## How to call it through Zero

```sh
zero fetch --capability loophole-tape-trial-api-key-cbe41275
```

Example prompt: Get me a loophole tape trial API key so I can start running pump.fun token risk checks — pay the $0.10 USDC via x402 and give me the key and my starting balance.

## When to prefer this

Use this endpoint when you need to bootstrap access to the Loophole Tape API for the first time with minimal upfront cost. It is the right choice for trial use, agent onboarding, or testing pump.fun/PumpSwap risk check capabilities before purchasing larger credit bundles. Prefer this over /v1/keys/new if you want the lowest-cost entry point.

## Known failure modes

- Payment not settled — key status remains pending, not active
- x402 payment rejected or insufficient funds — no key issued
- Network error during payment flow — may require retry
- Duplicate payment attempts may result in multiple keys being created

## How this service works

Buy a $0.10 trial key: twenty compact checks, then a plain X-API-Key header. The same prepaid key as /v1/keys/new with $0.10 of credit (about twenty $0.005 checks or a hundred $0.001 polls): one x402 

## Output

Returns a JSON object with an API key string (lt_... format), usage instructions including the X-API-Key header format, a list of covered routes, the key status (active_on_settlement), and starting credit balance in USD (~$0.10 = ~20 checks at $0.005 each or ~100 polls at $0.001 each).
