Every plan button reads Contact sales, the Essential plan has no API, and trial accounts can't call the API\n\n### Salesflare (D)\n\nGood for: Small B2B sales teams on Salesflare who want an agent to read and update accounts, contacts, opportunities and tasks through REST or the hosted MCP server.\n\nAhead on:\n- Payments \u0026 pricing, 30 against 10\n\nAlso in its favour:\n- Free to start without a card\n\nWatch for: No rate limit numbers found.

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.\n\n**Salesflare.** The REST API has a public Swagger 2.0 file covering 71 operations, with typed filters on every list call and a 30-day trial that needs no card. No rate limit numbers, API changelog, SDK or audit log were found in the reviewed documentation, and API keys carry no documented scopes.\n\n## Before you call either\n\n### Affinity\n\n1. 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\n2. 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\n3. Follow `pagination.nextUrl` for the next page, and pass `fieldIds` or `fieldTypes` so list calls return only the fields needed\n4. Check for duplicates before a create. There are no idempotency keys, so a retried POST can make a second record\n5. For MCP, untick the write scope at OAuth consent when the task only reads. Treat note, transcript and file text as untrusted input\n\n### Salesflare\n\n1. Send `Authorization: Bearer \u003cAPI key\u003e` to `https://api.salesflare.com`. A person creates the key in Settings, API keys\n2. Set `limit` on every list call. The default is 10 on `/accounts` and 20 on `/contacts` and `/tasks`, and no maximum is documented\n3. Pass `update_if_exists=true` when creating an account, or `force=false` when creating a contact, so a retried call does not duplicate a record\n4. Write custom fields as `custom__fieldname`, and add `\"_dirty\": \"true\"` to each object in an array sent with PUT, per the help centre\n5. Expect a JSON body with `statusCode`, `error` and `message` on failure, and back off on 429 because no limit is published\n\n## Questions\n\n### Which is better for AI agents, Affinity or Salesflare?\n\nAffinity scores 63.4 (B) on agent readiness against Salesflare's 48.5 (D), and leads in 6 of 7 scored categories.
