Agentic API Testing

Agentic API penetration testing

Point Planck Operator at your API. It parses your OpenAPI spec, tests every documented operation the way an attacker would — BOLA, BFLA, broken auth, mass assignment, injection, across user roles — and proves each finding with the exact request and response. Continuous, spec-driven, and safe against production.

How A Scan Runs

From spec to proven findings, in five steps

Setting up an API engagement takes minutes. You define the target and scope; the agent does the rest and streams its work live.

Live

Watch the agent test every operation

This is the operator console as a real API scan runs — parsing the spec, testing operations, chaining a leaked token, and confirming each finding.

Coverage

What we test — the OWASP API Security Top 10

The agent maps to the 2023 OWASP API Security Top 10 and extends it with classic injection on every parameter your spec exposes.

API1

Broken Object Level Authorization

The number one API risk. We request other users’ objects by ID across roles to prove BOLA and IDOR reads and writes.

API2

Broken Authentication

Forgeable or non-expiring tokens, weak JWT handling, and unauthenticated endpoints that should require a session.

API3

Object Property Level Auth & Mass Assignment

Setting fields you should not be able to set, and reading properties that should never leave the server.

API4

Unrestricted Resource Consumption

Missing rate limits and unbounded queries that let one caller exhaust or bill your infrastructure.

API5

Broken Function Level Authorization

Calling admin or privileged functions as a lower-privileged role, tested by replaying one role’s requests as another.

API6–10

Business flows, SSRF, misconfig, inventory

Sensitive business-flow abuse, server-side request forgery, misconfiguration, shadow and deprecated endpoints, and unsafe upstream consumption.

The Differentiator

Cross-account testing scanners cannot do

Most serious API breaches are authorization failures, not injection. Finding them requires understanding who should be allowed to do what — something a pattern-matching scanner has no concept of.

You give Operator one bearer token per user type. With two or more, it sends one role’s requests as another and watches what comes back: another tenant’s records, an admin-only function, a resource that should have returned 403. That is BOLA and BFLA, proven with the exact cross-account request and response.

  • One token per role — analyst, admin, tenant A, tenant B.
  • Requests replayed cross-account to expose broken object and function authorization.
  • Read-only by default — only GET, HEAD, and OPTIONS, safe against production.
  • Scope-locked to your verified domain and base URL; excluded operations are never touched.
Proof, Not A List

What a confirmed API finding looks like

Every finding is grouped by severity and ships with the request that triggered it, the response that confirms it, and a CVSS v3.1 vector.

Critical

Unauthenticated endpoint leaks admin credentials

An endpoint reachable without a session returns management-panel admin credentials in its response — a full compromise path, confirmed with the exact unauthenticated request.

High

Splash endpoint issues valid JWT for any device

An unauthenticated operation mints a valid JWT for an arbitrary device_id with no attestation, enabling unlimited account creation. Reproduced and rated.

Agentic vs Manual

Continuous breadth, human depth

Agentic API penetration testing gives you continuous, spec-driven coverage across every operation, run as often as your API ships. Our manual API security testing adds a senior tester who goes deep on business-logic abuse and chained flaws unique to your product.

They are complementary, not rivals. Most teams run the agent continuously and bring a human in for depth on the highest-risk flows. Both map to the same standards and deliver the same proof-based findings. See how the category works in our guide to agentic pentesting.

  • Agentic — continuous, every operation, run on every change.
  • Manual — senior human depth on business logic and chained abuse.
  • Same standards — OWASP API Top 10, CVSS v3.1, proof attached.
  • Delivered where you work — Jira, GitHub, Slack, or export.
Continuous, Not One-Off

Test on every deploy, not once a year

A one-off API pentest is stale the day after it ships — your next release adds an endpoint it never saw. Agentic testing runs on every change, so coverage keeps pace with your API instead of a calendar. There is no per-test fee that punishes you for testing more often; you test as often as you deploy.

It also finds the class of bug scanners cannot: object and function level authorization. See how we keep noise near zero in reliability and accuracy, and where the market is heading in our state of agentic pentesting report.

