Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00140 | $0.04955 |
| Opus 5.5 | $0.00056 | $0.01982 |
| Sonnet 5.5 | $0.00028 | $0.00991 |
| Haiku 4.5 | $0.00014 | $0.00496 |
Grade A, and why
quantdata-max-pain 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 1mo 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.

The opening of the file, as written. The whole thing — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quant Data — Max Pain & Gamma Exposure
Options positioning for US-listed stocks and ETFs: max pain per expiration, the open-interest call and put walls, put/call ratio, and estimated dealer gamma exposure (GEX) with the zero gamma (flip) level.
There are three ways in. Check whether the environment variable QUANTDATA_API_KEY is set:
- Key present — use the JSON endpoints on
api.quantdata.uk. A free email key gives all four endpoints 10 shared successful calls per UTC day; a paid key removes that evaluation limit. The options routes cover any US-listed stock or ETF with a liquid options chain — not just the tickers that have free pages — and return machine-readable figures instead of rendered HTML. - No key, ticker not on the free pages — one anonymous first-look JSON response may succeed per source per UTC day. It is complete. For further calls, ask which email should receive a free key and use the request flow below.
- No key, ticker is on the free pages — read the public page instead and save the anonymous first look. It is the same number computed by the same code, and it costs nothing.
Never send an X-API-Key header to quantdata.uk. The static site does not read it, and
putting a key in a request to the wrong host is how keys leak into logs.
Without a key — the free pages
https://quantdata.uk/max-pain/{ticker} max pain, OI walls, put/call ratio, per expiration
https://quantdata.uk/gex/{ticker} net GEX, zero gamma (flip) level, gamma walls
GEX lives on its own page, not on the max-pain page — fetch both if the user wants both views. The ticker goes in lowercase in the path. An uppercase path 301-redirects to the lowercase one, so it works either way, but link and cite the lowercase form.
Coverage — always check, never assume
https://quantdata.uk/max-pain and https://quantdata.uk/gex are the authoritative lists. This document deliberately does not name the covered tickers, because a hardcoded list here goes stale silently the moment coverage changes — which has already happened once.
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.

quantdata-max-pain is a skill published in the GitHub repository celineycn/quantdata-plugin (1 stars, last pushed 2mo ago), licensed MIT. It adds 140 tokens to every session and 4,955 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
