Security
Does access stay within the defined limits?
Investigates exposures that could compromise information and operations.
R/Pulse API Resilience Core
Your APIs change. Validate that they stay reliable.
R/Pulse ARC tracks your APIs over time and points validations at what changed. When it finds a risk, it gathers evidence to guide the fix. After the fix, a new evaluation checks whether the behavior was resolved.

APIs change faster than teams can revalidate them
An API can respect the business rules today and stop respecting them after the next change. New endpoints, contract changes, integrations and business rules widen the conditions that need to be checked.
When coverage doesn't keep pace, teams spend more time choosing what to review, rebuilding scenarios and investigating problems. The gap grows between a change and the discovery of behavior outside what was expected.
Illustrative example
Change detectedPOST/api/v1/transfers
| Before the change | After the change | |
|---|---|---|
| Transfer amount | $8,000 | $8,000 |
| Allowed limit | $1,000 | $1,000 |
| Result | Operation rejected | Operation processed |
Put the evolution of your APIs to the test
R/Pulse ARC (API Resilience Core) is our continuous API validation module. Starting from the specification, it builds a validation baseline and identifies relevant changes as the API is updated. What changed guides new evaluations, so coverage keeps up with operations.
ARC validation flow
Understands the API
Reads the specification and sets the baseline for evaluating different risk dimensions.
Identifies changes
Recognizes relevant changes to endpoints and contracts and points validation at what needs to be reviewed.
Evaluates and presents risks
Creates focused validations, records the behavior found and gathers evidence for reproduction and treatment.
Verifies the fix
After treatment, a new evaluation checks whether the scenario that caused the risk was resolved. Coverage keeps following new changes.
An API can respond correctly. Even so, it can fail where it matters most.
ARC evaluates API reliability across five dimensions that cover technical behavior and the consequences for operations.
Availability
Does the operation stay stable under unexpected conditions?
Identifies risks of interrupting services and critical journeys.
Integrity
Are data and business rules preserved?
Points to behavior that could produce improper transactions or inconsistencies.
Performance
Does the API sustain the performance the business requires?
Identifies degradations that affect experience, productivity and scale.
Compliance
Does the behavior meet the requirements that govern the operation?
Investigates deviations and gathers evidence useful for checks and audits.
Results that guide the fix and confirm the treatment
When it identifies a risk, ARC shows the observed behavior, gathers reproducible evidence and indicates its treatment priority. Engineering, QA, Platform and AppSec can work on the same concrete case, with less effort spent rebuilding what happened.
After the fix, a new evaluation checks whether the risk remains. For leadership, this gives visibility into what was found, what was treated and which scenarios have already been re-evaluated.
What the results help answer:
- What changed, and which behavior left the expected path?
- Which risk needs attention first?
- Did the fix resolve the scenario found?
Finding
- Observed behavior
- Reproducible evidence
- Priority

AI-assisted fix support
Validation that keeps up with the APIs your operation depends on
ARC makes the most sense when APIs change often, support relevant processes and require recurring re-evaluation without growing manual effort at the same rate.
Critical APIs that keep changing
When a change could affect customers, transactions, partners or core processes.
Releases, integrations and migrations
When the new version needs to show that contracts and behaviors are still adequate.
Teams with recurring validation
When preparing scenarios, reproducing risks and verifying fixes takes up Engineering, QA, Platform and AppSec capacity.
Frequently asked questions about R/Pulse ARC
What is continuous API validation?
It's keeping validation coverage aligned with how APIs change. In ARC, relevant changes direct new evaluations to investigate whether the expected behavior is still respected.
How does ARC identify changes?
ARC follows the evolution of the API specification and identifies relevant changes to endpoints and contracts. These changes guide the creation of focused validations.
What does the team receive when a risk is found?
The risk comes with the observed behavior, evidence for reproduction and a priority indication, supporting analysis and treatment by the responsible teams.
How does ARC verify a fix?
After treatment, the scenario related to the risk goes through a new evaluation. ARC checks whether the identified behavior still occurs before considering the risk treated.
When your API changes, how long does it take to know it's still reliable?
See how ARC points validations at changes, presents the risks found and verifies treatment.
