What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

zapmail-domain-setup-public scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

**CRITICAL: Comma encoding bug.** When building the URL in Python, default `urllib.parse.urlencode()` encodes commas as `%2C`, which breaks the batch request. Fix:

Cold Email Domain Setup: Dynadot + Zapmail (Public Edition)

Complete workflow to generate short domain names, purchase them on Dynadot, and set them up on Zapmail with inboxes ready for cold email sending.


First-Time Setup (Onboarding)

Before running anything, you need two API keys stored as environment variables.

1. Get Your Dynadot API Key

  1. Log into dynadot.com
  2. Go to Tools > API in the left sidebar
  3. Enable API access and copy your API key
  4. Whitelist your IP address (required by Dynadot)

2. Get Your Zapmail API Key

  1. Log into zapmail.ai
  2. Go to Settings > API
  3. Copy your API key

3. Store Your Keys

Add these to a .env file in your project root (or export them in your shell):

# .env — NEVER commit this file
DYNADOT_API_KEY=your_dynadot_key_here
ZAPMAIL_API_KEY=your_zapmail_key_here

Load them in your script:

import os
from dotenv import load_dotenv
load_dotenv()

DYNADOT_API_KEY = os.environ["DYNADOT_API_KEY"]
ZAPMAIL_API_KEY = os.environ["ZAPMAIL_API_KEY"]

4. Verify Access

Test both APIs before doing anything:

Dynadot — check wallet balance:

GET https://api.dynadot.com/api3.json?key=<YOUR_KEY>&command=account_info

Response includes AccountBalance (e.g., "$106.20").

Zapmail — list domains:

GET https://api.zapmail.ai/api/v2/domains/assignable?limit=10&page=1
Header: x-auth-zapmail: <YOUR_KEY>

If both return 200, you're ready.


Full Workflow Overview

Step 1: Generate domain name candidates         ~instant
Step 2: Check availability on Dynadot            ~1 min per 500 domains
Step 3: Purchase available domains               ~1 min per 100 domains
   | (domains now registered on Dynadot)
Step 4: Switch nameservers to Zapmail            ~1 min per 500 domains
   | WAIT 15-20 minutes for DNS propagation
Step 5: Connect domains on Zapmail               ~2 min per 500 domains
   | WAIT 10-30 minutes for domains to become assignable
Step 6: Create inboxes on Zapmail                ~3 min per 500 domains
   | WAIT 4-6 HOURS for inbox provisioning
Step 7: Export to your email sending platform    ~instant
