Install Jentic One Beta

Connect the Transportation Laws and Incentives to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Transportation Laws and Incentives, 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fnrel.gov%2Fnrel" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fnrel.gov%2Fnrel" | 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

Use Cases

Patterns agents use Transportation Laws and Incentives API for, with concrete tasks.

★ Fleet Electrification Eligibility Research

Fleet operators evaluating EV transitions use this API to identify federal and state incentives applicable to their jurisdictions and vehicle classes. Querying /v1.{output_format} with a state filter returns the active law set, and /v1/{id}.{output_format} fetches the full text of any incentive cited in a procurement memo. This avoids manually scraping afdc.energy.gov.

Call GET /v1.json?state=CA and filter results to EV charging infrastructure incentives for a 2026 fleet plan

Alt-Fuel Compliance Tracking

Automakers and energy consultants track the changing landscape of state alt-fuel laws to advise clients on compliance and rebates. The /v1/category-list.{output_format} endpoint returns the canonical taxonomy AFDC uses, and incentive records are versioned so apps can flag new or amended laws. Combining categories with state filters supports periodic compliance dashboards.

Call GET /v1/category-list.json then GET /v1.json?category=tax_incentives&state=NY for a New York compliance brief

AI Agent Incentive Lookup via Jentic

Energy-policy AI agents use Jentic to discover this API and answer user questions like "what EV rebates apply to a Texas resident in 2026". The agent calls /v1.json with the state filter, parses the relevant incentive records, and returns a summary with citations to the underlying AFDC law IDs.

Use Jentic to search 'state EV rebate by jurisdiction', load /v1.{output_format}, and execute with state=TX

Key Endpoints

4 endpoints — the nrel transportation laws and incentives api queries a curated database of us federal and state laws and incentives covering alternative fuels, vehicles, air quality, and fuel efficiency.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the Transportation Laws and Incentives API by hand means obtaining an api.data.gov key, appending it to every request to developer.nrel.gov, and handling the output-format suffix and filter parameters yourself. Through Jentic you install once, import the Transportation Laws and Incentives API from the API Directory, store the API key once, and your agent calls it.

Permission scoping

This API puts the law or incentive id in the URL path (/v1/{id}.{output_format}), so a rule can pin your agent to one record. Every operation here is a read-only lookup, so you choose whether the agent lists laws, reads categories, or fetches a single record.

Credential isolation

Your api.data.gov key for NREL is stored once, encrypted, by your own Jentic One instance and injected as the api_key query parameter at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'look up a state EV rebate' or 'list alt-fuel incentive categories', and Jentic returns the matching operation with its filter schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Transportation Laws and Incentives API through Jentic.

What authentication does the Transportation Laws and Incentives API use?

It uses an api.data.gov API key passed as the api_key query parameter, the same key infrastructure used across NREL and other federal APIs. Through Jentic, the key is held encrypted in the vault and injected at execution time so it never appears in agent prompts.

Can I filter laws by state with the Transportation Laws and Incentives API?

Yes. GET /v1.{output_format} accepts a state query parameter that returns laws and incentives applicable to that jurisdiction, including federal entries that apply nationally.

What are the rate limits for the Transportation Laws and Incentives API?

The default api.data.gov tier allows 1,000 requests per hour per API key. NREL does not impose tighter limits on this dataset, but their developer portal at developer.nrel.gov publishes any deviations.

How do I retrieve a specific incentive record through Jentic?

Search Jentic for 'NREL incentive lookup by id', load the GET /v1/{id}.{output_format} schema, and execute with the record id and desired output format. The flow is pip install jentic, then await client.search, load, and execute.

Is the Transportation Laws and Incentives API free?

Yes. It is free under the api.data.gov terms; you only need to register for a key and respect the per-hour request limit.

Can I limit what my agent is allowed to do with the Transportation Laws and Incentives API?

Yes. Because you run Jentic One yourself, your own rules decide which of the four read-only operations your agent may call, so you can allow it to search laws with GET /v1.{output_format}, list categories with GET /v1/category-list.{output_format}, read contacts with GET /v1/pocs.{output_format}, or fetch a single record with GET /v1/{id}.{output_format} while blocking the rest. Since the record id sits in the URL path of /v1/{id}.{output_format}, a rule can even pin your agent to one specific incentive record. Every endpoint is a lookup that only reads data, so no rule you set can let the agent write to or change the AFDC dataset.

For Agents

Query US federal and state laws and incentives for alternative fuels, EVs, and air quality through 4 endpoints. Free with an api.data.gov key.

Use for: Find all EV charging incentives in California, Get the federal tax credit details for hydrogen fuel cell vehicles, List incentive categories tracked by the AFDC, Retrieve incentive record 1234 in JSON

Not supported: Does not handle EV charging station locations, fuel pricing, or grant applications - use for federal and state alt-fuel law and incentive records only.

The NREL Transportation Laws and Incentives API queries a curated database of US federal and state laws and incentives covering alternative fuels, vehicles, air quality, and fuel efficiency. It powers the Federal and State Laws and Incentives section of the Alternative Fuels Data Center at afdc.energy.gov. Four endpoints return list views, a category list, the contacts (points of contact) table, and a single-record lookup, with results available in multiple output formats via the {output_format} path parameter.
