OpenMarket

Category: Market data · signals

OpenMarket serves crypto derivatives and prediction-market data. Thirdfy exposes it as two read-only providers. Agents call get_openmarket_* on the Thirdfy catalog. These actions never place orders.

Exchanges (19 markets): Binance (perps, coin-margined and spot), Bybit (perps and spot), OKX (swaps and spot), Deribit, BitMEX, Bitfinex (perps and spot), Gate (perps and spot), Hyperliquid (perps, HIP-3 and spot), Coinbase, Bitstamp and Upbit. Polymarket has its own reads.

Actions

Market data (openmarket):

Series reads take exchange, symbol (the venue's own symbol: BTC on HYPERLIQUID_FUTURES, BTCUSDT on BINANCE_FUTURES), interval (MINUTE to WEEK) and period in seconds. Values carry their unit. An unknown symbol returns empty arrays.

Indicators and chart levels (openmarket-metrics):

An indicator OpenMarket cannot compute returns ok: false with an error and a detail.reason that names an interval that fits. It never returns a guessed value.

Signal reads (openmarket, fixed shapes for strategies):

Every read costs 2.5 credits (read_offchain). Command shows the USD charge after the turn. See Credits and balance.

Reading a chart

Agents read charts as numbers. One pass for "how does SOL look on Hyperliquid, and where are the key levels":

1. get_openmarket_metrics_symbol_resolve { "query": "solana" }. On Hyperliquid perps the symbol is the coin ticker, SOL.
2. get_openmarket_candles { "exchange": "HYPERLIQUID_FUTURES", "symbol": "SOL", "interval": "HOUR", "period": 86400 }: close, change and range.
3. get_openmarket_metrics_indicators on FIFTEEN_MINUTES: RSI, MACD and signal, Bollinger Bands, ATR, EMA, funding.
4. get_openmarket_metrics_volume_profile { "rawSymbol": "SOL", "exchanges": ["HYPERLIQUID_FUTURES"], "interval": "DAY", "lookback": "3d" }: point of control, value area and thin zones.
5. get_openmarket_order_flow: are buyers or sellers aggressive?
6. get_openmarket_hl_funding and get_openmarket_hl_open_interest: positioning.

Chart images and a person's own open OpenMarket chart are not available to agents.

History and rate limits

OpenMarket plans set what Thirdfy can serve. Today:

• History is 167 hours (about 7 days). Series reads take a period of at most 601200 seconds.
• Indicators warm up on about 4 times their period. On 15-minute bars every common setting works. On hourly bars, short periods work (RSI 14) and long ones (EMA 50) do not. On 4-hour and daily bars, indicators return tier_forbidden with the interval that fits.
• Requests are rate limited. A read that hits the limit fails with PROVIDER_APP_UPSTREAM_RATE_LIMITED. Retry after a minute.
• Hyperliquid liquidations are sparse in this data. Use a CEX perp (Binance, Bybit) for liquidation flow.

Signals

The five signal reads above publish signals in the signal manifest (app openmarket, manifest version 1). Each signal comes from the read of the same name and costs 2.5 credits. Its time is when Thirdfy fetched it (freshness.fetchedAt).

Values may be shown to users with the line "Data: OpenMarket" (displayValues: true). The raw reply may not be shown (displayRaw: false).

Credential model

OpenMarket reads use the same Thirdfy session as other catalog actions. CLI and MCP do not take an OpenMarket key. Thirdfy holds the key and sends it only to OpenMarket's host. Thirdfy credits pay the catalog action.

Discovery

curl "https://api.thirdfy.com/api/v1/agent/actions/catalog"
thirdfy-agent actions --provider openmarket --json

Readiness checklist

• Agent authenticated for discovery and run (email OTP agent_wallet or agent API key per lane).
• The agent's allowed actions include the get_openmarket_* reads it needs.
• Strategy treats OpenMarket output as advisory evidence and checks parseIssues and ok before using a value.

No wallet, delegation or venue setup is needed. The reads are fanoutSafe.
