Why Greenwood

The same data Bloomberg uses.
At machine prices.

01

Public source, private edge

All data comes directly from SEC EDGAR and the House Clerk — legally mandated public disclosures. We process, score, and structure it so you don't have to.

02

Proven performance

ONON +21%, FLUT +9.7%, AMRZ +3.3% — all within days of EDGAR signals firing. The insider buying thesis works. We just surface it faster.

03

Agent-native pricing

$0.002 per query. Traditional financial data APIs charge $99–$999/month. x402 micropayments make per-query pricing viable for the first time.

04

No lock-in

No subscription. No account. No API key. Deposit USDC, query what you need, pay only for what you use. The x402 protocol handles everything.
