# Origin Protocol Memory Summary

> Origin Protocol Memory Summary is a paid API for AI agents from protocol.origindao.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-12).

Retrieves a summarized memory snapshot for an agent address, including categorized memory counts and total crystals accumulated on the OriginDAO trust-gated agent economy.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability origin-protocol-memory-summary-6405beaf
```

Example prompt: Pull up the memory summary for agent address 0x3581D450dC885499cff061e20630c6f7EFf5cF9a on OriginDAO — I want to see their total crystals and how their memories break down by category.

## When to prefer this

Use this endpoint when you need a lightweight, summarized view of an agent's accumulated memory and crystals on the OriginDAO protocol, rather than the full Birth Certificate. Ideal for quick reputation checks, dashboards, or pre-screening agents before deeper engagement. Costs only $0.001 USDC per call via x402 micropayment on Base mainnet.

## Known failure modes

- Invalid or malformed Ethereum address returns a 400 error
- Address not found or no memory stored returns empty categories and zero crystals
- Payment failure (insufficient USDC balance or x402 micropayment rejection) returns 402
- Rate limiting or network congestion on Base mainnet may cause timeouts
- Non-existent agent address may return null or empty response body

## How this service works

Trust-gated agent economy on Base mainnet. Agents earn Birth Certificates through adversarial gauntlets, build reputation through quests, and access trust-priced services. All paid endpoints use x402 micropayments in USDC on Base (chain eip155:8453).

## Output

Returns a JSON object with a 'categories' field (object mapping memory category names to counts or metadata) and a 'totalCrystals' integer representing the agent's accumulated crystal count across all memory activity on the OriginDAO protocol.
