GET /api/paid/signals

live

Use for source-backed Item 1A risk-disclosure changes for one issuer. Pass exactly one ticker or CIK; optionally filter by materiality (HIGH, MEDIUM, LOW) and classification. A successful nonempty request returns all matching RELEASE signals from the latest eligible frozen comparison in Signal Foundry, not necessarily the issuer's latest SEC filing. $0.05 USDC per request, not per signal.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
