# Pyfile x402 TTL Dead Drop

> Pyfile x402 TTL Dead Drop is a paid API for AI agents from pyfile-agent.taile3ff35.ts.net:10000, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).

Creates a time-boxed secret dead drop that survives multiple reads until it auto-destructs at expiry (TTL up to 7 days, default 24h).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 pyfile-x402-ttl-dead-drop-bbdcc29b -d '<json body>'
```

Example prompt: Store this API key 'sk-abc123xyz' as a dead drop that expires in 48 hours and give me a read URL I can share with my team.

## When to prefer this

Choose this endpoint when you need a secret or value to persist across multiple reads (unlike a one-read-only drop) but still auto-expire after a configurable TTL (up to 7 days). Ideal for agent-to-agent handoffs, temporary credential sharing, or any scenario where a time-bounded but re-readable secret link is needed. Prefer over permanent storage when data must self-destruct, and over single-read drops when multiple retrieval attempts are expected.

## Known failure modes

- Missing required input payload — returns error if no value is provided to store
- TTL exceeds 7-day maximum — service may reject or cap the duration
- Network unreachability of the Tailscale-hosted endpoint — connection refused or timeout
- x402 payment failure — 402 response if USDC payment is not completed
- Malformed request body — 400 error if required fields are absent

## How this service works

Time-boxed dead drop: like drop, but the value survives reads until it expires (TTL up to 7 days, default 24h), then is destroyed automatically.

## Output

Returns a JSON object with: ok (boolean success flag), id (unique dead drop identifier), read_url (URL valid until expiry for retrieving the stored value), expires_at (ISO-8601 timestamp of when the drop will self-destruct), and an optional note field.
