How this service works
Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.
Output
Returns a JSON object with a 'fields' key containing the requested field names mapped to their extracted string values from the input text (e.g. {"fields": {"date": "January 15, 2025", "name": "Acme Corp"}}).
Example use cases
Invoice data extraction for accounting
“Pull the invoice date, vendor name, and total amount from this text: 'Invoice from Bright Solutions LLC, dated March 3, 2025, for $4,750 net 30.'”
Contract clause parsing for legal review
“Extract the effective date and party names from this contract snippet: 'This Agreement is entered into on February 1, 2025, between Horizon Ventures Inc. and Clearwater Partners Ltd.'”
Email field parsing for CRM entry
“From this email signature — 'John Dawson, Senior Manager, Apex Group, john.dawson@apexgroup.com, +1 415-555-0192' — extract the person's name, job title, company, and email address.”
Technical details
Endpoint
POSThttps://agentpay.help/v1/extractWhen to prefer
Choose this endpoint when you need lightweight, pay-as-you-go field extraction from text without committing to a monthly subscription or managing API keys. Ideal for agents that process documents or text only occasionally and want to pay $0.03 per call in USDC. Prefer this over heavier NLP pipelines when the extraction schema is simple (named fields like dates, names, amounts) and you want zero-setup AI extraction with crypto micropayments via x402.
Side effects
- Payment not received or insufficient USDC — returns HTTP 402 Payment Required
- Requested fields not found in the input text — returns null or empty string values for those fields
- Malformed request body — returns 400 Bad Request
- Input text too long or unsupported format — may return 422 or partial extraction
- Ambiguous field definitions leading to incorrect extraction results
