How to Connect Upstash to an AI Agent
Auth setup
1. Create an account at https://console.upstash.com. 2. Create a database (Redis or Kafka). 3. Copy UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN from the database details page. 4. For admin ops (listing DBs), create an API key at Account > Management API.
Key facts
| Base URL | https://api.upstash.com/v2/ (management) + database-specific REST URLs (data plane) |
|---|
| API version | v2 (management) + Redis-over-HTTPS for data |
|---|
| Auth | Basic authentication for the management API (email:api_key from account settings). Data plane uses per-database REST tokens: each database has a UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN pair; the token goes in the Authorization: Bearer header. |
|---|
| Scopes | Management API keys are account-wide. Database REST tokens are scoped to one database. |
|---|
| Request body | application/json or path-encoded command |
|---|
| Pagination | Management API: typically paginated with `cursor`. Data plane: scan cursor (SCAN command). |
|---|
| Rate limit | Free tier: 10,000 commands/day per database, 1,000 requests/sec. Pay-as-you-go scales to millions. Per-second limits are enforced at the REST edge. |
|---|
| Error format | JSON: {"error":"..."} for data plane. {"error":"...","code":"..."} for management. |
|---|
Key endpoints
| Method | Path | Description |
|---|
POST | /v2/redis/database | [management] Create a new Redis database |
GET | /v2/redis/databases | [management] List all databases in the account |
POST | {REST_URL}/set/{key}/{value} | [data] Set a key (REST command syntax) |
POST | {REST_URL}/get/{key} | [data] Get a key value |
POST | {REST_URL}/pipeline | [data] Pipeline multiple Redis commands in one HTTP call |
Quickstart
POST https://{database}-12345.upstash.io/set/session:abc/user_42/EX/3600
Authorization: Bearer {REST_TOKEN}
Response: {"result":"OK"}
Agent pitfalls & tips
- Upstash's REST-over-HTTPS is designed for serverless/edge — no connection pooling needed, unlike regular Redis drivers.
- Use /pipeline to batch multiple commands — one HTTP call instead of N, dramatically reduces latency on edge functions.
- Commands with arguments are path-encoded: /set/{key}/{value}/EX/{ttl} — URL-encode values that contain special chars.
- Global databases (multi-region replication) have eventual consistency — don't use for strongly-consistent session state.
- Free tier is generous enough for hobby projects but 10k commands/day caps early. Monitor in the console.
- Upstash also offers Kafka and QStash — same REST-token model; ideal for serverless event pipelines.
