Install Jentic One Beta

Connect the Country to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Country, 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%2Fcountry.is%2Fcountry-is" | 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%2Fcountry.is%2Fcountry-is" | 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 Country API.

Look up the calling client's country by IP with a single GET request

Resolve a specific IPv4 or IPv6 address to its ISO country code

Batch-resolve up to a list of IP addresses in one POST

Retrieve service info such as version and dataset metadata

Embed lightweight country detection in edge or serverless workloads

Use Cases

Patterns agents use Country API for, with concrete tasks.

★ Visitor Country Detection

Resolve a visitor's country from their IP address to localise content, currency, or feature flags. country.is needs no API key and returns just an ISO alpha-2 code, which keeps payloads small and latency low. Suitable for edge functions and serverless handlers that want country awareness without paying for a full geolocation provider.

Call GET / from the user's request context and read the `country` field from the JSON response

Compliance Country Gating

Enforce geographic restrictions for regulated content, embargoed regions, or per-region features by checking the IP's country code before serving a request. Use the path-based lookup when the IP comes from an upstream proxy header rather than the direct caller. Returns only the country code, so downstream code stays simple.

Read the X-Forwarded-For header, call GET /{ip}, and reject the request if the country code is in a configured embargo list

Bulk IP Triage

Score a backlog of suspicious IPs (server logs, abuse reports, signup forms) by country in a single POST. The batch endpoint accepts a list of IPs and returns the country code for each, so a fraud or security workflow can attach country context to every record without sending one request per IP.

Submit a list of 100 suspicious IPs to POST / and tag each log line with the resolved country code

AI Agent Geo-Context

Give an AI agent country awareness when it processes web requests, support tickets, or signup events. Through Jentic, the agent searches for 'look up country from IP' and gets a structured operation it can call without any credential setup. Because country.is is auth-free, the integration is essentially zero-config.

Use Jentic to search 'look up country from IP', load the schema for GET /{ip}, and execute it with the user-supplied IP

Key Endpoints

4 endpoints — jentic publishes the only available openapi specification for country, keeping it validated and agent-ready.

Why Jentic?

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

Setup

Wiring Country.is by hand means coding your own requests against its api.country.is host for IP-to-country lookups. Through Jentic you install once, import Country.is from the API Directory, and your agent calls it.

Permission scoping

Country.is is a read-only IP lookup where the IP is a value in the path, not a permissionable resource, so scope by operation: limit the agent to the operations it needs, such as looking up the country for an IP address. You choose the operations it may call, so it stays limited to that lookup.

Credential isolation

Country.is takes no credential to call; Jentic still runs it through your own Jentic One instance so nothing sensitive enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'find the country for this IP address', and Jentic returns the matching Country.is operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Country API through Jentic.

Why is there no official OpenAPI spec for Country?

country.is does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Country via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the country.is API use?

country.is requires no authentication. All four endpoints are public and return a JSON object containing only the ISO 3166-1 alpha-2 country code. When called via Jentic, no credential is provisioned for this API.

Can I look up a specific IP address with country.is?

Yes. Send GET /{ip} with the IPv4 or IPv6 address as the path parameter. The response is `{"ip": "...", "country": "US"}`. For multiple addresses in a single request, POST a JSON list of IPs to /.

What are the rate limits for country.is?

country.is does not publish a hard rate limit, but the service is run as a free public utility and aggressive use will be throttled at the network layer. For high-volume workloads, cache the country code per IP and consider falling back to a paid provider.

How do I integrate country.is with an AI agent through Jentic?

Search Jentic for 'look up country from IP', load the schema for GET /{ip}, and execute it with the IP you want to resolve. Because country.is needs no auth, the only thing Jentic returns is the response payload.

Does country.is return city or region information?

No. country.is intentionally returns only the country code. For city, region, or ISP-level enrichment, use a richer geolocation API like ipinfo, ipstack, or ipgeolocation.io.

Can I limit what my agent is allowed to do with the country.is API?

Yes. Because you run Jentic One yourself, your own rules decide which country.is operations the agent may call, and country.is is a read-only IP lookup where the IP is just a path value rather than a permissionable resource, so you scope it by operation. You can allow only the operations the agent actually needs, such as resolving the caller's country with GET / or looking up a specific IPv4 or IPv6 address with GET /{ip}, while withholding the batch POST / or the GET /info service route. Since the API takes no credential, the operations you grant are the only control surface, and the agent stays limited to exactly those lookups.

For Agents

Look up the country for one or many IP addresses with no authentication required. Returns the ISO 3166-1 alpha-2 country code per IP.

Use for: I need to find the country of a given IP address, Look up the caller's country code without authentication, Batch resolve a list of IPs to country codes, Check whether a visitor is in a specific country before showing content

Not supported: Does not return city, region, ISP, or timezone - use for IP-to-country code lookup only.

Jentic publishes the only available OpenAPI specification for Country, keeping it validated and agent-ready. country.is is a free, no-auth IP-to-country lookup service exposed as a small REST API with four endpoints: a caller-IP lookup, a path-based single-IP lookup, a batch POST endpoint, and a service info route. It returns just the ISO 3166-1 alpha-2 country code for an IP address - nothing else - which makes it ideal for lightweight geolocation routing, fraud filtering, or compliance gating without standing up a paid geolocation account.
