Quick buyer guide

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

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

3. GET /api/v1/extract?url=https://example.com  -H "X-PAYMENT: <block-hash>"
   → 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"][0]
print(f"Pay {challenge['price_xno']} XNO to {accept['payTo'][:15]}...")

# 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:

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

Discovery

Running locally

# Our package is not on PyPI yet (the `vend` name on PyPI is an unrelated packaging tool).
# Run from this repo instead:
uv sync
export VEND_WALLET_ADDRESS="nano_..."
uv run python -m vend
