OpenAPI Specification
openapi: 3.2.0
info:
title: GetApi DNSBL / Spam Blacklist API
version: 0.0.1
description: '## Authentication
All API endpoints require authentication. Include your API key in every request using **one** of the following methods:
**Option 1 — X-Api-Key header (recommended)**
```
X-Api-Key: ga_live_xxxxxxxxxxxxxxxxxxxx
```
**Option 2 — Bearer token**
```
Authorization: Bearer ga_live_xxxxxxxxxxxxxxxxxxxx
```
You can generate and manage API keys in your dashboard.
## AI & Agent Payments (x402)
Some endpoints support direct payments for AI agents via the **x402** protocol (https://www.x402.org).
No API key or account is needed. Send a normal request without key;
the server will respond with **HTTP 402** and a `PAYMENT-REQUIRED` header:
```
PAYMENT-REQUIRED:
```
This base64 string contains, among other things, `network`, `asset`, `amount`, and `payTo`.
Your agent signs an EIP-3009 *transferWithAuthorization* for the specified `amount` of USDC to that `payTo` address,
encodes the signature as base64, and resubmits the request with:
```
PAYMENT-SIGNATURE:
```
The server verifies the signature via a facilitator, provides the data, and settles the payment on-chain.
The success response includes a `PAYMENT-RESPONSE` header containing the transaction information.
A one-time `nonce` prevents replay attacks. Payments are made in USDC on **Base**;
the price is determined by the `credit_cost` of the endpoint.'

x-guidance: 'GetAPI.nl is een Nederlandse API-platform voor lookups en validaties (postcode,
adres, kenteken, BTW, e-mail, KVK, IBAN, energiemaatwerk, overheidsdata). Elke
endpoint accepteert een API key via de X-Api-Key header of Authorization:
Bearer <key>.
Sommige endpoints zijn ook direct betaalbaar voor AI-agents via het x402-protocol
(https://www.x402.org) zonder account of API key: stuur een verzoek zonder key,
de server antwoordt met HTTP 402 en een PAYMENT-REQUIRED header (base64 JSON met
network, asset, amount, payTo). Teken daarna een EIP-3009 transferWithAuthorization
voor het gevraagde bedrag in USDC op Base en hertrail met een PAYMENT-SIGNATURE
header. De server verifieert, levert de data en settleert on-chain.
Tips voor agents:
- Lees eerst de PAYMENT-REQUIRED header van een 402-antwoord; die is leidend.
- Geef altijd de exact door de server gevraagde parameters mee.
- Een endpoint met een "x-payment-info" blok vereist betaling voor gebruik.'

description: 'Checks an IP address against 5 public DNSBL / RBL zones (Spamhaus, SpamCop,
SORBS, Barracuda, PSBL) by querying their DNS-based blacklists. This is a
lightweight, realtime check without any external API calls or rate limits.
Results are cached per IP for 1 hour.
Useful for inbound mail filtering, form submission blocking, and general
IP reputation checks. Combine with our email validation APIs for a full
anti-spam suite.'
