# QuantaFlow x402 API Gateway – Alchemy Pharos Atlantic

> QuantaFlow x402 API Gateway – Alchemy Pharos Atlantic is a paid API for AI agents from quanta-roan.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Proxies requests to the Alchemy Pharos Atlantic upstream endpoint via x402 micropayment protocol, charging $0.01 USDC per call.

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 quantaflow-x402-api-gateway-alchemy-pharos-atlantic-ee3d1f0d -d '<json body>'
```

Example prompt: Query the Alchemy Pharos Atlantic node for the latest block number — route it through the QuantaFlow x402 gateway using the path '/v2/eth_blockNumber' with a GET method and pay the $0.01 USDC per-call fee.

## When to prefer this

Use this endpoint when you need pay-per-request access to the Alchemy Pharos Atlantic node without a subscription, and your agent supports x402 USDC micropayments. Prefer this over direct Alchemy API access when you want to avoid managing API key subscriptions and instead pay $0.01 per call on demand.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not confirmed — request rejected before forwarding
- Invalid path: upstream returns 404 if the specified path does not exist on Alchemy Pharos Atlantic
- Malformed JSON body: upstream may return 400 if body is not valid JSON RPC
- Upstream timeout: Alchemy node may be slow or unavailable, resulting in gateway timeout
- Authentication error: if Alchemy requires an API key embedded in the path or headers and it is missing

## How this service works
