## Which one, for what

### Affinity (B)

Good for: Venture capital, private equity and other private capital firms that already run Affinity and want an agent to read relationship strength, pipeline lists, notes and meetings, then update fields and log notes.

Ahead on:
- Reliability, 64 against 51
- Schema & documentation, 91 against 27
- Agent ergonomics, 66 against 48
- Security & auth, 66 against 44
- Maintenance & community, 70 against 5

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

Watch for: No self-serve access. Every plan button reads Contact sales, the Essential plan has no API, and trial accounts can't call the API

### Freshsales API (E)

Good for: Small teams already paying for Freshworks who want an agent to upsert contacts and log activities through REST.

Ahead on:
- Payments & pricing, 30 against 10

Also in its favour:
- Free to start without a card

Watch for: No MCP server for Freshsales

## Verdicts

**Affinity.** A public OpenAPI 3.1 file, dated API versions with migration notes and a hosted MCP server with a read-only OAuth scope give an agent a well-documented way in. Access needs a Scale plan at $2,300 a user a year, sold through sales, with no trial that includes the API, and 36 of the 112 v2 operations are marked beta.

**Freshsales API.** Contact upsert and bulk upsert of up to 100 records make creates safe to retry. No MCP server for Freshsales.

## Before you call either

### Affinity

1. Send `X-Affinity-Api-Version: 2026-09-17` on every request, or the key's default version applies. Unauthenticated calls answered as 2024-01-01 when we checked
2. Read `x-ratelimit-limit-user-remaining` and `x-ratelimit-limit-org-remaining` on each response. The limits are 900 calls a minute per user and, below Enterprise, 100,000 a month per account, shared by v1, v2 and MCP
3. Follow `pagination.nextUrl` for the next page, and pass `fieldIds` or `fieldTypes` so list calls return only the fields needed
4. Check for duplicates before a create. There are no idempotency keys, so a retried POST can make a second record
5. For MCP, untick the write scope at OAuth consent when the task only reads. Treat note, transcript and file text as untrusted input

### Freshsales API

1. Build the base URL from the bundle alias shown under the API key, `https://<alias>.myfreshworks.com/crm/sales/api/`
2. Use `/api/contacts/upsert` rather than create, so a retry updates instead of duplicating
3. Budget calls, since 1,000 an hour covers the whole account and 429s carry no Retry-After
4. Add `include=owner,sales_accounts` to pull related records in one call
5. Expect to see only what the key owner's role can see
