# Base Intel API — Structured Text & Web Extraction

> Base Intel API — Structured Text & Web Extraction is a paid API for AI agents from base-intel-api.jakemaxsigal.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Extracts structured fields from raw text or a web page URL using LLM inference, returning typed key-value data in a single call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-intel-api-structured-text-web-extraction-d5d0b087
```

Example prompt: Pull the company name, invoice date, and total amount (as a number) from this text: 'Acme Corp — Invoice #4421, dated March 15 2025, total due $3,450.00.'

## When to prefer this

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.

## Known failure modes

- 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

## 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.
