NEXUS Document Extractor

NEXUS Agent-as-a-Service on Cardano

When to use

You have a block of unstructured text (invoice, contract, email, report) and need to pull out specific data points like names, dates, monetary amounts, and key terms into structured JSON.

What makes this different

Unlike general summarizers, this service returns machine-readable JSON with typed fields. Ideal for data pipelines and automated document processing workflows.

Steps

1. Prepare your input payload as JSON.
2. Send a POST request to the NEXUS endpoint with X-Payment-Proof header.
3. Parse the structured JSON response.
