When APIs Break the AI Agent Model — and How to Adapt

Updated: 3 hours ago

Agentic AI has opened new doors for automation in logistics. But many organizations are discovering an inconvenient truth: most logistics APIs were never designed to be used by an AI agent.


From deeply nested data structures to inconsistent parameter naming, legacy and 3rd-party APIs can pose significant challenges to agent adoption.

In this article, we break down the core incompatibilities between typical logistics APIs and agentic AI, and how to adapt your systems to overcome them.

Legacy and 3rd-party APIs can pose challenges to AI agent creation.
Understanding API incompatibilities is crucial for effective AI implementation in logistics.

Why Agents Struggle with Logistics APIs


1. Too Many Parameters


Many shipping APIs have 50-200+ parameters required for a single call. Some are conditional or interdependent:


  • Accessorial codes based on freight class

  • Time windows, hazmat flags, equipment types

  • Nested contact info, addresses, package specs


LLMs cannot reliably generate deeply structured JSON without strict constraints. The chance of missing or hallucinating a key field grows quickly.


2. Nested or Inconsistent Schema Design

APIs often include deeply nested structures like:

JSON

{

  "shipment": {

    "origin": {

      "address": { "line1": "..." }

    }

  }

}


Agents do better with flat, consistently named fields. Even minor schema inconsistencies (e.g. zipCode vs postal_code) introduce failure risk.


3. Lack of Metadata


APIs rarely include usable descriptions of parameters. Without documentation or examples, agents cannot infer what values are expected.


4. Unvalidated Input


Agents may generate values that look plausible but are invalid (e.g. incorrect date formats, misspelled service levels). Without input validation, these issues cause silent failures.


5. No Dry-Run or Validation Mode


Many APIs do not support a dry-run flag to test a call without executing it. This makes agent experimentation risky in production.


How to Adapt APIs for Agentic Use


1. Wrap Complex APIs in Simplified Tool Interfaces


Create internal Lambda functions or microservices that:


  • Flatten the input structure

  • Hide conditional logic

  • Translate human-friendly options into API codes


This is much easier for agents to reason about than full booking schemas.


2. Use JSON Schema or OpenAPI Descriptions


Give agents structured metadata:


  • Describe each parameter with examples

  • Define allowed types and enums

  • Set required vs optional fields


This helps agents auto-complete tool inputs correctly.


3. Add a Validation Mode


Before committing to a real booking, allow a "validation only" mode that checks inputs and returns errors without executing side effects. This is crucial for safe agent experimentation.


4. Normalize Field Names and Data Models


Standardize naming across tools:


  • origin_zip, not origZip, OriginZip, zipFrom

  • Use consistent units (e.g. lbs, inches, USD)


Agents struggle when the same concept is expressed differently across systems.


5. Log and Inspect Tool Failures


Agents need observability:


  • Log all input/output

  • Flag unexpected tool results

  • Use retries or fallbacks when necessary


How Our Platform Helps


We know logistics APIs can be inconsistent, overloaded, and hard to work with. That’s why our platform:


  • Provides pre-built wrappers for carrier and TMS APIs

  • Supports flat tool interfaces with descriptions

  • Handles data mapping and transformation for agent-facing tasks


As agentic AI adoption grows, we offer the infrastructure to safely expose even legacy systems to intelligent automation.


Conclusion

Agentic AI can be powerful, but only if the tools it uses are understandable and reliable. Many logistics APIs were built for engineers, not AI.


By wrapping and adapting these APIs with simpler, normalized, and documented interfaces, you can unlock agent compatibility without rewriting your stack.
