How this service works
Lightweight text utilities for AI agents: key-sentence digest, sentiment label, and entity extraction (email, URL, EVM/Solana addresses). Pay-per-request in USDC on Base and Solana via x402. No API keys, no accounts, no signup.
Output
A JSON object with four arrays: 'emails' (extracted email addresses), 'urls' (extracted URLs), 'evm' (Ethereum/EVM wallet addresses), and 'solana' (Solana wallet addresses) — all found within the supplied text. Arrays are empty if no entities of that type are detected.
Example use cases
Crypto address harvesting from announcements
“Pull out every EVM and Solana wallet address from this airdrop announcement post: 'Send funds to 0x742d35Cc... or GsbwXfJi... for the giveaway, questions to airdrop@defi.io'”
Lead extraction from raw email body
“Extract all email addresses and URLs from this raw email body I just received so I can log them as leads: 'Reach our sales team at sales@acme.com or support@acme.com, and check out our new page at https://acme.com/new-product'”
Link and contact audit in user-submitted content
“Scan this user-submitted forum post for any emails, URLs, and blockchain addresses — I need to know what external references it contains before we approve it for publication: 'Join our Discord at https://discord.gg/xyz, DM me at user@mail.com, tip jar: 9xQdKBnYm...'”
Technical details
Endpoint
GEThttps://kassa-402.annushka1190.workers.dev/v1/entitiesWhen to prefer
Choose this endpoint when you need lightweight, no-signup entity extraction from unstructured text — especially when you need to identify crypto wallet addresses (EVM or Solana) alongside standard contact entities like emails and URLs. Ideal for agents processing blockchain-related content, user submissions, or messages where wallet addresses may appear alongside conventional contact info. Pay-per-request USDC pricing on Base/Solana via x402 makes it suitable for sporadic, on-demand agent workflows without account management overhead.
Side effects
- Missing 'text' query parameter returns an error
- Empty or whitespace-only text may return all empty arrays
- Very long text may exceed worker limits
- Payment failure via x402 returns 402 status blocking the request
- Non-UTF-8 or malformed input may cause parse errors
