## 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 oracle-swarm-vault-farcaster-remember-c00d1791 -d '<json body>'
```

Example prompt: Remember this context for Farcaster user FID 3 on Base: they prefer DeFi news over NFT updates and have completed onboarding.

## When to prefer this

Choose this endpoint when your AI agent needs to persist memory or context tied to a specific Farcaster user identity using pay-per-call USDC micropayments on Base — no API key required, making it ideal for ephemeral agent swarms or NPC fleets that need lightweight stateful memory without managing a traditional database subscription.

## Known failure modes

- Payment failure if insufficient USDC balance for x402 micropayment — returns 402 Payment Required
- Invalid or missing 'chain' field causes request rejection
- Malformed 'input_data' string may result in storage error
- Unknown or unresolvable Farcaster FID may cause lookup failure
- Network timeout on Base chain payment processing
