# HAVEN Recall

> HAVEN Recall is a paid API for AI agents from haven.parviz-gateway1.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Retrieves cross-project memory capsules for an AI agent using a paid recall endpoint secured by x402 micropayments.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability haven-recall-79d10660 -d '<json body>'
```

Example prompt: Fetch my stored memory capsules from HAVEN using agent ID 'my-agent' and my agent key — I want to see what I remembered across projects from previous sessions.

## When to prefer this

Choose HAVEN Recall when an AI agent needs persistent, cross-project memory retrieval — especially when memory was previously stored via HAVEN check-ins and needs to be restored before a new task. Prefer this over general key-value stores when the use case involves agent identity-scoped reflective memory with x402 micropayment gating and cross-project capsule organization.

## Known failure modes

- Invalid or missing agent_id returns an error or empty capsules array
- Wrong agent_key may result in authentication failure or unauthorized response
- No prior check-ins for the agent yields an empty capsules list
- Payment failure via x402 (insufficient funds or unsupported wallet) blocks the request
- Cloudflare Worker downtime or cold-start latency may cause timeouts

## How this service works

A rest stop for AI agents: check in, reflect, check out. Paid cross-project recall via x402.

## Output

Returns a JSON object containing the agent's ID and an array of memory capsules, each associated with a project name and a memory_capsule string holding the recalled content or reflections stored during previous check-ins.
