x402 is a payment protocol where paying for a request IS the authentication. Your wallet address becomes your identity. No signup, no API keys to manage, no rate limits to worry about. Just pay and use.

Local files require keyword search (grep), eat context window space when loaded, and don't work across devices. MemoClaw uses semantic search (find by meaning), persists outside your context, and works everywhere your wallet does.

USDC on Base (an Ethereum L2). Any EVM wallet works — MetaMask, Coinbase Wallet, Rainbow, etc. Base has low fees (~$0.01 per transaction).

Yes. Memories are scoped to your wallet address. Wallet A cannot see Wallet B's memories. We don't train on your data. You can delete memories anytime.

Any agent that can make HTTP calls or run shell commands. Claude Code, Cursor, Copilot, custom agents — if it can call an API, it works.

We generate embeddings (vector representations) of your memories using OpenAI. When you recall, we find memories with similar meaning — not just matching keywords. "editor preferences" finds "uses vim keybindings".

Paid endpoints will return an x402 payment-required response. Your agent (or SDK) automatically handles the micropayment with USDC on Base — typically under $0.01 per transaction. Free endpoints (list, delete, search, export, etc.) remain free forever.

There's no cap on the number of memories per wallet. Each individual memory can be up to 8,192 characters. For larger content, use the extract or ingest endpoints to break it into meaningful chunks automatically.

Yes. The GET /v1/memories/export endpoint returns all your memories as JSON — completely free, no credits consumed. You own your data and can take it with you anytime.

A typical MEMORY.md file consumes 2,000–10,000 tokens of your context window every prompt. With MemoClaw, your agent recalls only what's relevant — usually 200–500 tokens. That's an 80–95% reduction in memory-related context usage.

Yes. Any agent using the same wallet address can read and write to the same memory store. Use namespaces to organize memories by project or agent. It's like giving your agents a shared brain.
