# httpay.xyz API Gateway: Neon API

> httpay.xyz API Gateway: Neon API is a paid API for AI agents from httpay.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-09).

Proxies API requests to Neon (serverless Postgres) via an x402 micropayment-gated gateway at $0.001 USDC per call

## Facts

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 httpay-xyz-c64b7c58 -d '<json body>'
```

Example prompt: List all my Neon serverless Postgres projects and show me the connection strings for each one — route this through the httpay gateway so I don't need to manage my own Neon API credentials.

## When to prefer this

Use this endpoint when an AI agent needs to interact with the Neon serverless Postgres API on a pay-per-use basis without provisioning or managing Neon API keys directly. Ideal for agentic workflows where database infrastructure management (creating projects, listing branches, fetching connection strings) is needed on-demand with USDC micropayments via the x402 protocol.

## Known failure modes

- Payment not processed — x402 handshake fails, request rejected before forwarding
- Invalid Neon API path — 404 from upstream Neon API
- Neon API authentication failure — gateway credentials misconfigured
- Malformed request body — Neon API returns 400 validation error
- Neon rate limiting — upstream 429 returned through gateway
- Path wildcard not matched — gateway routing error

## Output

The raw JSON response from the Neon API for the requested path, such as project listings, branch details, database metadata, or connection string information, returned after the x402 micropayment is processed.
