Oo Clinicaltrials Gov

ClinicalTrials.gov

Operate ClinicalTrials.gov through your OOMOL-connected account. This skill calls the clinicaltrials_gov connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

ClinicalTrials.gov needs no account connection. Assume the oo CLI is installed and signed in. Do not run oo auth login proactively — just run the action. Fall back to First-time setup only when a command actually fails.

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

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

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

oo connector run "clinicaltrials_gov" --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_api_version — Get the current ClinicalTrials.gov API version and daily data refresh timestamp.
• get_field_value_statistics — Get value statistics for selected ClinicalTrials.gov leaf fields or field data types.
• get_list_field_size_statistics — Get observed list-size statistics for selected ClinicalTrials.gov array fields.
• get_registry_size_statistics — Get ClinicalTrials.gov registry counts and the distribution of study JSON record sizes.
• get_studies_by_nct_ids — Get multiple ClinicalTrials.gov studies by NCT identifier and report identifiers that were not found.
• get_study — Get one ClinicalTrials.gov study by NCT identifier.
• get_study_documents — List uploaded study protocols, statistical analysis plans, and informed consent forms with their official metadata.
• get_study_eligibility — Get patient-facing eligibility criteria, age and sex requirements, and study population details for one ClinicalTrials.gov study.
• get_study_locations — Get study sites, geographic coordinates, central contacts, local contacts, and study officials for one ClinicalTrials.gov study.
• get_study_metadata — Get the official ClinicalTrials.gov study data model and field definitions.
• get_study_results — Get posted participant flow, baseline characteristics, outcome measures, adverse events, and result notes for one ClinicalTrials.gov study.
• list_enums — List official ClinicalTrials.gov enumeration types, values, legacy values, and field usages.
• list_search_areas — List the official ClinicalTrials.gov search documents, areas, parameters, and indexed pieces.
• search_studies — Search ClinicalTrials.gov studies with official Essie queries, filters, field selection, sorting, and cursor pagination.

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change ClinicalTrials.gov 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):

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

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

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

  oo auth login
  

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