Historical quarterly earnings surprises for a US-listed company — reported (actual) EPS vs the analyst consensus estimate, the absolute surprise, and the surprise percentage, for the most recent quarters (newest first). Pass ticker (optionally limit). Tells you whether a company has been beating or missing expectations. Data by Finnhub.
/api/stocks/earnings-surprisesPAYMENT-SIGNATURE.The earnings surprises API is a pay-per-call stocks endpoint built for AI agents and autonomous software. Historical quarterly earnings surprises for a US-listed company — reported (actual) EPS vs the analyst consensus estimate, the absolute surprise, and the surprise percentage, for the most recent quarters (newest first).
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in earnings surprises data source for an agent tool-use loop, an MCP host, or a backend that needs stocks data on demand without onboarding to yet another vendor portal.
