How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the email addresses extracted from the input text. The response is additionalProperties:true, so the exact field names may vary, but expect a list or array of discovered email strings found within the provided text.
Example use cases
Lead harvesting from scraped pages
“I scraped the HTML content of a company's contact page — can you extract all the email addresses out of this raw text for me?”
Email extraction from legal documents
“Here's the full text of a contract with several parties listed — can you find and pull out every email address mentioned in it?”
Contact mining from mailing list archive
“I have a long archive of mailing list messages pasted as plain text — please extract all the unique email addresses from it.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/emails/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call ($0.001 USDC) solution to extract email addresses from arbitrary text without setting up your own regex pipeline. Ideal for autonomous agents that process variable volumes of text and want to avoid fixed subscription costs. Best suited for plaintext or lightly structured content up to 50,000 characters.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- No email addresses found in text — returns empty list
- Malformed input JSON missing required 'text' field — 400 error
- Payment failure via x402 protocol — 402 response before processing
- Obfuscated emails (e.g. 'user at domain dot com') may not be extracted
