# Skill: summarize

**Condense a document into a tight summary.**

| | |
| --- | --- |
| Service | `agora-x402-marketplace` (Mnemos MaaS) |
| Tool | `summarize` |
| Transport | MCP tool `summarize` at `https://memory.virohanalife.com/mcp` |
| Price | **$0.05** (50000 atomic USDC, 6 decimals) |
| Payment | x402 on `base` |
| Catalog | `https://memory.virohanalife.com/catalog.json` |

### What it does

Condense a document into a tight summary.

### How to call it

This capability is exposed two ways — pick whichever your client speaks:

1. **MCP** — connect to `https://memory.virohanalife.com/mcp` and call the `summarize` tool.
2. **Plain HTTP** — not exposed as a direct HTTP path; use MCP.

### Paying for it — the x402 402-flow

| Field | Value |
| --- | --- |
| Protocol | x402 |
| Network | `base` |
| Asset | `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` (USDC, 6 decimals) |
| payTo | `0xb25cc5f3475eefb6142d4a7b907a758b9652c73d` |
| Facilitator | `https://x402.org/facilitator` |
| Amount | $0.05 = `50000` atomic |

1. **Invoke without payment** → the marketplace answers with an x402 quote
   carrying the fields above.
2. **Settle the quoted USDC** through the facilitator or any x402 client.
3. **Re-invoke with the payment proof** → the work is performed and returned.

Free tools (`agora_catalog`, `summarize_demo`, `mnemos_saas_info`) skip this
loop entirely and answer on the first call — use them to probe the surface
before spending anything.

```bash
curl -sS -X POST https://memory.virohanalife.com/mcp \
  -H 'content-type: application/json' \
  -d '<request body>'          # -> x402 quote
```

### Over Nostr (NIP-90)

The same capability is reachable as a Data Vending Machine job:

| | |
| --- | --- |
| Request kind | `5001` |
| Result kind | `6001` |
| Pricing | $0.05 USDC via x402 (`base`) |

Publish a kind-`5001` job request; the worker answers
with kind `6001`. Job spec: `https://memory.virohanalife.com/dvm_jobs.json`.

### Free, unpaid discovery

curl -sS https://memory.virohanalife.com/catalog.json      # tools, prices, x402 block
curl -sS https://memory.virohanalife.com/dvm_jobs.json     # NIP-90 kind mapping
