Human guide: work with your agent → Inspect one Polymarket action before starting provider-backed work. Your first result is a verified input and output contract.

​
Provider-specific requirements

Use Polymarket for read-only prediction-market data: what a market asks, what it is priced at, how that price moved, and how it resolved. There is no trading. Identifiers differ by tool, and all of them come from a market record:
  • id (numeric market id): polymarket_get_market.
  • clobTokenIds (one token per outcome, in the same order as outcomes): polymarket_get_price, polymarket_get_midpoint, polymarket_get_spread, polymarket_get_order_book, polymarket_get_price_history, polymarket_get_batch_price_history.
  • conditionId (0x hash): the market input of polymarket_list_trades, polymarket_get_holders, polymarket_get_open_interest.
  • event id: polymarket_get_live_volume.
  1. Find markets with polymarket_search (keyword) or polymarket_list_markets (filters). Search returns events with nested markets.
  2. A market record already carries current prices in outcomePrices, so pricing many markets needs no per-token call. Use polymarket_get_midpoint or polymarket_get_price for a fresh single quote, and polymarket_get_spread or polymarket_get_order_book to judge whether a thinly traded price is meaningful.
  3. For past prices, call polymarket_get_price_history with the outcome token as market. Use interval (1h, 6h, 1d, 1w, 1m, max) with a fidelity in minutes. An explicit startTs/endTs window longer than a few weeks is rejected as too long, so prefer interval: "max" with a coarse fidelity such as 1440 for long ranges. History remains available after a market resolves.
  4. For past results, call polymarket_list_markets with closed: true. A resolved market has umaResolutionStatus: "resolved" and outcomePrices of 1 for the winning outcome and 0 for the others.
Polymarket sends outcomes, outcomePrices, and clobTokenIds as JSON-encoded strings. Deepline results return them as arrays, index-aligned with each other. Prices are probabilities between 0 and 1, usually decimal strings. Timestamps in price history (t) are unix seconds. In polymarket_get_holders the top-level token of each group is masked as [REDACTED] by Deepline’s generic secret filter. Read the outcome token id from holders[].asset instead, and the outcome from holders[].outcomeIndex.

Find an applicable action

Confirm your effective workspace, then search the live catalog:
Search returns candidates. Check the returned provider and operation rather than selecting a similar title automatically.

​
Inspect the selected contract

Replace <returned-tool-id> with the identifier returned by discovery:
These commands do not execute the selected provider action. Read its required inputs, supported access mode, pricing unit, outputs, and limits. A connection does not establish that every action supports BYOK. Follow the provider-specific requirements above and the live action contract.

​
Prepare one reviewed input

Use one authorized record that matches the inspected schema. Preserve its source identity and define the result you will accept. Open the action reference for its payload and response shape. Provider-backed execution can incur usage or external effects. For reusable logic, follow Write Plays. For direct-call recovery, use Tool execution recovery.
Continue only when the workspace, provider, required fields, acceptance rule, and applicable price are understood. Keep unavailable access separate from no-result evidence.
