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 | $0.00224 | $0.02017 |
| Opus 5 | $0.00112 | $0.01009 |
| Sonnet 5 | $0.00045 | $0.00403 |
| Haiku 4.5 | $0.00022 | $0.00202 |
Grade A, and why
roic-api-v3 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 2d 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.

Send exactly one credential. Sending both is a 401.

Identifiers (the most common source of 400s)
identifier accepts only shapes that resolve to exactly one listing:
| Shape | Example | Notes |
|---|---|---|
| Qualified symbol | NASDAQ:AAPL |
exchange and symbol, colon separated |
| Public ID | tkr_cO46h8pgSu9Qqy, cmp_… |
returned in every id field |
| FIGI | BBG000B9XRY4 |
A bare AAPL, a CIK, a CUSIP, or an ISIN maps to several listings, so v3
rejects them with 400 invalid_parameter. Resolve them once through
/tickers/search?search_by=isin&query=US0378331005, cache the qualified
symbol, and reuse it. Forex uses its own shape: FX:EURUSD, or bare
EURUSD / EUR/USD / EUR-USD / EUR_USD.
Response shape
Lists return { "data": [...], "next_page_url": null, "previous_page_url": null }.
Single-resource routes return the object itself with no envelope. Two
price lists hoist the shared context to the top level: /stock-prices/{identifier}
adds symbol and currency, /forex-prices/{identifier} adds symbol.
Errors are Stripe-shaped and always carry a request_id:
{"error":{"type":"payment_required_error","code":"historical_data_restricted",
"message":"…","param":"date","request_id":"…"}}
Paginate by following next_page_url verbatim. The page value is an opaque
encrypted token bound to the exact filters and limit of the first call, and
it expires after 1 hour. Never construct, mutate, or persist it long-term.

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

roic-api-v3 is a skill published in the GitHub repository roicai/agents-plugin (2 stars, last pushed 26d ago), licensed MIT. It adds 224 tokens to every session and 2,017 once invoked, about $0.0011 per session on Opus 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.
