ExtractionEntitiesTextCrypto-addressesContacts

Pull structured entities out of any text in one deterministic call (no LLM): emails, URLs (+ domains), phone numbers (E.164-normalized when a country code is present), EVM addresses (EIP-55 checksum validity flag), tx hashes, Bitcoin/Solana-style addresses, IPv4, ISO and common dates, money amounts with currency, percentages, hashtags and @mentions. Each item has its count and first character offset; duplicates merged. Max 500 KB text. Failed calls (4xx) are not settled.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
