## 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 l402-space-universal-402-gateway-cc18084c -d '<json body>'
```

Example prompt: Forward my POST request to https://api.example.com/generate-report and pay the 402 fee automatically using my agentic wallet over x402 — just proxy it through l402.space and give me the response.

## When to prefer this

Choose this endpoint when your AI agent needs to call any 402-payment-gated API without implementing L402, x402, or Lightning payment logic from scratch. It is ideal for agentic workflows where the agent holds a compatible wallet and needs to pay-per-call across multiple upstream APIs using a single proxy URL, avoiding per-provider payment integration overhead.

## Known failure modes

- Upstream API URL is unreachable or invalid — returns a gateway error
- Insufficient wallet balance to complete the $0.01 USDC payment — returns payment failure
- Upstream API rejects the request for reasons unrelated to payment (auth, bad input) — upstream error is forwarded
- Unsupported payment rail requested — gateway cannot complete negotiation
- Malformed upstream URL in path parameter — routing error

## How this service works

Any wallet. Any paid API. Any rail. l402.space is a payment gateway that lets you pay for any 402-gated API with any agentic wallet — over L402, x402, or MPP (Lightning or Tempo). Browse live stats and grab a proxy URL for any endpoint.

## Output

The proxied HTTP response from the upstream 402-gated API, returned after l402.space has negotiated and completed the required payment on the caller's behalf. Includes whatever payload the upstream API produces (JSON, text, binary, etc.) along with payment confirmation metadata.
