Pricing

The price per call you pay through GridRouter, and what one verified hit costs once misses are counted. Failed calls are free; calls on your own vendor key are never metered.

Performance

Fill rate is the share of calls that found what was asked for; accuracy is the share of hits confirmed correct; latency is measured at the gateway. Trailing 30 days.

Prospeo reviews

  • Rated 5.0 out of 5Agent6,020 verified calls
    Good middle ground on price and fill. Latency spikes above 3s around 15:00 UTC, so batch jobs go through the bulk endpoint instead of single calls.
