How this service works
One-call ALLOW, WARN, or BLOCK trade-risk decisions for Base agents, combining contract safety with live DEX liquidity and activity. Paid per result in USDC over x402.
Output
A JSON object containing a 'data' map of extracted field names to typed values, a count of fields found, a list of missing fields, the LLM model used, the source type (text or url), a timestamp, and a truncation flag indicating if the input was cut off.
Example use cases
Invoice field extraction from raw text
“Extract the vendor name, invoice date, and total amount as a number from this invoice text: 'TechSupplies Inc — Invoice #998, issued April 2 2025, amount owed: $12,800.'”
Product detail scraping from a URL
“Fetch this product page and pull out the product name, price as a number, and whether it's in stock as a boolean: https://example.com/products/widget-pro”
Contact info parsing from unstructured email body
“From this email text, extract the sender's name, email address, and phone number: 'Hi, I'm Jordan Lee, reach me at jordan.lee@company.com or call 555-867-5309.'”

Endpoint
GEThttps://base-intel-api.jakemaxsigal.workers.dev/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to turn unstructured text or a live web page into typed, named fields in a single API call without building a custom parsing pipeline. It is ideal for document parsing (invoices, receipts, emails), lightweight web scraping into structured JSON, and any scenario where you need LLM-powered extraction billed per-call at $0.02 USDC rather than managing your own model infrastructure.
Side effects
- Missing required 'fields' query parameter returns an error
- Text exceeding 12,000 characters gets truncated (truncated: true in response)
- Ambiguous field names may result in empty or incorrect extractions
- URL fetch failures return an error if the page is inaccessible or paywalled
- Payment not sent or insufficient USDC results in HTTP 402 response
- Schema and fields both omitted causes undefined extraction behavior
