Authentication
Send an API key as a bearer token. The key must carry the billing.manage permission; a key without it is refused with 403, not 404.
Where your organisation id goes
This endpoint takes org_id as a field in the JSON body.
Your organisation id is on the API keys screen in your dashboard, beside the key itself. It is the same id in every call you make.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X POST https://api.zinndigital.com/v1/ai/credentials \
-H "Authorization: Bearer zdk_live_…" \
-H "Content-Type: application/json" \
-d '{ "provider": <AiProviderCode>, "api_key": <string> }'Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
Puts the key in Vault and records a pointer. Any existing live key for the same provider is revoked in the same transaction — one live key per provider, because two is not a richer model, it is an ambiguity about which key we are about to spend the customer's money through. ⚖️ **The key is TESTED before this responds** — owner instruction 2026-08-20: *"we need to test the api keys when they add them."* A **real** completion with our own prompts and tool format, not the free authentication probe: the narrower question is one a screen would render as a green tick while a recipe fails on its first run. The response carries `state`, `last_error` and `tested_on_save`. ⛔⛔ **A FAILED TEST DOES NOT FAIL THE SAVE.** The key is already in Vault by then. Refusing would leave a customer who pasted a valid key with an empty screen and no way to tell "we could not reach the provider" from "you typed it wrong", while the secret sat stored. They get it saved, the state set honestly, and the provider's own reason to act on. A `422` still means nothing was stored anywhere. ⭐ The provider's model catalogue is also filled from this key in the same call — a free authenticated read that costs the customer nothing, and the only opportunity we get for a vendor we hold no platform key for. ⛔ Vault is written **before** the row, and the row is created only if that succeeded. A `422` means nothing was stored anywhere: an unreachable secret store is a refusal, never a silent skip that leaves the customer believing their key was saved. Requires `billing.manage`.
Request body
| Name | Type | Required | What it is |
|---|---|---|---|
provider | AiProviderCode | Yes | An LLM vendor a customer may bring their own key for. `xai` was added by W24-G on the owner's 2026-08-20 instruction naming Grok alongside Claude and ChatGPT. |
api_key | string | Yes | The key itself. Written straight to Vault and never returned. |
label | string | No | — |
org_id | Uuid | No | UUIDv7 identifier — sortable by creation time (docs/02 §8). |
Response
| Name | Type | Required | What it is |
|---|---|---|---|
id | Uuid | Yes | UUIDv7 identifier — sortable by creation time (docs/02 §8). |
provider | AiProviderCode | Yes | An LLM vendor a customer may bring their own key for. `xai` was added by W24-G on the owner's 2026-08-20 instruction naming Grok alongside Claude and ChatGPT. |
label | string | Yes | — |
state | string<untested, working, broken> | No | Whether the key is known to work. ⛔ Three values, not two: "we have never tried it" and "we tried it and it failed" must not collapse, because telling a customer their valid key… |
last_checked_at | object | No | When we last *asked*, whatever the answer — distinct from `verified_at`, which is when it last *worked*. A key checked five minutes ago and broken has a recent `last_checked_at`… |
broken_since | object | No | — |
tested_on_save | boolean | No | Only on the response to `addAiCredential`. Whether the on-save test actually **ran** — ⛔ not whether it passed. `false` means we could not even try, which is `untested` and not… |
last_error | string | No | The provider's own reason, trimmed, for the customer to act on. "Your credit balance is too low" needs a different response from "this key was revoked". |
failure | VendorFailure | null | No | What the customer is told about the last failure, and where they may be sent (CLAUDE.md §57). `null` when the key works or has never been tried — ⛔ which is not the same as "fin… |
verified_at | object | No | The last time a real call on this key succeeded. ⛔ `null` means **never proven**, not broken — telling a customer their valid key is invalid is worse than saying nothing. |

created_at | string | Yes | — |
