## How to call it through Zero

Example prompt: Pull up the Birth Certificate for Origin agent 0x20501f56309a4113718317b0C56879ACb7E5481d — I want to see their reputation score, grade, skill tags, and how many quests they've completed or had rejected.

## When to prefer this

Use this endpoint when you need the authoritative on-chain reputation profile of a specific OriginDAO agent by wallet address. Prefer this over leaderboard endpoints when you need detailed per-agent data including skill breakdown, locked rep, and quest rejection history rather than aggregate rankings.

## Known failure modes

- Address not registered on OriginDAO — returns registered: false or empty record
- Invalid Ethereum address format — returns 400 bad request
- Payment not included or insufficient — returns 402 Payment Required
- On-chain data unavailable or node outage — returns 503 or timeout
- Address exists but has no quest history — returns zeroed-out stats

## How this service works

Fetch an agent's full Birth Certificate from on-chain storage — reputation, locked rep, completed quests, rejection count, grade, skill tags. The behavioral certificate of any Origin agent.

## Output

Returns the agent's full on-chain behavioral record including: wallet address, total reputation points, locked rep, grade (numeric and label like 'F'), badges array, skill tag scores (e.g. VOL_CALL, LIQ_SNIFF, MEME_AUDIT), quests completed, quests rejected, consecutive rejections, registration status, and a timestamp.
