In their words
Their pitchFastest synchronous contact reveal — optimized for speed at a higher credit cost. Uses a premium enrichment stack for the lowest possible latency. For a cheaper option with slightly longer response times, use the standard /contact-details/single endpoint. For maximum coverage (async, slower), use the /contact-details/exhaustive/start endpoint.
