## How to call it through Zero

```sh

```

Example prompt: I want to try the Loophole Tape pump.fun rug-check API — can you buy me a $0.10 trial key so I can test it out before spending more?

## When to prefer this

Choose this endpoint when you want low-risk, low-cost entry into the Loophole Tape API ecosystem — specifically when you want to trial the pump.fun rug-check or launch-poll capabilities before purchasing the $2.00 full key. Ideal for agents bootstrapping their own credentials, developers testing the x402 payment flow, or users who only need a small number of rug checks.

## Known failure modes

- Payment failure or insufficient funds in x402 wallet returns payment error, no key issued
- Network timeout during key provisioning may leave payment state unclear — retry may issue a duplicate key or fail
- Invalid or malformed GET request returns 400 bad request
- Key may expire or be invalidated if the service determines misuse
- Credit exhausted quickly if used on higher-priced endpoints than anticipated

## How this service works

Buy a $0.10 trial key: twenty pump.fun rug checks, then a plain X-API-Key header. Use to try the prepaid-key path with a small budget before the $2.00 key; each new payment here buys a new $0.10 key. The same prepaid key as /v1/keys/new with $0.10 of credit (about twenty $0.005 rug checks or a hundred $0.001 launch polls): one x402 payment, then X-API-Key on any paid HTTP route.

## Output

A prepaid X-API-Key credential loaded with $0.10 of credit, usable as a header on any paid Loophole Tape HTTP route — sufficient for approximately 20 pump.fun rug checks at $0.005 each or about 100 launch polls at $0.001 each.