  • Run on every change — wired into CI/CD, not a yearly calendar event.
  • No per-test fee — test as often as you ship, without scaling cost per run.
  • Every operation, every time — new endpoints are tested the moment they appear in the spec.
  • Proof, not noise — each finding reproduced before it reaches your tracker.
FAQ

Common questions about API penetration testing

What is agentic API penetration testing?

Agentic API penetration testing uses an autonomous AI agent to test an API the way an attacker would. It parses your OpenAPI or Swagger spec, enumerates every documented operation, reasons about which are abusable, and tests them for authorization, authentication, and injection flaws across multiple user roles. It reproduces each finding with the exact request and response before reporting it, so you receive proven, exploitable issues rather than a list of unverified alerts.

How is it different from a DAST tool or API scanner?

A scanner matches known patterns on individual requests and cannot understand your business logic. An agent reasons across operations: it sends one role’s requests as another to find broken object and function level authorization, chains a leaked token into a privileged call, and confirms impact by carrying the attack through to effect. Scanners flag; the agent proves.

What does it test?

The OWASP API Security Top 10: broken object level authorization (BOLA), broken authentication, broken object property level authorization and mass assignment, unrestricted resource consumption, broken function level authorization (BFLA), unrestricted access to sensitive business flows, server-side request forgery, security misconfiguration, improper inventory management, and unsafe consumption of APIs, plus classic injection on every parameter the spec exposes.

Do you test authorization flaws like BOLA and BFLA?

Yes, and they are the core of the engagement. You provide one bearer token per user type; with two or more roles the agent sends one role’s requests as another to detect broken object level authorization (BOLA) and broken function level authorization (BFLA), the cross-account and privilege boundary failures that scanners cannot find because they have no concept of who should be allowed to do what.

Is it safe to run against a production API?

Yes. The scan defaults to read-only, sending only GET, HEAD, and OPTIONS, which is safe against production. You can opt in to writes (POST, PUT, PATCH) or to writes plus DELETE for disposable test data. Scope is locked to your verified domain and the base URL you set, every request stays under that base, and you can exclude any operation before launch.

What do you need to start an API scan?

A verified domain, an API base URL under it, and your OpenAPI or Swagger spec (uploaded, linked, or pasted). Optionally, one bearer token per user role to unlock authenticated and cross-account testing, and any global headers such as an API key. The agent parses the spec, lists the operations in scope, and only tests what you include.

How is this different from your manual API security testing?

They are complementary. Agentic API penetration testing gives you continuous, spec-driven breadth across every operation, run as often as your API changes. Manual API security testing adds a senior human tester who goes deep on business-logic abuse and chained flaws unique to your product. Most teams run the agent continuously and bring a human in for depth on the highest-risk flows.

Will it flood us with false positives?

No. Every finding is reproduced before it is reported, with the exact request and response that prove it, so what reaches your tracker is confirmed and exploitable rather than a queue of maybes. Anything the agent cannot reproduce is discarded, and you can route any finding through a senior practitioner for a human signature before it lands.

Definition

What is agentic API penetration testing?

Agentic API penetration testing uses an autonomous AI agent to test an API the way an attacker would. From your OpenAPI or Swagger spec, the agent enumerates every documented operation, reasons about which are abusable, and tests them for authorization, authentication, and injection flaws — across multiple user roles at once. Every finding is reproduced with the exact request and response before it reaches your report, so you get proven, exploitable issues instead of a queue of unverified alerts.

Spec-driven

Every operation, tested

The agent parses your spec, lists each operation in scope, and tests the ones you include. Only documented operations, no blind fuzzing of endpoints that do not exist.

Cross-account

Authorization, the hard part

Give it one token per role and it sends one role’s requests as another — the BOLA and BFLA failures a scanner can never reason about.

Proven

Reproduced, not guessed

Each finding carries a working request and response and a CVSS v3.1 vector. Anything the agent cannot reproduce never reaches you.

Get Started

Test every operation your API exposes

Give Operator your spec and a token per role. It will tell you what an attacker can reach — and prove it.
