Lightweight relationship CRM (people, companies, groups, deals/custom objects) with a modern REST API: 100-record batch endpoints, search, idempotency keys, Standard Webhooks, async email/phone enrichment on workspace credits, and a hosted MCP; API only on Premium and above. Best for agencies, VCs and founder-led teams that want a simple CRM their agents can write to.
The actions you pay for, as folk prices them.
| Action | Cost |
|---|---|
| Create up to 100 people; each record succeeds or fails on its own | none |
| Update up to 100 people | none |
| Search people with filters (dedupe lookups) | none |
| Create up to 100 companies; a record naming an existing company UPDATES that company (name is the unique key) and its result says so | none |
| Search companies | none |
| Batch-create up to 100 deals or custom objects of one type inside a group. Records are NEVER matched with existing objects: a retried batch creates every object again unless an Idempotency-Key is sent | none |
| Enrich people: async email and/or phone enrichment for up to 500 people (same engine as the app's 1-click enrichment) | Workspace person_enrichment credits, charged per person and per field found; 402 up front if credits cannot cover the maximum possible cost. Our test: 1 credit reserved while running, released when nothing was found (net 0) |
| Credits used and available for each metered feature in the current period (needs contributor role or above) | none |

Per user (all of a user's keys share it): default 600 requests per 1-minute fixed window AND burst 20 requests per 2-second window; rejected requests still consume quota; 429 with Retry-After; IETF RateLimit / RateLimit-Policy headers plus legacy X-RateLimit-* headers.
Windows are fixed and clock-aligned (minute and 2-second); spread to about 10 requests/second. A rate-limited request never runs, so it is always safe to retry. Our hands-on calls returned x-ratelimit-limit: 600, x-ratelimit-limit-burst: 20 and ratelimit-policy "default";q=600;w=60, "burst";q=20;w=2 on every response.

We considered folk when choosing a free CRM for our own team and ruled it out because it has no free plan: the 2-week trial ends with the account blocked unless you upgrade, and API access is listed under the Premium plan.
