OpenClaw BaseCred SDK

Check human reputation via Ethos Network, Talent Protocol, and Farcaster using the neutral basecred-sdk. Fetches composable reputation data without judgment - raw scores, levels, and signals for identity verification and trust assessment. Use when you need to check someone's onchain credibility, builder/creator scores, or Farcaster quality metrics.

basecred-sdk-skill

OpenClaw skill for checking human reputation via Ethos Network, Talent Protocol, and Farcaster using the neutral basecred-sdk.

Overview

This skill provides a CLI interface to the @basecred/sdk for fetching neutral, composable reputation data from multiple web3 identity providers:

• Ethos Network - Social credibility (vouches, reviews, score)
• Talent Protocol - Builder and creator scores
• Farcaster (Neynar) - Account quality metrics

The SDK is designed to make reputation data observable without turning it into judgment. It returns raw scores, levels, and signals—no rankings, no percentiles, no trust verdicts.

Security

This skill uses secure, hardcoded credential loading — see SECURITY.md for full audit details.

TL;DR:

• ✅ Credentials loaded from ~/.openclaw/.env (hardcoded path, no directory traversal)
• ✅ Upstream package @basecred/sdk@0.6.2 audited and clean (MIT licensed, minimal deps)
• ✅ No secrets logged or written to disk
• ✅ Read-only API access (public reputation data)

Prerequisites

Required

• Node.js 18+
• OpenClaw runtime

Optional API Keys

Environment variables (in ~/.openclaw/.env):

# Optional: Enables Talent Protocol builder/creator scores
TALENT_API_KEY=your_talent_api_key

# Optional: Enables Farcaster quality scores
NEYNAR_API_KEY=your_neynar_api_key

Notes:

• Ethos Network requires no API key
• Without TALENT_API_KEY, builder/creator scores will be unavailable
• Without NEYNAR_API_KEY, Farcaster scores will be unavailable
• The skill works with partial data (graceful degradation)

Full Profile Format

See @basecred/sdk documentation for complete schema.

Data Sources

Ethos Network

What it provides:

• Social credibility score (0-2800)
• Vouches received (trust endorsements)
• Reviews (positive/neutral/negative)
• Semantic credibility level (Untrusted → Renowned)

No API key required.

Talent Protocol

What it provides:

• Builder Score - Technical/development credibility (0-250+)
• Creator Score - Content/creative credibility (0-250+)
• Rank positions (when available)
• Semantic levels (Novice → Master / Emerging → Elite)

Requires: TALENT_API_KEY

Farcaster (Neynar)

What it provides:

• Account quality score (0-1)
• Quality threshold pass/fail (default: 0.5)

Requires: NEYNAR_API_KEY

Availability States

Each data source returns exactly one state:

State	Meaning
available	Profile exists, data fetched successfully
not_found	No profile exists for this address
error	API error or failure

The skill never crashes on missing data. Partial responses are valid and useful.

Semantic Levels

The SDK derives human-readable levels from raw scores:

Ethos Credibility Levels:

• 0-799: Untrusted
• 800-1199: Questionable
• 1200-1399: Neutral
• 1400-1599: Known
• 1600-1799: Established
• 1800-1999: Reputable
• 2000-2199: Exemplary
• 2200-2399: Distinguished
• 2400-2599: Revered
• 2600-2800: Renowned

Talent Builder Levels:

• 0-39: Novice
• 40-79: Apprentice
• 80-119: Practitioner
• 120-169: Advanced
• 170-249: Expert
• 250+: Master

Talent Creator Levels:

• 0-39: Emerging
• 40-79: Growing
• 80-119: Established
• 120-169: Accomplished
• 170-249: Prominent
• 250+: Elite

Recency Buckets

Data freshness indicator:

Bucket	Condition
recent	Updated within 30 days
stale	Updated 31-90 days ago
dormant	Updated more than 90 days ago

Testing

Run the test suite with known addresses:

npm test

This tests:

• Vitalik Buterin (vitalik.eth)
• Mr. Tee (main wallet)

Integration with Other Skills

Import the library in your own scripts:

import { checkReputation, getSummary, formatHuman } from './lib/basecred.mjs';

const result = await checkReputation('0x...');
const summary = getSummary(result);
console.log(summary);

Error Handling

The skill uses graceful error handling:

• Invalid address → returns error object with message
• Missing API keys → warns but continues with available sources
• API failures → surfaced via availability field
• Network errors → returns error object with details

Never throws exceptions - always returns structured data.

Design Principles

This skill follows the basecred-sdk philosophy:

• Absence is explicit - Missing data is declared, never hidden
• Time matters more than score - Temporal fields enable continuity analysis
• Sources are parallel - No source is "better" than another
• Data is reported, not judged - Consumers interpret meaning

Non-Goals

This skill intentionally does NOT:

• Decide trustworthiness
• Rank users against each other
• Compare users
• Produce composite scores
• Replace human judgment

Performance

• Average query time: 1-3 seconds (depends on network + API response times)
• API calls: 1-3 concurrent requests (one per enabled source)
• No rate limiting - but respect upstream API limits

Troubleshooting

"TALENT_API_KEY not found" warning:

• Add TALENT_API_KEY=xxx to ~/.openclaw/.env
• Or accept that Talent scores will be unavailable

"NEYNAR_API_KEY not found" warning:

• Add NEYNAR_API_KEY=xxx to ~/.openclaw/.env
• Or accept that Farcaster scores will be unavailable

All sources return not_found:

• Address may not have profiles on any platform
• This is valid - absence is data

Unexpected errors:

• Check network connectivity
• Verify API keys are valid
• Check upstream API status
