# mm-agent-utils Entity Extractor

> mm-agent-utils Entity Extractor is a paid API for AI agents from mm-agent-utils.gferrigno.deno.net, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Deterministically extracts structured entities (dates, amounts, EVM addresses, URLs, emails) from up to 50k characters of text

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 mm-agent-utils-entity-extractor-893a1d3c -d '<json body>'
```

Example prompt: Can you pull out all the EVM addresses, dates, and USDC amounts from this text for me? Here it is: 'Send 12.5 USDC to 0xd8dA... by 2026-10-01.'

## When to prefer this

Choose this endpoint when you need deterministic, structured extraction of blockchain-relevant entities (EVM addresses, crypto amounts, dates) from arbitrary text — especially in Web3 agent pipelines where consistency matters more than ML-based NER. Ideal when the text is up to 50k chars and you need reliable counts alongside the extracted values. Prefer over general-purpose LLM extraction when you want reproducible, non-hallucinated results at low cost ($0.001/call).

## Known failure modes

- Text exceeds 50k character limit — request will be rejected or truncated
- Ambiguous or informal amount formats (e.g. 'a couple bucks') may not be extracted
- Non-checksummed or abbreviated EVM addresses may be missed
- Payment failure if USDC balance insufficient for $0.001 per-call fee
- Malformed JSON input returns a 4xx error
- Dates in unusual locale formats (e.g. '1st of October') may not be detected

## How this service works

Tiny pay-per-call utilities for agents on Base: wallet vetting, x402 endpoint linting, deterministic entity extraction.

## Output

A JSON object containing arrays of extracted dates (ISO format), EVM addresses, and monetary amounts (with unit and value), plus a counts object summarizing how many URLs, emails, and EVM addresses were found in the input text.
