREWE_COMPLETE, three independent operators must produce identical token streams before the result is returned — useful when a single LLM provider shouldn't be a single point of trust.
