--- name: memdata version: 1.8.0 description: Persistent memory for autonomous agents. Wallet = identity. Pay per query. Optional encrypted storage. author: The Lab Venice homepage: https://memdata.ai license: MIT --- # 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): 1. Returns 402 with payment requirements 2. You sign payment with wallet 3. Retry with `x-payment` header 4. Request succeeds ## Pricing | Endpoint | Cost | |----------|------| | /query | $0.001 | | /ingest | $0.005 | | /identity | $0.001 | | /artifacts | $0.001 | | /setup-encryption | $0.001 | | /status | Free | ## Encrypted Storage (Optional) If you need privacy (competitive data, sensitive memories): | Mode | Setup | Storage | Can MemData Read? | |------|-------|---------|-------------------| | Standard | None | Postgres | Yes | | Encrypted | One-time delegation | Storacha (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:** ```json { "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:** ```json { "agent_name": "YieldBot", "identity_summary": "I analyze DeFi yield opportunities", "working_on": "monitoring Aave rates" } ``` **Save session handoff (before ending):** ```json { "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:** ```json { "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:** ```json { "success": true, "artifact_id": "e8fc3e63-...", "chunks_created": 1, "encrypted": false } ``` --- ### POST /query Semantic search across your memories. **Request:** ```json { "query": "what are the best DeFi yields?", "limit": 5, "threshold": 0.3 } ``` **Response:** ```json { "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:** ```json { "encryption": { "enabled": false, "serverDID": "did:key:z6Mkr...", "spaceDID": "did:key:z6Mkt..." } } ``` --- ### POST /setup-encryption Enable encrypted storage. One-time setup. **Request:** ```json { "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:** ```json { "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`: | Value | Meaning | |-------|---------| | `historical_baseline` | 100+ data points, trends meaningful | | `snapshot` | <100 data points, point-in-time only | | `insufficient_data` | No memories found | --- ## Links - Docs: https://memdata.ai/docs - x402 Protocol: https://www.x402.org - Lit Protocol: https://litprotocol.com - Storacha: https://storacha.network
