TackleKey
3-minute starter check
Run one tiny TackleKey API request before you compare anything else
Create a project key, use the recommended low-cost text model in the cURL example, send one tiny request against your starter balance, and confirm the result in logs before scaling traffic.
The path
| Step | What to do | Why it matters |
|---|---|---|
| 1 | Create an account and open the console. | You need a project key before sending private API traffic. |
| 2 | Create a project API key and keep it server-side. | Project keys make cost and debugging easier to isolate. |
| 3 | Use the low-cost text model shown below, or copy another current text model from live pricing. | The first call should prove configuration, not stress a volatile free quota pool. |
| 4 | Send one small request, confirm it in logs, then top up only for larger paid-model testing. | This separates integration proof from the purchase decision. |
Smallest cURL check
export TACKLEKEY_API_KEY="replace-with-project-key"

}'
After the request
Check current low-cost models
Model availability changes; use live pricing before each larger test.
Unlock larger paid tests
After the starter request works, review the live USD card options only if you need more paid traffic.
Debug errors
Use the 401, 429, invalid model, base URL, and billing checklist.
Free model IDs can be volatile or quota-limited. For a first integration proof, prefer a tiny text request against the starter balance and confirm the request log. Do not put project keys in frontend code, public repositories, screenshots, or exported Postman environments.
Ready to validate the paid path?
After the starter request succeeds, review the current USD card options. TackleKey redirects card payments to Creem; the final tax-inclusive amount is shown at Creem checkout. After payment, return to TackleKey to verify the order, credited balance, request log, and one small paid-model request.
