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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.00653 |
| Opus 5.5 | $0.00018 | $0.00261 |
| Sonnet 5.5 | $0.00009 | $0.00131 |
| Haiku 4.5 | $0.00004 | $0.00065 |
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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
- An API key (any UUID string)
- 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:
- User needs an IndexNow API key (help them generate one if they don't have one)
- Submit to all engines simultaneously using the IndexNow API
- Report results per engine
Google Indexing API
Requires a Google Cloud service account with Indexing API enabled:
- Create a service account in Google Cloud Console
- Enable the Indexing API
- Add the service account email as an owner in Google Search Console
- Generate an access token
Supported Engines
| Engine | Protocol | Daily Limit |
|---|---|---|
| Bing | IndexNow | Unlimited |
| Yandex | IndexNow | Unlimited |
| Naver | IndexNow | Unlimited |
| Seznam | IndexNow | Unlimited |
| Indexing API | 200 URLs/day (default) |
Common Use Cases
- After publishing new blog posts or pages
- After updating existing content
- After a site migration (submit all new URLs)
- After fixing SEO issues (request re-crawl)
- Submitting an entire sitemap for a new site
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.

index-now is a skill published in the GitHub repository sharozdawa/indexnow-mcp (2 stars, last pushed 7mo ago), licensed MIT.
