Token cost

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

index-now scanned grade A with 0 findings 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 11d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

index-now

Instantly submit URLs for indexing across search engines using IndexNow protocol and Google Indexing API.

Capabilities

  • Submit URLs to IndexNow — Instantly notify Bing, Yandex, Naver, Seznam about new or updated pages
  • Submit to Google Indexing API — Request fast crawling from Google (requires service account)
  • Submit entire sitemaps — Parse sitemap XML and submit all URLs at once
  • Generate API keys — Create IndexNow API keys and verification files
  • Check indexing status — See when Google last received indexing notifications

IndexNow Setup

IndexNow requires two things:

  1. An API key (any UUID string)
  2. A verification file at your domain root (https://yourdomain.com/{key}.txt)

Generate a key:

# Generate a UUID
uuidgen
# Example: a1b2c3d4-e5f6-7890-abcd-ef1234567890

# Create verification file
echo "a1b2c3d4-e5f6-7890-abcd-ef1234567890" > public/a1b2c3d4-e5f6-7890-abcd-ef1234567890.txt

How to Submit URLs

IndexNow (Bing, Yandex, Naver, Seznam)

When asked to submit URLs for indexing:

  1. User needs an IndexNow API key (help them generate one if they don't have one)
  2. Submit to all engines simultaneously using the IndexNow API
  3. Report results per engine

Google Indexing API

Requires a Google Cloud service account with Indexing API enabled:

  1. Create a service account in Google Cloud Console
  2. Enable the Indexing API
  3. Add the service account email as an owner in Google Search Console
  4. Generate an access token

Supported Engines

Engine Protocol Daily Limit
Bing IndexNow Unlimited
Yandex IndexNow Unlimited

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
