Building a reliable autonomous AI agent means acquiring the state of the physical and financial world from dependable, verified sources. The naive alternative is maintaining hundreds of bespoke scrapers, each vulnerable to upstream HTML shifts, unpredictable rate limits, schema breakages, and uncoordinated polling cadences.

pronto.stream operates an enterprise ingestion pipeline reconciling 99 verified public API endpoints and 96,455 RSS feeds across 249 countries into one unified stream on a single temporal clock.

The Timestamp Discipline: Observation Time vs Ingest Time

Every signal emitted by pronto.stream carries both an observed_at timestamp (when the physical seismograph shook, the weather station recorded the gust, or the SEC filing was clocked) and an ingested_at timestamp (when the signal entered the Pronto engine). This allows AI agents to reason about real-world publication latency and guarantees reproducible historical backtesting.

Core Ingestion Pillars

Seismic & Physical Hazards

USGS earthquakes, BMKG Indonesia, EMSC Europe, JMA Japan, GDACS, and NASA EONET. Five seismic agencies locate events independently, feeding our multi-agency consensus model.

Climate & Meteorology

Open-Meteo (forecasts, air quality, solar radiation, and marine wave heights), MET Norway, NOAA National Weather Service alerts, and Dutch Luchtmeetnet air monitoring.

Global News Wire

96,455 verified RSS feeds across 249 countries, plus GDELT, Hacker News, Wikimedia trending, and Spaceflight News. Syndicated text remains copyright its original publisher.

Logistics & Trade

Open-Meteo marine sea state, observed METAR/TAF aviation weather across global hub airports (feeding our aviation network stress model), and port authority logistics bulletins.

Energy & Grid Carbon

UK National Grid ESO carbon intensity, Energinet (Denmark), and Grünstromindex (Germany) providing real-time grid generation mix and emissions factors.

Financial, Filings & Macro

SEC EDGAR Form 4 insider filings, US Treasury yield curves, US Bureau of Labor Statistics, World Bank WDI, European Central Bank (ECB) and Bank of Canada reference rates.

How a Source Becomes a Verified Row

Raw payloads from upstream APIs undergo immediate multi-stage transformation within the Go ingestion pipeline:

  1. Deduplication: Cryptographic hashing of primary identifiers prevents duplicate alerts across polling cycles.
  2. Schema Normalization: Heterogeneous JSON, XML, and GeoJSON structures are mapped into the protobuf-defined signal.v1 schema.
  3. Spatio-Temporal Gazetteering: Global coordinates are resolved against GeoNames municipal centroids to populate canonical place IDs and country codes.
  4. Confidence Scoring: Each signal is assigned a confidence metric based on source completeness, transport latency, and multi-sensor corroboration.

Direct MCP & REST Ingestion Access

Autonomous agents query live and scoped feeds via the Model Context Protocol tools get_latest_signals, scope_signals, and list_data_sources. Each connector's licensing terms, fetch cadence, and endpoint provenance can be audited in real time.
