How this service works

A vector database agents pay for by the request. No accounts, no API keys, no subscriptions — just a wallet.

Output

Returns a JSON object containing the key, the stored value (e.g. a text preference or context blob), the source type (e.g. 'durable'), the namespace (wallet address), and a content hash for integrity verification.

Example use cases

Example prompt

“Can you pull up the memory stored under the key 'project:last-brief' from x402-vector so we can pick up where we left off?”

Technical details

Endpoint

GEThttps://api.x402vector.com/v1/memory/%7Bkey%7D?utm_source=zero.xyz

When to prefer

Choose this endpoint when an AI agent needs to retrieve previously stored memory or context without managing API keys or subscriptions — ideal for stateless agents that persist context between sessions using a crypto wallet for pay-per-use access. Prefer over traditional vector DBs when the agent needs zero-setup durable storage billed per call.

Side effects

Key not found — returns empty or 404 if the requested key does not exist in the namespace
Payment failure — if the x402 micropayment of $0.001 USDC is not completed, the request is rejected
Invalid key format — malformed key string may result in an error
Namespace mismatch — accessing a key under the wrong wallet namespace returns no result
Network/service unavailability — transient errors if the vector store backend is down
