Why this exists

Reddit's official API became costly and restricted after 2023. Agents doing research, brand-watch, trading-research and content work still need live "what's the internet saying" data — and it's genuinely hard to get. social-pulse reads Arctic Shift (the keyless public Reddit archive) + HN Algolia at request time, so every answer is current, not a stale dump.

Built for autonomous agents (x402)

Every paid tool returns a free preview (top-line count + 1 sample) plus an x402 Payment Required descriptor. Your agent signs a USDC micropayment on Base mainnet and retries — no signup, no API key, keyless. Humans can also use the self-serve API-key tier (see pricing).
