Do not use to pick among more than two options (/v1/random/pick) or to order a list (/v1/random/shuffle). No API key, no account.

US consumer-demand signal (retail sales)

Use when an agent must decide whether to write to an address, or clean a list before sending: it scores one email 0-100 with a verdict (ok, risky, disposable, undeliverable, invalid) and the evidence under it: every point lost is itemised with the field that proves it. 12,141 disposable domains from two maintained open lists pinned to a commit, 4,897 free providers, 1,018 role names, typo fix (gmial.com > gmail.com), live MX/SPF/DMARC. No SMTP probe, no API key.

French company search and company lookup by name or SIREN in the official French company registry (INSEE Sirene / INPI RNE open data). Name search returns the top 10 matches with identity, SIREN, NAF code, city and active/ceased status, plus a score_confiance (0-1 match confidence) that helps disambiguate homonyms. The entry point to official data and company data on France: resolve a trading name to its SIREN identifier before pulling the full company profile, filings or financials.

Use when an agent has to decide whether a wallet can pay before building a transaction: the native coin balance (ETH, MATIC...) of any address on Base, Ethereum, Polygon, Arbitrum or Optimism, returned both as wei (exact integer string) and as ether, with the chain it was read on. Do not use for token balances (/v1/evm/erc20-balance) or for a whole-wallet view (/v1/evm/portfolio). Flat price, no rate limits, no API key, no account.
