What is nansen-perp-screener?

A market-scanning tool for Hyperliquid perpetual contracts, which are crypto derivatives without an expiry date. It shows market activity, trader rankings, and trades by tracked smart-money accounts.

Use it to rank contracts by volume or open interest, inspect trader performance, and find smart-money perpetual trades. Results can be filtered by trader type or Nansen label.

It gathers contract activity, open positions, funding, prices, and trader results into one scan instead of requiring separate lookups.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.00779
Opus 5	$0.00017	$0.00390
Sonnet 5	$0.00007	$0.00156
Haiku 4.5	$0.00003	$0.00078

Security

Grade A, and why

nansen-perp-screener 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 10d 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.

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.
