Step 2 — Monitor Cohere API programmatically
Use the Prismix API in your CI pipeline or monitoring script:
curl
curl https://prismix.dev/api/v1/statuses | jq '.services[] | select(.id=="cohere")'
Python (with Cohere SDK guard)
import cohere
co = cohere.ClientV2(api_key="YOUR_KEY")
# Health check: list models (fast, low cost)
try:
models = co.models.list()
print(f"Cohere operational: {len(models.models)} models available")
except cohere.errors.CohereAPIError as e:
# status 503 = service degraded, 429 = rate limited
print(f"Cohere issue: {e.status_code} — {e.body}") Direct API probe
# 401 = API is up (key required), 5xx = outage curl -I -s https://api.cohere.com/v1/models | head -1
Common causes of "Cohere API not working"
If Prismix shows Cohere as "Operational" but your calls are failing:
- Wrong base URL — use api.cohere.com/v1 — the legacy domain
api.cohere.aiis deprecated but still resolves; the canonical ishttps://api.cohere.com/v1. Update to cohere-sdk >= 5.0 which uses the new domain automatically. - Command R vs Command R+ model IDs — use
command-r-plusorcommand-r(hyphenated, lowercase). Older IDs likecommandwithout a version suffix still route to older models. - Trial key hitting daily limits (429) — trial API keys have low RPM and daily token caps. Production keys require upgrading at
dashboard.cohere.com. Check theX-RateLimit-Remainingheader on every response. - Embed endpoint dimension mismatch —
embed-english-v3.0returns 1024 dimensions by default. If your vector store expects a different size, passinput_typeand setdimensionsexplicitly in the request. - Rerank scores clustering near 0 or 1 — Rerank scores are relative, not absolute probabilities. Scores that all cluster near 0.0 or 1.0 usually mean the documents are too similar to each other or the query is too generic; refine the query before diagnosing an API issue.
- EU data residency endpoint — EU-contracted customers must use
api.eu.cohere.cominstead of the global endpoint. Using the wrong endpoint violates data residency terms; verify your contract before choosing the endpoint.
