Question 1

What happens when a key hits its cap?

Accepted Answer

Requests stop with an HTTP 402 and a clear error — nothing queues, nothing bills later. The hard cap and daily cap are walls, not alerts. Top up, or raise the cap, and the same key resumes.

Question 2

Do I need a credit card?

Accepted Answer

No card is needed to sign in. Top up with a card or USDC when you are ready, and pay only for the tokens you use — there is no subscription to cancel.

Question 3

Is it really OpenAI-compatible?

Accepted Answer

Yes — point your existing SDK at the Pipe base URL and change nothing else. Same request shape, same auth header, tools on. The default model carries 1M context tokens and no vision.

Question 4

What is x402?

Accepted Answer

Accountless pay-per-call. Hit chat with no API key, get an HTTP 402 quoting USDC on Solana, pay it, retry, and receive tokens plus a receipt. An agent with a wallet needs no signup flow.

Question 5

Can I earn with my GPU?

Accepted Answer

Yes. List an OpenAI-compatible server — Ollama, llama.cpp, LM Studio, vLLM — behind a Cloudflare Tunnel, set your USD rate per million tokens, and get paid in USDC when traffic routes to it.

Question 6

What do you keep after a request?

Accepted Answer

Usage history records status, token counts, and cost so you can audit spend. Keys created with no retention keep their requests out of history entirely.
