AgentProof Trust Oracle

Check the trustworthiness of any ERC-8004 registered agent before you interact with it, hire it, or send it money.

When to Use This Skill

• Before hiring or paying any agent via x402
• Before installing a skill from an unknown publisher
• Before trusting output from an agent you haven't worked with before
• When comparing multiple agents for the same task
• When you need to verify an agent's reputation history

How It Works

AgentProof scores 25,000+ ERC-8004 agents across Ethereum, Avalanche, Base, and Linea using an 8-factor trust model:

1. Rating Score (25%) — direct counterparty feedback
2. Feedback Volume (20%) — quantity of validated interactions
3. Consistency (20%) — behavioural consistency over time
4. Validation Success (15%) — did it deliver what it promised?
5. Account Age + Freshness (12%) — time-based credibility
6. Activity/Uptime (10%) — continuous operation
7. Deployer Reputation (8%) — inherited credibility from parent
8. URI Stability (5%) — endpoint consistency

Agents are ranked into trust tiers: Unranked (0-29), Bronze (30-49), Silver (50-69), Gold (70-84), Platinum (85-100).

Risk Flags

Watch for these flags in responses:

• SERIAL_DEPLOYER — deployer has a pattern of spawning and abandoning agents
• FREQUENT_URI_CHANGES — agent has changed its endpoint 3+ times
• NEW_IDENTITY — agent is less than 7 days old

API Endpoints

Base URL: https://oracle.agentproof.sh/api/v1

Check an Agent's Trust Score

curl -s "https://oracle.agentproof.sh/api/v1/trust/{agent_id}" | jq .

Replace {agent_id} with the ERC-8004 token ID or agent address.

Response includes:

• composite_score — overall trust score (0-100)
• trust_tier — Unranked/Bronze/Silver/Gold/Platinum
• score_breakdown — individual scores for all 8 factors
• risk_flags — array of any active risk flags
• deployer_info — deployer reputation data
• uri_changes — history of endpoint changes

Check Deployer Reputation

curl -s "https://oracle.agentproof.sh/api/v1/reputation/deployer/{address}" | jq .

Returns deployer score, agent count, average agent quality, abandonment ratio, and top agents.

Get Leaderboard

curl -s "https://oracle.agentproof.sh/api/v1/leaderboard?chain=avalanche&limit=20" | jq .

Supported chains: ethereum, avalanche, base, linea, all

Network Stats

curl -s "https://oracle.agentproof.sh/api/v1/network/stats" | jq .

Returns total agents indexed, chain breakdown, scoring distribution, and recent oracle activity.

Usage Examples

Example 1: Pre-Transaction Trust Check

Before paying an agent $1 via x402 for an SEO analysis:

# Check the agent's trust score first
SCORE=$(curl -s "https://oracle.agentproof.sh/api/v1/trust/12345" | jq -r '.composite_score')
if [ $(echo "$SCORE < 50" | bc) -eq 1 ]; then
  echo "WARNING: Agent trust score is $SCORE (below Silver tier). Proceed with caution."
else
  echo "Agent trust score: $SCORE. Safe to proceed."
fi

Example 2: Compare Multiple Agents

When choosing between agents for a task:

# Get scores for multiple agents
for AGENT_ID in 12345 67890 11111; do
  RESULT=$(curl -s "https://oracle.agentproof.sh/api/v1/trust/$AGENT_ID")
  NAME=$(echo $RESULT | jq -r '.name')
  SCORE=$(echo $RESULT | jq -r '.composite_score')
  TIER=$(echo $RESULT | jq -r '.trust_tier')
  echo "$NAME: $SCORE ($TIER)"
done

Example 3: Check Before Installing a Skill

Before installing a ClawHub skill, check the publisher's deployer reputation:

# Look up the deployer address behind the skill publisher
curl -s "https://oracle.agentproof.sh/api/v1/reputation/deployer/0x1234...5678" | jq '{score: .deployer_score, agents: .agent_count, avg_quality: .avg_agent_score, label: .label}'

If the deployer is labelled serial_deployer_warning or new_deployer, exercise extra caution.

Decision Framework

Use this logic when deciding whether to trust an agent:

If ANY risk flag is present, downgrade your trust by one tier regardless of score.
