Massive (Polygon.io)

Massive (Polygon.io) (massive.com). Use this skill for ANY Massive (Polygon.io) request — searching and reading data. Whenever a task involves Massive (Polygon.io), use this skill instead of calling the API directly.

Operate Massive (Polygon.io) through your OOMOL-connected account. This skill calls the polygon_io connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

Assume the user has already installed the oo CLI, signed in, and connected Massive (Polygon.io). Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

bash

oo connector schema "polygon_io" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

bash

oo connector run "polygon_io" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

Available actions

• get_aggregate_bars — Get historical OHLC aggregate bars for a stock ticker over a custom range.
• get_market_status — Get the current Polygon.io market status for stocks, currencies, and indices.
• get_previous_day_bar — Get the previous trading day's OHLC aggregate bar for a stock ticker.
• get_ticker_details — Get comprehensive details for a single Polygon.io ticker.
• list_exchanges — List known exchanges available through Polygon.io.
• list_ticker_types — List ticker type codes supported by Polygon.io.
• list_tickers — List ticker symbols supported by Polygon.io with optional filters.

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change Massive (Polygon.io) state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

  bash

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  

  powershell

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  

• Not signed in / authentication error — sign in to your OOMOL account once:

  bash

  oo auth login
  

• scope_missing / credential_expired / app_not_ready / app_not_found — Massive (Polygon.io) is not connected, or the connection expired or lacks a scope. Connect once (auth type: API key) at:

  text

  https://console.oomol.com/app-connections?provider=polygon_io
  

• HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
