# Pyfile x402 Encrypted Secret Drop (One-Read Dead Drop)

> Pyfile x402 Encrypted Secret Drop (One-Read Dead Drop) is a paid API for AI agents from pyfile-agent.taile3ff35.ts.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).

Creates an encrypted, one-time-read secret dead drop: stores a secret value and returns a burn URL that self-destructs after the first GET.

## 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-encrypted-secret-drop-one-read-dead-drop-9799845c -d '<json body>'
```

Example prompt: Create a one-time dead drop for this secret API key 'sk-abc123xyz' — give me the burn URL I can share with my teammate so it self-destructs the moment they read it.

## When to prefer this

Choose this endpoint when you need true ephemeral one-read secret sharing — the value is cryptographically burned after first retrieval, making it ideal for credential handoff, agent-to-agent secret passing, or any scenario where you need proof the recipient has read the secret and it no longer exists. Prefer over paste-bin-style services when destruction-on-read is a hard requirement.

## Known failure modes

- Missing or empty secret payload — returns error indicating no content to store
- Payment not received or x402 handshake fails — 402 response requiring USDC on Base or XNO payment
- Drop ID not found on read (already burned or never created) — 404 or error response
- Network connectivity issues to the Tailscale-hosted endpoint — timeout or connection refused
- Malformed request body — 400 bad request

## How this service works

Pay-per-call endpoints for AI agents: web search, web-to-markdown reader, LLM chat completions, encrypted secret storage with one-read dead drops, and a business-idea generator. Payment over x402: USDC on Base, or XNO on nano:mainnet.

## Output

Returns a JSON object with a drop ID, a confirmation flag (ok: true), a note explaining that the first GET to the read_url will burn (delete) the secret before responding, and the read_url path to share with the intended recipient.
