Get the reviewed, versioned OilPriceAPI product contract for product scope, evaluation offer, pricing URL, freshness policy, catalog and entitlement wording, authentication, canonical first request, keyless demo, and data-rights boundaries. Use this instead of model memory or package prose for questions about OilPriceAPI itself. No API key or paid-data entitlement is required.

Get the latest available, source-timestamped value for an energy commodity. Use when the user asks about a single commodity's latest price. Accepts natural language ('brent oil', 'diesel') or API codes ('WTI_USD'). Returns price, currency, available change fields, and timestamp. For multiple commodities at once, use opa_market_overview. For price trends, use opa_get_history.

Get current prices for all tracked energy commodities in one call. Use when the user wants a broad market snapshot or asks about overall energy prices. Returns prices grouped by category (oil, gas, coal, refined products, metals, forex) with 24h changes. Supports filtering by category. For a single commodity, use opa_get_price instead.

Compare current prices between 2-5 commodities side by side. Use when the user asks to compare commodities (e.g., 'Brent vs WTI', 'US gas vs EU gas'). Returns each commodity's price with 24h changes, plus the spread if comparing two same-currency commodities. Accepts natural language or codes.

List all available commodities that can be queried for prices. Use when the user asks what commodities are available, what codes to use, or when another tool returns a 'commodity not recognized' error. Returns the full catalog fetched live from the API, grouped by category. No parameters needed.

Get historical price data for a commodity over a time period. Use when the user asks about price trends, historical prices, or how a commodity has performed over time. Returns high, low, average, change, and data point count. Periods: day (24h), week (7d), month (30d), year (365d).

Get the latest front-month futures contract price for energy commodities. Use when the user asks about futures, forward prices, or contract prices.

Get latest marine fuel (bunker) prices across major shipping ports. Use when the user asks about bunker fuel, marine fuel, VLSFO, MGO, IFO380, or shipping fuel costs. Can filter by port (e.g., SINGAPORE, ROTTERDAM, HOUSTON) and/or fuel type (VLSFO, MGO, IFO380). Returns a table of port prices.

Get the latest US oil and gas rig count data (Baker Hughes). Use when the user asks about drilling activity, rig counts, or oil field operations. Returns oil rigs, gas rigs, total count, and week-over-week change. No parameters needed.

Get a drilling activity snapshot: US, Canada, and international rig counts, frac spread count, well permits issued in the last 30 days (with a by-state breakdown), and DUC (drilled-uncompleted) well totals. Use when the user asks about drilling activity, rigs vs frac spreads, or upstream operations. Requires a paid plan with energy intelligence access.

Get the current average retail diesel price for a US state. Use when the user asks about diesel prices in a specific state, diesel fuel costs by state, or state-level fuel prices. Accepts state names ('California') or 2-letter codes ('CA'). Returns the AAA-sourced state average diesel price. Covers all 50 states plus DC.

Get carrier-published fuel surcharge percentages for LTL freight and parcel carriers. Use when the user asks about current or historical fuel surcharge rates for carriers like ODFL, Saia, Estes, XPO, ABF, TForce, Averitt, Southeastern Freight, UPS, FedEx, or DHL. Auto mode treats UPS/FedEx/DHL as parcel carriers and other carrier slugs as LTL. Parcel history requires a service_level such as ground, air, or international_air_export.

Get oil storage and inventory levels for Cushing, Oklahoma (WTI delivery hub) and/or the US Strategic Petroleum Reserve (SPR). Use when the user asks about oil inventories, storage levels, Cushing stocks, or the SPR. Returns current inventory levels with changes.

Get the latest OPEC oil production data. Use when the user asks about OPEC output, production quotas, supply cuts, or OPEC+ compliance. Returns country-level production figures. Requires a paid plan with energy intelligence access.

Get energy price forecasts from EIA Short-Term Energy Outlook (STEO) and other sources. Use when the user asks about price predictions, outlooks, or where oil/gas prices are heading. Returns forecast data for key commodities. Requires a paid plan with energy intelligence access.

Get the latest EIA weekly petroleum inventory (stocks) data. Use when the user asks about oil inventories, crude stocks, weekly EIA stocks, inventory builds/draws, or product-level inventory levels. Returns the latest weekly figures; optionally a summary view or a breakdown by petroleum product. Requires a paid plan with energy intelligence access.

Get the latest US oil & gas well drilling permit data. Use when the user asks about well permits, new drilling permits, permitting activity, or upstream permit trends. Returns the latest permits; optionally filtered/aggregated by state or by operator. Requires a paid plan with energy intelligence access.

Get US oil & gas well production data (BETA coverage: monthly state-level production from EIA + selected state regulators, and well-level histories for selected states only — NOT complete US well-level production). Views: summary (national + top states), states (all reporting states, latest month), state (monthly history for one state), well (monthly history for one well by 14-digit API number), top_producers (highest-output wells, optionally by state), cycle_time (permit-to-production cycle time stats, optionally by state), cohorts (cycle times by spud quarter). Use when the user asks about oil/gas production volumes by state or well, top producing wells, or drill-to-production cycle times. Requires a paid plan with energy intelligence access.

Get refining and trading spreads: crack spreads (refining margin proxy), basis spreads (regional price differentials), and blending/transport margins. Use when the user asks about crack spreads, 3-2-1 crack, refining margins, basis differentials, or blend/transport margins. Requires a paid plan with energy intelligence access.

List all PERSISTENT price alerts on the user's OilPriceAPI account. Use when the user asks what alerts they have set up, or to find an alert's id before deleting it. REQUIRES an API key (OILPRICEAPI_KEY) — alerts are account-scoped. No parameters needed.

Get recent trigger activity for the user's price alerts — which alerts have fired, how many times, and when they last triggered. Use when the user asks whether any alerts have gone off or about recent alert activity. REQUIRES an API key (OILPRICEAPI_KEY). Note: the API tracks trigger history as per-alert counters (trigger_count / last_triggered_at) rather than a separate event feed, so this returns alerts that have triggered.

Get a multi-commodity market brief: latest spot prices, 24h changes, 1-month forecasts (for Brent/WTI/Natural Gas), and notable spreads — for several commodities in ONE call. Use when the user wants a market snapshot, morning brief, or an at-a-glance read across multiple commodities. Set narrative: true to also get a plain-English summary plus market context (active supply disruptions, key economic indicators). Accepts natural language ('brent', 'us gas') or API codes. REQUIRES an API key (OILPRICEAPI_KEY); counts as 1 request. Per-tier code limits apply (free: 3 codes). For a single price use opa_get_price; for ongoing recurring monitoring use opa_create_price_subscription.

List all PERSISTENT price subscriptions ('watches') on the user's OilPriceAPI account. Use when the user asks what they're monitoring, or to find a watch's id before deleting it. Each watch is a recurring, account-tied snapshot job. REQUIRES an API key (OILPRICEAPI_KEY). No parameters needed.

Poll for new subscription events — the recurring snapshots recorded by the user's watches. Use this to catch up on what changed since the last poll: pass the since cursor (the seq number) returned by the previous call to get only newer events. Events are POLLED, not pushed — there is no always-on connection, so call this periodically to stay current. Each event carries a price snapshot plus per-code deltas vs the prior snapshot. The returned cursor is what you pass as since next time. REQUIRES an API key (OILPRICEAPI_KEY). This poll does NOT count against the monthly request quota.
