Guide

Credits reference

Every API and MCP call consumes credits. Credits reset monthly with your plan. The meta.credits field on every response shows what was charged and your remaining balance.

How credits are counted

Feed endpoints charge per record returned

A call to /funding/latest with limit=20 that returns 20 records costs 20 credits — not 1. Set limit carefully.

MCP calls cost the same as direct API calls

The MCP server maps directly to the underlying API endpoints. get_company_profile costs 5 credits, same as calling /company directly.

Pagination is not free

Each page of results is charged separately. Fetching 100 records across 5 pages costs 100 credits, not 5.

Errors do not consume credits

4xx and 5xx responses do not charge credits. Only successful 200 responses are billed.

Monthly usage estimates

Common workflows and their approximate monthly credit cost.

Daily feed pull (50 records/day)

50 records × 30 days = 1,500 credits/month

Solo plan (200 credits) covers ~4 days. Growth plan handles this comfortably.

Enrich 100 qualified leads/month

100 × (1 feed + 5 company + 2 jobs) = 800 credits

Solo plan covers ~25 leads fully enriched. Growth covers 250.

Full GTM engine (feed + enrich + signals)

50 records/day × 30 days + 500 enrichments = 5,500 credits

Scale plan (10,000 credits) handles this with headroom.
