No official MCP server, OpenAPI spec or llms.txt.\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### Copper API\n\n1. Send `X-PW-AccessToken`, `X-PW-Application: developer_api` and `X-PW-UserEmail` on every call, or it fails\n2. Set `page_size` to 200 and stop when a page comes back short, since `X-PW-TOTAL` is only an upper bound\n3. Back off on 429 on your own clock, since no Retry-After is documented\n4. Narrow searches that would pass 100,000 records, which is where results stop\n5. Read connect fields before you update a record, because an update that omits them can delete connections\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, Copper API or Salesflare?\n\nSalesflare scores 48.5 (D) on agent readiness against Copper API's 46.7 (D), and leads in 4 of 7 scored categories.
