# Pyfile x402 Pass Purchase API

> Pyfile x402 Pass Purchase API is a paid API for AI agents from pyfile-agent.taile3ff35.ts.net:10000, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-20).

Purchase a time-window + quota pass for a specific scope, returning a reusable token to skip per-call payments on covered routes until expiry or quota exhaustion.

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-pass-purchase-api-f34ce34d -d '<json body>'
```

Example prompt: Buy me a 7-day secret scope pass on the Pyfile toolkit so I can make multiple API calls without paying each time — use the secret-7d scope.

## When to prefer this

Choose this endpoint when you plan to make multiple calls to Pyfile toolkit routes within a fixed time window and want to avoid per-call x402 micro-payments. It is especially cost-effective for high-frequency or batch usage patterns. Prefer the matching scope (web-24h for short bursts, secret-7d for a week of secret-route access, ideas-30d for sustained month-long usage).

## Known failure modes

- Invalid or unrecognized scope value returns an error — must be exactly web-24h, secret-7d, or ideas-30d
- Payment failure (insufficient USDC balance or x402 protocol error) prevents pass issuance
- Pass already expired or quota already exhausted after purchase — token becomes invalid on covered routes
- Network timeout or server error on the Tailscale-hosted endpoint

## How this service works

Buy a time-window pass with quota. Body: {scope: web-24h|secret-7d|ideas-30d}. Returns a token to send as header X-Pass on covered routes, skipping per-call payment until the pass expires or the quota is used.

## Output

Returns a JSON object with ok (boolean), a pass token string to send as X-Pass header on covered routes, the scope, an ISO-8601 valid_until expiry timestamp, integer quota of covered calls, and an array of route paths covered by the pass.
