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.
Example use cases
Parsing blockchain addresses from forum posts
“I've got a big block of text from a crypto Discord — can you extract every EVM wallet address, URL, and any token amounts mentioned in it?”
Structuring invoice data for payment agent
“Here's an invoice description as plain text — can you pull out the payment amount, currency, due date, and any wallet addresses so I can queue the payment?”
Auditing smart contract deployment notes
“I have raw deployment notes for a contract launch — extract all the dates, EVM addresses, and ETH or USDC amounts so I can verify everything lines up.”
Technical details
Endpoint
POSThttps://mm-agent-utils.gferrigno.deno.net/v1/extract?utm_source=zero.xyzWhen to prefer
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).
Side effects
- 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
