Pack catalog

Every first-party pack, generated from the pack index that packages/packs builds. Each one uses a credential you bring or a keyless public API; none uses a key B3OS pays for. Call an action as <pack>/<action>@<version> with POST /v1/actions/call, or let an agent find it with actions_search. GET /v1/actions/packs lists the packs your node serves.

A pack version is served once it is published to the registry and signed with the B3OS release key, which a person holds outside every automated system; nodes check each version's content hash and signature before they load it (signing). Connections are vault connections you create for the pack and key shown.

Read and write Google Sheets with your own Google OAuth token: spreadsheet metadata and tabs, values of one or several ranges, appending rows, updating and clearing ranges, and creating spreadsheets. Uses the Sheets API v4. Needs the spreadsheets scope (or spreadsheets.readonly for the read actions) from your own OAuth client.

Connection key	Type	What to store
google	oauth2	An OAuth access token for your Google account from your own Google Cloud OAuth client, with the scopes listed here.

get-event	read	polymarket__get-event	One Polymarket event by slug with every market in it: for a single question that is one market, for brackets or candidates one market per outcome.

Returns event summaries with their market count; call get-event with a slug for the markets and prices. At most 10 per page, because one busy event can carry hundreds of markets.
get-price	read	polymarket__get-price	Live price of one outcome token from the CLOB order book: best bid, best ask, midpoint, spread and last trade price, each 0 to 1. Null bid or ask means that side of the book is empty. Get token ids from a market's token_ids.

get-redeemable-positions	read	polymarket__get-redeemable-positions	Positions of a wallet in resolved markets that can be redeemed for USDC, according to the Data API's redeemable flag. Unlike the original action, there is no on-chain balance check, so a position redeemed moments ago can still appear.
