# Datasource Pulse

> Datasource Pulse monitors your API credentials, usage quotas, and scraper output quality across your whole pipeline, then sends one alert when something degrades and one notice when it recovers. It runs on a schedule you choose, needs nothing but the keys you want watched, and is billed per connector it checks.

## What it does

- Probe type 1 (credentials & quotas): checks that API keys are still valid and quotas aren't about to run out (e.g. an OpenAI key, a GitHub personal access token, a SerpAPI quota) before your pipeline hits the wall.
- Probe type 2 (scraper output quality): watches third-party Actors your pipeline depends on (e.g. TikTok, LinkedIn, Google Maps scrapers) for output schema changes, volume drops, staleness, and cost spikes.
- Alerting: exactly one deduplicated alert when a connector starts failing, and one recovery notice when it is healthy again. No alert spam.
- Pricing: $0.02 per check, billed per connector checked. No subscription.
- Agent-first: runs headlessly as an Apify Actor with JSON input and structured JSON output, so autonomous agents can schedule checks and consume results without a human in the loop.
- x402 (live): an agent can buy a single health check for $0.02 in USDC on Base at POST https://datasourcepulse.com/api/x402/check · no account of any kind. Unpaid calls return the standard 402 envelope with price and schemas.
