About

The Delphi Epidata API is an open access epidemiological query platform maintained by the Delphi Research Group at Carnegie Mellon University. Designed to support real-time outbreak tracking and forecasting, Epidata unifies multi-source disease surveillance signals including CDC FluView ILI indicators, COVIDcast symptomatic surveys, Google health search trends, wastewater viral monitoring, and clinical testing metrics into a single programmatic JSON API.

Through Fibric, an operator references standardized regional epidemiological time-series and geographic trend signals, proposing localized workforce contingency plans, shift balancing, and seasonal operational staffing adjustments across US metropolitan areas.

This is a reference listing. It documents what Fibric would read from Delphi Epidata API and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Standardized time-series endpoints querying multi-source epidemiological signals across US counties, MSAs, and states
  • COVIDcast symptom survey indicators measuring community self-reported illness frequencies and masking rates
  • CDC FluView and ILINet outpatient influenza-like illness percentages formatted across uniform geographic resolutions
  • Digital health indicators including search symptom volumes and doctor visit diagnostic ratios
  • Standard JSON responses containing smoothed signal estimates, standard errors, and sample sizes

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Aggregate multi-pathogen surveillance signals for facility planning

    Query combined FluView and wastewater metrics via Epidata, proposing pre-scheduled shift coverage and cross-training for distribution centers in rising transmission zones.

    With Shift Coverage, Open Shift Offer

  • Detect localized respiratory illness surges across metropolitan sites

    Monitor MSA-level outpatient illness trends, proposing updated environmental air ventilation setpoints and cleaning schedules for corporate offices located in affected clusters.

    With CO2 Ventilation, Cleaning Verification

Requirements

  • HTTP client capable of querying Delphi Epidata REST endpoints via GET or POST requests
  • Signal specification parameters defining source name, signal identifier, geographic type, and time window
  • Adherence to anonymous rate limit pacing or registration of a free Delphi API key
Authentication
None. The Delphi Epidata API allows anonymous queries subject to rate limits; users can obtain a free registered API key for higher call limits.

Limits

  • Certain legacy COVIDcast signals were retired or frozen following the conclusion of daily symptom surveys
  • Statistical estimates include revision histories as state health agencies issue delayed retrospective reports
  • Geographic coverage focuses on the United States with varying spatial resolution across specific signals

Questions and answers

What signals are available through the Delphi Epidata API?
Epidata aggregates COVIDcast indicators, CDC FluView, wastewater surveillance, digital search trends, and hospital admission data.
Is an API key required to query Epidata?
No. Anonymous querying is supported with rate limiting. A free registered API key is available for high-throughput automated applications.
What license governs Delphi Epidata data?
Delphi Epidata client libraries and aggregate data feeds are open source, licensed under the MIT License and Creative Commons terms.
