For Agents

Install Jentic One Beta

Connect the Daymet Single Pixel Extraction Tool API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Daymet Single Pixel Extraction Tool API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Daymet Single Pixel Extraction Tool API.

Extract a daily climate time-series at a latitude/longitude through GET /api/data with a year range and variable list

Generate a quick visual preview of the requested variables via GET /preview

Send the extracted dataset to a saved-data endpoint with GET /send/saveData for downstream retrieval

View OpenAPI Document

Jentic publishes the only available OpenAPI specification for Daymet Single Pixel Extraction Tool API, keeping it validated and agent-ready. Daymet is a NASA-funded gridded climate dataset hosted by Oak Ridge National Laboratory's DAAC, providing daily weather variables across North America at one-kilometre resolution from 1980 to the near-present. The Single Pixel Extraction Tool exposes four endpoints to extract a time-series at a given latitude/longitude for variables such as minimum and maximum temperature, precipitation, vapor pressure, shortwave radiation, snow water equivalent, and day length. It is suitable for hydrology, agriculture, and climate-impact modelling that needs reproducible historical weather at point locations.

Use Cases

Patterns agents use Daymet Single Pixel Extraction Tool API for, with concrete tasks.

★ Reproducible Climate Inputs for Hydrology Models

Hydrologists running watershed models often need point-scale daily forcings. GET /api/data returns a CSV time-series for the requested variables at a coordinate, ensuring every model run uses the same Daymet grid version and avoiding ad hoc weather-station gap filling.

GET /api/data?lat=35.96&lon=-83.92&vars=tmin,tmax,prcp&year=1980-2024 and feed the CSV into the hydrology model's forcings module.

Crop Phenology and Agricultural Modelling

Agronomists modelling crop development can pull daily Tmin, Tmax, and day length from Daymet at a field-level coordinate. The four endpoints cover both data extraction and visual sanity checks, helping verify that a long time-series has no obvious anomalies before it feeds a growing-degree-day model.

GET /api/data with vars=tmin,tmax,dayl for a field coordinate, then GET /visualize to confirm continuity before feeding into the GDD calculator.

Climate Impact Risk Assessment

Insurers and ESG teams assessing climate risk at specific assets can use Daymet to build historical baselines for precipitation extremes and temperature anomalies. The free, citable dataset removes licensing friction for reports requiring auditable provenance.

GET /api/data?lat=&lon=&vars=prcp&year=1980-2024 for each asset coordinate and compute the 99th-percentile daily precipitation.

Agent-Driven Weather Lookups via Jentic

Research and analytics agents can pull historical Daymet weather for any North American coordinate through Jentic without configuring the ORNL endpoint manually. Jentic exposes the four operations by intent and handles parameter formatting.

Use Jentic to search 'extract historical weather for a coordinate', load the GET /api/data schema, and execute with the lat/lon and variable list.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Daymet's single-pixel API does not require credentials, but Jentic still routes the request through the platform for unified logging and rate management alongside credentialed APIs.

Intent-based discovery

Agents search by intent (e.g., 'extract historical weather for a coordinate') and Jentic returns the matching Daymet operation with its input schema and parameter formatting.

Time to first call

Direct Daymet integration: a few hours for parameter formatting and CSV parsing. Through Jentic: minutes — search, load, execute.

FAQs

Specific to using Daymet Single Pixel Extraction Tool API through Jentic.

Why is there no official OpenAPI spec for Daymet Single Pixel Extraction Tool API?

ORNL DAAC publishes Swagger documentation for Daymet but not a maintained, agent-ready OpenAPI document. Jentic generates and maintains this spec so that AI agents and developers can call Daymet Single Pixel Extraction Tool API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Daymet API use?

The single-pixel extraction endpoints are public and do not require authentication in this spec. Through Jentic the request is still routed via the platform so usage is logged consistently with other agent operations.

Can I extract daily precipitation for a coordinate with the Daymet API?

Yes. GET /api/data accepts lat, lon, and a vars list including prcp (precipitation) along with tmin, tmax, dayl, srad, swe, and vp, returning a daily CSV time-series.

What are the rate limits for the Daymet API?

ORNL DAAC does not declare numeric rate limits in the spec. Heavy users are encouraged to download bulk Daymet files instead — confirm acceptable single-pixel volumes with the DAAC if you plan to extract thousands of points per day.

How do I extract a Daymet time-series through Jentic?

Search Jentic for 'extract historical weather for a coordinate', load the GET /api/data schema, and execute with lat, lon, year range, and the comma-separated variable list.

Is the Daymet API free?

Yes. Daymet is funded by NASA and distributed without charge through ORNL DAAC for research and operational use. Citation of the dataset is requested for published work.
