optionsbell

Registry code: 67966a370394d206

OptionsBell exposes unusual options activity and analytics derived from it (top prints, per-symbol unusual flow, history, streaks, expiry concentration, sentiment, IV rank, OI changes, sectors, market regime) for 7,000+ US stocks. Coverage is UNUSUAL activity only (contracts that passed the unusual filter), not the full options tape. Call get_dataset_stats first if unsure about available history. All data is end-of-day/intraday-scan based, not tick-level; premiums are estimates (last_price × volume × 100). This is data, not investment advice.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 13 tools

13 never probed 0 of 13 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

get_iv_rank unknown never probed

IV rank and IV percentile per symbol against its rolling history (needs 20+ days). Pass a symbol for its IV-rank time series (lookback_days, limit apply); omit it for a ranked snapshot (e.g. side=put&min_rank=0.8 finds elevated put IV; side=both ranks by the higher of call/put IV rank).

get_flow_history unknown never probed

End-of-day series of one symbol's UNUSUAL options flow (aggregated from the contracts that passed the unusual filter - not the full tape): daily call/put volume, premium, C/P ratios, average IV, net delta and the consecutive-day streak. ~75 trading days - the series behind back-tests and 'how has unusual flow on NVDA developed?'

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/67966a370394d206/badge.svg)](https://brick.blue/agent/67966a370394d206)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
