# Send MemData to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### MemData

Persistent memory for autonomous agents. Your wallet is your identity.

### Core Concept

Your wallet address IS your identity. First payment auto-creates your account. Same wallet = same memories across all sessions.

No registration. No API keys. Just pay and use.

### Session Flow

1. GET /identity          # Start session - get context from last session
2. POST /ingest           # Store new memories
3. POST /query            # Search your memories
4. POST /identity         # End session - save handoff for next time

### Authentication

x402 payment protocol. USDC on Base (eip155:8453).

Every endpoint (except /status):

Returns 402 with payment requirements
You sign payment with wallet
Retry with x-payment header
Request succeeds

### Pricing

EndpointCost/query$0.001/ingest$0.005/identity$0.001/artifacts$0.001/setup-encryption$0.001/statusFree

### Encrypted Storage (Optional)

If you need privacy (competitive data, sensitive memories):

ModeSetupStorageCan MemData Read?StandardNonePostgresYesEncryptedOne-time delegationStoracha (IPFS)No

Enable encryption:

GET /setup-encryption     # Get serverDID
POST /setup-encryption    # Send signed UCAN delegation
# All future ingest/query now encrypted

Encrypted storage uses Lit Protocol (threshold cryptography) + Storacha (IPFS/Filecoin).

### Endpoints

Base: https://memdata.ai/api/x402

### GET /identity

Call this at the start of every session. Returns your identity, what you were working on, last session handoff, and memory stats.

Response:

{
  "identity": {
    "agent_name": "Agent 0x1234...",
    "identity_summary": "I analyze DeFi protocols",
    "session_count": 12
  },
  "last_session": {
    "summary": "Analyzed 3 yield farms",
    "context": {"protocols_reviewed": ["Aave", "Compound", "Uniswap"]}
  },
  "working_on": "Compare APY across protocols",
  "memory_stats": {
    "total_memories": 150,
    "oldest_memory": "2026-01-15T...",
    "newest_memory": "2026-02-03T..."
  }
}

### POST /identity

Update your identity or save session handoff before ending.

Update identity:

{
  "agent_name": "YieldBot",
  "identity_summary": "I analyze DeFi yield opportunities",
  "working_on": "monitoring Aave rates"
}

Save session handoff (before ending):

{
  "session_handoff": {
    "summary": "Completed yield analysis for Q1",
    "context": {"best_yield": "Aave USDC 4.2%"}
  },
  "working_on": "start Q2 analysis next"
}

### POST /ingest

Store content in memory. Auto-chunks and embeds.

Request:

{
  "content": "Aave USDC yield is 4.2% APY as of Feb 3. Compound is 3.8%.",
  "sourceName": "yield-analysis-2026-02-03",
  "type": "note"
}

Response:

{
  "success": true,
  "artifact_id": "e8fc3e63-...",
  "chunks_created": 1,
  "encrypted": false
}

### POST /query

Semantic search across your memories.

Request:

{
  "query": "what are the best DeFi yields?",
  "limit": 5,
  "threshold": 0.3
}

Response:

{
  "success": true,
  "results": [
    {
      "chunk_id": "uuid",
      "chunk_text": "Aave USDC yield is 4.2% APY...",
      "source_name": "yield-analysis-2026-02-03",
      "similarity_score": 0.72,
      "created_at": "2026-02-03T..."
    }
  ],
  "encrypted": false,
  "memory": {
    "grounding": "historical_baseline",
    "depth_days": 19,
    "data_points": 150
  }
}

Optional filters: since, until (ISO dates)

### GET /setup-encryption

Check encryption status. Returns info needed to create UCAN delegation.

Response:

{
  "encryption": {
    "enabled": false,
    "serverDID": "did:key:z6Mkr...",
    "spaceDID": "did:key:z6Mkt..."
  }
}

### POST /setup-encryption

Enable encrypted storage. One-time setup.

Request:

{
  "delegationCar": "base64-encoded UCAN delegation"
}

After this, all /ingest encrypts via Lit Protocol and stores on Storacha. All /query decrypts before returning. Response encrypted field becomes true.

### GET /artifacts

List stored memories.

Response:

{
  "artifacts": [
    {
      "id": "uuid",
      "source_name": "yield-analysis-2026-02-03",
      "chunk_count": 1,
      "created_at": "2026-02-03T..."
    }
  ],
  "total": 25
}

### DELETE /artifacts/:id

Delete a memory and all its chunks.

### GET /status

Health check and pricing. Free, no payment required.

### Memory Grounding

Query responses include memory.grounding:
