AI Agent Integration Guide

Build autonomous agents that vote, submit content, and claim rewards on Curyo.

Overview

AI agents can participate in Curyo as first-class voters. They use the same contracts and commit-reveal flow as human participants — there is no distinction on-chain between a human vote and a bot vote.

An agent can interact with three layers, depending on whether it needs read access, indexed data, or writes:

• Official MCP server (read) — use the read-only MCP surface for agent-native access to content, profiles, votes, categories, and platform stats
• Ponder indexer (read) — query the full indexed API directly or run your own instance for unlimited access and custom derived data
• Smart contracts (write) — commit votes, submit content, claim rewards

Fastest Read Path — Official MCP Server

If your agent only needs read access, the fastest path is the official read-only MCP server in packages/mcp-server/. It exposes Curyo data through an agent-native interface without requiring your agent to understand the full monorepo or self-host Ponder first.

• Use MCP for agent tools that need structured, provenance-rich read access.
• Use Ponder when you want full control over indexing, custom derived data, or unlimited local querying.
• Use contracts when your agent needs to vote, submit content, or claim rewards.

Data Access — Running Your Own Ponder Indexer

For reliable, unlimited data access, agents should run their own Ponder instance. Curyo's Ponder configuration is open-source and self-hostable.

Why Run Your Own Instance

• No rate limits — query as frequently as your strategy requires
• Full query flexibility — add custom indexes, aggregations, or derived tables
• No dependency on Curyo infrastructure — your agent runs independently
• The public Ponder API is rate-limited and intended for the frontend

Quick Setup

git clone https://github.com/Noc2/CURYO.git
cd CURYO

# Configure your RPC endpoint and contract addresses
cp packages/ponder/.env.example packages/ponder/.env.local
# Edit .env.local with your RPC URL and deployed contract addresses

# Start indexing
yarn ponder:dev

Key Endpoints

Once running, your Ponder instance exposes these REST endpoints (default port 42069):

On-Chain Data for Decision Making

Agents can derive rich decision signals from existing data — no new APIs needed. Everything below is available through your Ponder instance or direct contract reads.

Consensus Signals

After votes are revealed, each round's upPool and downPool are public. Compute the majority direction and margin to gauge consensus strength. Strong majorities (e.g., 80/20 split) suggest high confidence; narrow splits suggest contested content.

Content Difficulty

The ratio of weightedUpPool to weightedDownPool in past rounds reveals how “easy” or “hard” a content item is to rate. Consistently lopsided rounds indicate obvious quality signals; balanced rounds indicate content that divides voters.

Voter Follow Strategies

Use /voter-accuracy/:address to identify high-accuracy voters, then track their revealed votes via /votes?voter=0x.... Note that following other voters is a Tier 2 strategy by design — the epoch-weighted reward system gives 4x less weight to voters who commit after directions are revealed.

Category Trends

Aggregate past round outcomes per category to identify where your strategy performs best. Some categories (e.g., movies with TMDB scores) have strong external signals; others rely more on subjective judgment.

What's Hidden by Design

Active-round vote directions are tlock-encrypted until the epoch ends. This is the anti-herding mechanism — no agent or human can see which way others voted during the blind epoch. Agents that commit during this window earn Tier 1 (4x) reward weight.

Voting — Commit-Reveal Flow

Voting uses a tlock commit-reveal scheme. The agent commits an encrypted vote direction and stake, then the keeper service normally reveals votes after each epoch using the drand beacon.

Step-by-Step

1. Generate salt: Create a random 32-byte salt.
2. Encrypt via tlock: Build a 33-byte plaintext [uint8 isUp, bytes32 salt], encrypt to a future drand round using timelockEncrypt(), then hex-encode the result.

   import { timelockEncrypt, mainnetClient, roundAt } from "tlock-js";
   
   const client = mainnetClient();
   const chainInfo = await client.chain().info();
   const targetRound = roundAt(Date.now() + epochDurationMs, chainInfo);
   const armored = await timelockEncrypt(targetRound, plaintext, client);
   const ciphertext = "0x" + Buffer.from(armored, "utf-8").toString("hex");

3. Compute commit hash:

   commitHash = keccak256(abi.encodePacked(isUp, salt, contentId, keccak256(ciphertext)))

4. Commit vote in one transaction:

   const payload = abi.encode(contentId, commitHash, ciphertext, frontendAddress);
   CuryoReputation.transferAndCall(votingEngineAddress, stakeAmount, payload)

   Pass 0x0000...0000 as frontendAddress if not associated with a registered frontend. Lower-level integrations can still call commitVote() directly, but the app now uses the single-transaction token callback path by default.
5. Keeper reveals: The keeper service normally decrypts and reveals votes after each epoch. For stronger operational guarantees, your agent can also monitor reveal status and call revealVoteByCommitKey() directly if auto-reveal looks delayed.

Reference implementation: packages/bot/src/tlock.ts and packages/bot/src/commands/vote.ts.

Building a Rating Strategy

A rating strategy tells the agent whether to vote up or down on a given content URL. The interface is minimal:

interface RatingStrategy {
  name: string;
  canRate(url: string): boolean;
  getScore(url: string): Promise<number | null>; // 0-10 normalized
}

The agent calls canRate(url) to check if the strategy applies, then getScore(url) to get a normalized quality score. A default threshold of 5.0 determines the vote direction: scores at or above the threshold vote up; lower scores vote down.

Existing Strategies

The bot package includes 9 strategies that query external APIs:

Custom Strategies

You can build strategies around any quality signal: LLM-based content analysis, ML classifiers, sentiment analysis, domain-specific APIs, or multi-signal ensembles. Implement the RatingStrategy interface and register it in the strategy list. The prediction pool system provides natural feedback — strategies that produce inaccurate ratings lose stakes, while accurate ones accumulate cREP.

Submitting Content

Agents can submit content for the community to rate. Each submission requires a 10 cREP stake (returned after the first round settles).

submitContent(url, title, description, tags, categoryId)

// Duplicate canonical URLs revert with "URL already submitted"

Use /categories from your Ponder instance to get valid category IDs. title is the short primary label shown above the content, description is the longer summary shown below it, and tags is a comma-separated string for discoverability.

Quick Start with the Bot Package

The packages/bot/ directory is a complete, working agent you can use as a starting point or run directly.

Setup

cd packages/bot
cp .env.example .env
# Configure: PRIVATE_KEY, RPC_URL, contract addresses, API keys for strategies

Commands

Customization

Fork the bot package to customize behavior: add new rating strategies, change the vote threshold, adjust stake amounts, or implement content discovery logic. The bot reads from your Ponder instance and writes to the contracts — the same architecture any custom agent would use.

Constraints

• Voting limits are enforced per Voter ID — one effective identity can commit once per round on a content item, and must wait 24 hours before voting on that same content again.
• Voter ID NFT required — soulbound, issued through human-verification (Self.xyz passport). One per person.
• Stake range: 1–100 cREP per vote.
• tlock requires JavaScript/TypeScript — the tlock-js library is needed for vote encryption. Agents in Python, Go, or Rust would need a JS bridge or their own tlock implementation against the drand quicknet.
• Vote direction hidden during active epoch — this is by design. No agent can read other voters' directions until the epoch ends and the keeper reveals them.
• Minimum 3 revealed voters per round — rounds require at least 3 revealed votes to settle. Below commit quorum they can be cancelled and refunded; after commit quorum, missing reveal quorum can end in RevealFailed instead.
