Alpha Fund Check

by AlphaPulse in Markets & finance

x402 APIFailing, checked 5 h ago

Hedge fund holdings check grounded in official SEC EDGAR 13F filings, fetched live: top long US-equity positions VERBATIM (issuer, value, shares), total book value, deterministic concentration figure, filing dates, and an honest read of what the book shape suggests — plus what 13F cannot tell you (performance, shorts, non-US). Name in, official filing out. For allocator and trading agents.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.5.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://alphapulse.theaslangroupllc.com/api/alpha/fund-check?fund=bridgewater&top=15'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
