MISO PRA Capacity-Market Results (internal) API v1

Generated from core.contract.describe_power_capacity_market_miso_v1() and checked fixture-backed examples. Do not hand-edit the example JSON files.

Capability

• Capability: power.capacity_market_miso
• Primitive: query_power_capacity_market_miso_v1
• Status: available
• Current source: energy.miso.pra
• Source publisher: Midcontinent Independent System Operator, Inc.
• Snapshot behavior: as_of = latest resolves to an exact snapshot date in every response.

What It Can Answer

• MISO PRA seasonal zonal ACP and verbatim ERZ values, including published ERZ ranges.
• Seasonal subregional and annual zonal CONE exactly where the posting states them.
• IMM conduct thresholds and raw PDF page-row evidence for every returned value.

Represented Facts

• MISO Planning Resource Auction results as published in the annual PRA results posting: seasonal zonal Auction Clearing Prices in USD per MW-day of Seasonal Accredited Capacity for Zones 1-10, External Resource Zone clearing quoted verbatim where the document states a range, seasonal subregional and annual zonal Cost of New Entry values, and the Independent Market Monitor conduct thresholds the posting publishes beside them. CONE is recorded as the document's stated administrative parameter — the price-cap analog — on the basis its stating document uses, never interpreted, annualized, or converted by this block. A corrections posting is a distinct document identity: its atoms cite the corrections file, and earlier postings are never silently replaced.

Data Point Contract

• Data point: power.capacity_market_miso
• Product spec: blocks/power_capacity_market_miso/card.md
• Grain: auction_planning_year_season_zone_or_parameter
• Source basis: energy.miso.pra
• Represented fact: MISO Planning Resource Auction results as published in the annual PRA results posting: seasonal zonal Auction Clearing Prices in USD per MW-day of Seasonal Accredited Capacity for Zones 1-10, External Resource Zone clearing quoted verbatim where the document states a range, seasonal subregional and annual zonal Cost of New Entry values, and the Independent Market Monitor conduct thresholds the posting publishes beside them.

Does not answer:

• energy-market LMPs, day-ahead or real-time prices, or plant revenue
• PRMR, LCR, CIL/CEL, cleared-MW, or offer-curve quantities (published in the posting but out of v1 scope)
• pre-2024 planning years (the postings' historical comparison tables are out of v1 scope)
• a demand-curve position, scarcity interpretation, or effective capacity price
• ZRC-to-UCAP conversions, resource-specific accreditation, or FRAP volumes

Local MCP Setup

Some MCP clients launch servers from the user's home directory or ignore a configured cwd. Use uv run --directory so the server always starts from the repository project.

{
  "command": "uv",
  "args": [
    "run",
    "--directory",
    "/absolute/path/to/OSINT",
    "python",
    "-m",
    "core.mcp_server"
  ]
}

Leave EXASCALE_PARQUET_BASE / EXASCALE_RAW_BASE unset: the one server hosts every data point's tools, and with no override it resolves each block's promoted snapshots and raw archive from the repository layout. Setting either env var points ALL tools at one directory — a per-block path breaks every other block's tools. They exist only for single-source sandboxes and tests.

Request Schema

Filters:

• as_of
• auction_label
• planning_year
• season
• zone
• scope
• atom_type

Group by:

• auction_label
• planning_year
• season
• zone
• scope
• atom_type

Date range parameters:

Controls:

• include_records
• include_evidence
• limit
• order_by
• top_n
• order
• rollup_other

Ranking (how order_by / top_n / order join — order_by ranks groups by a metric, never a group_by dimension; top_n needs both a group_by and an order_by):

{
  "no_ranking": "Omit order_by and top_n to return all groups in group-key order.",
  "order": {
    "default": "desc",
    "valid_values": [
      "desc",
      "asc"
    ]
  },
  "order_by": {
    "accepts": "one of output.metrics",
    "note": "Ranks the groups by a metric (a measure). Not a group_by dimension \u2014 rows already come back grouped by each group_by field.",
    "requires": [
      "group_by"
    ],
    "valid_values": [
      "avg_acp_usd_mw_day",
      "min_acp_usd_mw_day",
      "max_acp_usd_mw_day",
      "cone_usd_mw_day",
      "imm_conduct_threshold_usd_mw_day",
      "source_record_count"
    ]
  },
  "top_n": {
    "note": "Keeps the top N groups by order_by; the rest fold into one (other) remainder (additive metrics sum into it, non-additive ones are nulled) so the result still reconciles to summary.totals.",
    "requires": [
      "group_by",
      "order_by"
    ],
    "type": "positive integer"
  }
}

Output Schema

Aggregate metrics:

• avg_acp_usd_mw_day
• min_acp_usd_mw_day
• max_acp_usd_mw_day
• cone_usd_mw_day
• imm_conduct_threshold_usd_mw_day
• source_record_count

Metric groups:

{
  "price": [
    "avg_acp_usd_mw_day",
    "min_acp_usd_mw_day",
    "max_acp_usd_mw_day",
    "cone_usd_mw_day",
    "imm_conduct_threshold_usd_mw_day"
  ],
  "records": [
    "source_record_count"
  ]
}

Response summary fields:

• group_count
• totals

Accepted fact policy:

• Query responses contain accepted, gate-passed facts only.
• Gate, monitor, and audit quality signals are internal controls, not agent-facing answer caveats.
• If a source snapshot is not fit to serve, the source must fail closed before it reaches this API.

Metric metadata:

Rollup rules:

• summary.totals.<metric> is the authoritative total for the full matched query.
• Grouped row metrics may be summed only when additive_across_groups is true.
• Do not sum grouped values for these non-additive metrics: avg_acp_usd_mw_day, min_acp_usd_mw_day, max_acp_usd_mw_day, cone_usd_mw_day, imm_conduct_threshold_usd_mw_day.

Detail record fields returned when include_records is true:

• source_id
• sheet_name
• iso
• auction_label
• planning_year
• season
• zone
• scope
• atom_type
• acp_usd_mw_day
• acp_erz_verbatim
• cone_usd_mw_day
• imm_conduct_threshold_usd_mw_day
• report_period
• source_record_key
• source_row_number
• as_of
• raw_file_sha256
• citation

Row-level citation fields:

• source_id
• source_url
• source_file
• sheet
• source_row
• raw_file_sha256
• as_of

Aggregate citation fields:

• source_id
• publisher
• source_url
• source_file
• raw_file_sha256

Agent Workflow

1. Call list_capabilities_v1 and select power.capacity_market_miso.
2. Call describe_power_capacity_market_miso_v1 to inspect valid filters, groupings, metrics, and citation fields.
3. Call query_power_capacity_market_miso_v1 with bounded JSON params.
4. If the answer needs proof, pass a returned row-level citation object to get_source_evidence_v1.
5. Answer with the resolved as_of and relevant citations. Present returned metrics as authoritative for their declared source, snapshot, grain, and aggregation.
