Install Jentic One Beta

Connect the Newton API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Newton 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fnewton.vercel.app%2Fnewton" | 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%2Fnewton.vercel.app%2Fnewton" | 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 Newton API.

Simplify or factor an algebraic expression via GET /simplify/{expression} and GET /factor/{expression}

Compute derivatives and integrals through GET /derive/{expression} and GET /integrate/{expression}

Find roots and tangent lines of a function via GET /zeroes/{expression} and GET /tangent/{expression}

Calculate the area under a curve with GET /area/{expression}

Use Cases

Patterns agents use Newton API for, with concrete tasks.

★ Math Helper for Chat Agents

AI assistants embedded in chat surfaces forward math questions to Newton instead of computing them with a language model. The agent extracts the expression, calls the appropriate endpoint - GET /derive for derivatives, GET /factor for factoring - and returns the structured result. This avoids the well-known failure modes of language models doing arithmetic and gives a deterministic, citable answer.

Compute the derivative of 2x^3 + 5x by calling GET /derive/2x%5E3+5x and return the simplified result

Homework and Tutoring Tool

Education platforms back their show-your-work tutoring features with Newton. The platform asks the student for an expression, sends it to GET /simplify or GET /factor, and renders the response next to the student's manual steps so they can compare. Because every operation is a single GET request with the expression in the URL, integration is trivial and the response is purely the math result with no extra metadata.

Show the factored form of x^2 - 9 by calling GET /factor/x%5E2-9 and display the result alongside the student's working

Notebook and Spreadsheet Add-In

Productivity tools embed Newton calls in spreadsheet cells or notebook code so a non-coder can compute symbolic math without installing a CAS. A single HTTP call returns the integral or root, and because the API has no authentication and no rate-limit headers in the spec, lightweight scripts and educational tools can use it directly. For high-volume or commercial workloads a heavier engine is appropriate.

Compute the integral of x^2 from a notebook cell by calling GET /integrate/x%5E2 and return the antiderivative

Agent-Assisted Math Reasoning

An AI agent uses Newton through Jentic to verify the math in its own reasoning chain. When the agent generates a step like 'so the derivative is 6x', it calls GET /derive/{expression} to confirm before continuing, catching arithmetic slips before they propagate. Jentic supplies the operation schemas so the agent picks the right endpoint per math type.

Before stating a derivative result, call GET /derive on the original expression and confirm the response matches the agent's stated answer

Key Endpoints

15 endpoints — newton is a free, no-auth math micro-service that performs symbolic and numerical calculations from a string expression in the url path.

Why Jentic?

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

Setup

Wiring Newton by hand means URL-encoding each math expression into the path, choosing among fifteen operation endpoints, and parsing the JSON result yourself. Through Jentic you install once, import the Newton API from the API Directory, and your agent calls it with no key to manage.

Permission scoping

Newton is a public, unauthenticated math service with the expression in the URL path (/derive/{expression}), so scope your agent by operation: limit it to the operations it needs, such as simplify, derive, or integrate, and leave the rest out of the allowed set. You choose which of the fifteen operations it may call.

Credential isolation

Newton needs no credential, so there is nothing for Jentic One to store or inject; the agent reaches it through the same execution flow as authenticated APIs, with credential handling effectively a no-op.

Intent-based discovery

Agents search Jentic by intent such as 'compute the derivative of an expression' or 'factor a polynomial', and Jentic returns the matching Newton operation with its path parameter schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Newton API through Jentic.

What authentication does the Newton API use?

The Newton API has no authentication - every endpoint is a public GET with the expression in the URL path. Through Jentic the operations are still wrapped with the standard discover-load-execute flow, but there is no credential to manage in the vault for this API.

Can I compute integrals with the Newton API?

Yes. GET /integrate/{expression} returns the antiderivative for the supplied expression. URL-encode special characters such as the caret for exponents. Pair it with GET /area/{expression} when a definite area calculation is needed instead.

What are the rate limits for the Newton API?

The OpenAPI spec does not declare rate limits and the service is hosted on Vercel as a free micro-service, so callers should treat it as best-effort and back off on errors. For production workloads, an agent should batch or cache calls rather than hammering it from a tight loop.

How do I verify a derivative with the Newton API through Jentic?

Search Jentic for 'compute the derivative of an expression', load the GET /derive schema, and execute with the expression in the path parameter. The response is a small JSON object containing the result, which the agent can compare against its own answer.

Does the Newton API handle symbolic constants like pi or e?

Newton parses common math syntax including pi and e, plus standard operators and the trig functions. Expressions are URL-encoded path parameters, so an agent should encode characters like '+', '^', and spaces before sending the request.

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

Yes. Because you run Jentic One self-hosted, your own rules decide which of Newton's fifteen operations the agent may call, so you can allow just the ones it needs, such as GET /simplify, GET /derive, or GET /integrate, and leave the rest out of the allowed set. Newton is a public, unauthenticated service that takes the expression in the URL path, so there is no key to manage and scoping is done purely at the operation level. This keeps the agent restricted to the specific math functions you approve rather than the whole endpoint list.

For Agents

Compute symbolic math results - simplify, factor, derive, integrate, find zeroes, evaluate trig - from an expression in the URL path. No authentication required.

Use for: Find the derivative of x^2 + 3x, Integrate sin(x) from 0 to pi, Simplify the expression 2x + 3x - x, Factor the polynomial x^2 - 4

Not supported: Does not handle linear algebra, statistics, plotting, or LaTeX rendering - use for single-expression symbolic and numerical math operations only.

Newton is a free, no-auth math micro-service that performs symbolic and numerical calculations from a string expression in the URL path. The 15 GET endpoints cover algebraic manipulation (simplify, factor), calculus (derive, integrate, area, tangent), root finding (zeroes), trigonometry (sin, cos, tan plus inverses), and basic functions (abs, log). Each endpoint takes the expression as a path parameter and returns a JSON object with the result.
