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 | $0.07478 | $0.07478 |
| Opus 5.5 | $0.02991 | $0.02991 |
| Sonnet 5.5 | $0.01496 | $0.01496 |
| Haiku 4.5 | $0.00748 | $0.00748 |
Grade A, and why
quantdata-plugin GEMINI.md 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 — 426 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quant Data
Measured market statistics for stocks, ETFs and futures, served over plain HTTP. This context file teaches you, the agent, how to fetch these numbers and — more importantly — how to report them honestly.
The honest summary: the measured edges are 52–56%, published together with their baselines, sample sizes and the places the methods fail. Every percentage in this file traces to a real measurement. None of it is a forecast, and none of it is investment advice.

Authentication and pricing
Read the key from the environment variable QUANTDATA_API_KEY. Never write a key into a
file, into generated code, into a commit, or into a message back to the user.
If the variable is unset, one complete anonymous first-look response may succeed per source per
UTC day. Its legacy-named free_tier object carries access_kind: "anonymous", the reset time,
and the next action.
For continued evaluation, ask the user which email address should receive a free key. Never invent an address. Then make this request:
curl -s -X POST https://api.quantdata.uk/v1/access/free-key \
-H 'Content-Type: application/json' \
-d '{"email":"[email protected]","marketing_opt_in":false,"source":"agent"}'
If Quant Data is connected over MCP, call quantdata_request_free_api_key instead. The raw
qd_ key is delivered only to that inbox and never returned in the REST or MCP result. No login,
password, card or GUI is required. The free key covers all four endpoints, sharing 10 successful
calls per UTC day.
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.
