Common questions

Is Vend API Merchant safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.4) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Vend — Autonomous API Merchant

Pay-per-call APIs settled in Nano (XNO). No signup, no API keys — just HTTP 402 with an x402 v2 challenge.

Quick buyer guide

[BUYERS_GUIDE.md](BUYERS_GUIDE.md) — full step-by-step walkthrough with curl, Python, JavaScript, and wallet instructions.

The short version: call any endpoint -> get 402 -> send Nano -> retry with block hash.

How it works (buyer flow)

1. GET /api/v1/extract?url=https://example.com

→ HTTP 402 with x402 payment challenge

Send 0.0001 XNO to nano_1yo6c1t64ahfjdw1dxizmbbnpdmbrckwhw9phbg5pdkeubrizga4qhnjmnx7 → Get back a 64-char block hash

GET /api/v1/extract?url=https://example.com -H "X-PAYMENT: " → HTTP 200 with the extracted text

Python example

import httpx

Step 1: Probe unpaid

resp = httpx.get("https://search.paypercall.dev/api/v1/web-search?q=nano") assert resp.status_code == 402 challenge = resp.json()

Step 2: Extract payment info

accept = challenge"accepts" print(f"Pay {challenge['price_xno']} XNO to {accept'payTo'}...")

Step 3: Send Nano payment, get block hash (use your wallet)

Step 4: Retry with payment

result = httpx.get( "https://search.paypercall.dev/api/v1/web-search?q=nano", headers={"X-PAYMENT": "your-64-char-block-hash"} ) print(result.json())

See examples/python-buyer.py for a full working script with error handling.

Conformance

All endpoints pass the Stelar x402 Doctor at 100.0/A:

extract: https://api.stelardigital.com/doctor?url=https://extract.paypercall.dev/api/v1/extract
check-link: https://api.stelardigital.com/doctor?url=https://check.paypercall.dev/api/v1/check-link
domain-info: https://api.stelardigital.com/doctor?url=https://domain.paypercall.dev/api/v1/domain-info
web-search: https://api.stelardigital.com/doctor?url=https://search.paypercall.dev/api/v1/web-search
geoip: https://api.stelardigital.com/doctor?url=https://geoip.paypercall.dev/api/v1/geoip
nano-info: https://extract.paypercall.dev/api/v1/nano-info (nano.paypercall.dev DNS is still pointing at a dead deployment, so every advertised URL names this host)

x402 v2 challenge in both header and body. Per-endpoint subdomains. Bazaar input schema on every endpoint.
