vercel

Call the Vercel REST API with curl + jq. The user's token is in $VERCEL_ACCESS_TOKEN; every call needs Authorization: Bearer $VERCEL_ACCESS_TOKEN. Base URL: https://api.vercel.com. If the resource is team-scoped, append ?teamId=$VERCEL_TEAM_ID (set only when the user connected a team token).

Errors come back as {"error":{"code","message"}} — show message verbatim. 403 forbidden usually means the token can't see that team/project → re-connect with the right scope.

Helper for the optional team param:

TEAM=""; [ -n "$VERCEL_TEAM_ID" ] && TEAM="?teamId=$VERCEL_TEAM_ID"
AUTH="Authorization: Bearer $VERCEL_ACCESS_TOKEN"

Projects & deployments

# Projects
curl -sS -H "$AUTH" "https://api.vercel.com/v9/projects$TEAM" \
  | jq '.projects[] | {name, framework, latestProduction: .latestDeployments[0].url}'

# Recent deployments (optionally filter by ?projectId=… or &state=ERROR)
curl -sS -H "$AUTH" "https://api.vercel.com/v6/deployments${TEAM:-?}&limit=20" \
  | jq '.deployments[] | {uid, name, url, state, readyState, created}'

Diagnose a failed build

# Deployment detail
curl -sS -H "$AUTH" "https://api.vercel.com/v13/deployments/DEPLOYMENT_ID${TEAM:+&teamId=$VERCEL_TEAM_ID}" \
  | jq '{name, url, state: .readyState, error: .errorMessage}'

# Build / runtime events (the actual logs)
curl -sS -H "$AUTH" "https://api.vercel.com/v3/deployments/DEPLOYMENT_ID/events${TEAM:+?teamId=$VERCEL_TEAM_ID}" \
  | jq -r '.[] | select(.type=="stdout" or .type=="stderr") | .payload.text'

Domains & redeploy

# Project domains
curl -sS -H "$AUTH" "https://api.vercel.com/v9/projects/PROJECT_ID/domains${TEAM:+?teamId=$VERCEL_TEAM_ID}" \
  | jq '.domains[] | {name, verified}'

To redeploy, POST to https://api.vercel.com/v13/deployments with a deploymentId (or git source) body — confirm with the user first, it ships to production.

Gotchas

• Never print env-var values. Listing project env vars returns metadata; the /v1/.../env/{id} decrypt route returns secrets — don't call it unless the user explicitly asks, and even then summarize, don't echo.
• Deployment state/readyState: QUEUED → BUILDING → READY | ERROR | CANCELED.
• created/ready are epoch ms — divide by 1000 for human time.
