Ecommerce Amazon Category Lookup

Amazon Category Lookup

Core Concepts

Browse Amazon category nodes by parent identifier or search category metadata by name.

Core workflow

1. Identify the marketplace, entity identifiers, date range, filters, and requested output.
2. Ask only for missing inputs that materially change the result.
3. Read references/api.json and select the exact package-local script for the required connector, calculation, transformation, or account workflow.
4. Execute the cataloged mode exactly: run local-script operations from this package, and follow this document for agent-guided operations.
5. Validate returned fields and preserve the distinction between source facts, calculations, and recommendations.
6. Save large results through the runtime and present a concise user-facing summary with the artifact path.

Operation Catalog

The machine-readable source of truth is references/api.json. Field-level payload rules remain operation-specific; do not invent identifiers, filters, credentials, or marketplace facts.

API Invocation

Run only the package-local script recorded in the selected operation's upstreamPath. Business/tool operations may use the NexScope proxy; authorization/account operations use their configured Agent/Login service, and third-party connectors use their documented provider endpoint. Never invoke a script from another Skill.

Usage Examples

python scripts/amazon_category_lookup.py --mode lookup '{"marketId":"1","nodeId":"-1"}'
python scripts/amazon_category_lookup.py --mode like '{"marketId":"1","nodeLabel":"Electronics"}'

Use lookup to browse children of a known node and like to search category labels. Read references/api.md for marketplace IDs, parameters, and response fields.

For a cataloged mutation, obtain explicit user approval and then pass both --confirm and --confirm-mutation. Never infer confirmation from an earlier read request.

Runtime configuration

Business/tool operations require NEXSCOPE_PROXY_BASE plus NEXSCOPE_API_KEY; authorization/account operations require the relevant NEXSCOPE_AGENT_* or NEXSCOPE_LOGIN_* base because those proxy routes are not implemented. Third-party connectors require their documented provider configuration. Install optional libraries named by a script only when that operation is selected. Read references/credentials.md and set only the variables required by the selected script. Never pass secrets in command arguments or persist them in output artifacts.

Use only the hosts, credentials, and endpoints implemented by the package-local script and documented in references/credentials.md. Never substitute an undocumented legacy host or expose secret values.

Display Rules

• Keep full JSON in the generated nexscope/<date>/<session>/data/ artifact.
• Show the user the relevant records, assumptions, calculations, and limitations.
• Redact authorization, tokens, cookies, secrets, and passwords recursively.
• Do not treat an HTTP 200 response as success when the response envelope or upstream payload reports a business failure.

Important Limitations

• Do not fabricate marketplace data or silently fill required business identifiers.
• Do not retry a mutation after an ambiguous timeout; query status first.
• Treat legal, compliance, tax, and profitability outputs as decision support, not professional advice.
• Do not claim real-account, sandbox, ZIP-install, or production validation unless that evidence exists.

References

• Read references/workflow.md before executing the domain procedure.
• Read references/api.md for the package contract and examples.
• Read references/testing.md before claiming a validation level.

Privacy and Errors

Treat marketplace, account, product, advertising, order, supplier, and generated-asset data as private. Keep credentials out of payloads and artifacts. Surface HTTP, application-envelope, upstream-business, malformed-response, and unavailable-connector failures distinctly.

Authentication

Set the NEXSCOPE_API_KEY environment variable. If credentials are missing or expire, visit https://www.nexscope.ai/help/skills-external-access?co-from=skillNS to top up credits.
