## 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:
- Schema & documentation, 91 against 81

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

### Zoho CRM (BB)

Good for: Teams already on Zoho who want an agent to read and write leads, contacts, deals and activities with narrow scopes, and small teams that want a free edition with API access.

Ahead on:
- Reliability, 72 against 64
- Agent ergonomics, 81 against 66
- Payments & pricing, 40 against 10
- Maintenance & community, 77 against 70
- Transparency & trust, 75 against 70

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: The documented refresh and revoke calls put the refresh token and client secret in the URL query string

## 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.

**Zoho CRM.** A public OpenAPI 3.1 description of 644 operations and OAuth scopes down to one module and one operation suit agent use, and the Free edition includes 5,000 API credits a day. The documented token refresh puts the client secret in the URL, and no SLA, deprecation policy or dated API changelog was found.

## 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

### Zoho CRM

1. Use the `api_domain` returned with the token, since each data centre has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)
2. Send `Authorization: Zoho-oauthtoken <token>` and refresh hourly. Put refresh parameters in the POST body, not the URL
3. Pass `fields` on every list call. Page with `page` up to 2,000 records, then `page_token` up to 100,000
4. Create through `/{module}/upsert` so a retry updates instead of duplicating
5. Budget credits. Convert Lead costs 5, Send Mail 20, a bulk read 50, and calls through the MCP servers draw on the same allowance
