Same features for everyone.
Tiers only raise your limits.
Every tier runs the full engine - same recall quality, same languages, every method. Tiers advance automatically through Tier 5 as your cumulative credit purchases grow, with no application or sales call. Enterprise (Tier 6) is the one exception.
Spend limits
Each tier caps how much you can spend per calendar month. You advance immediately when your cumulative credit purchases reach the next threshold.
| Usage tier | Credit purchase | Monthly spend limit |
|---|---|---|
| Tier 1 | $5 | $100 |
| Tier 2 | $40 | $500 |
| Tier 3 | $200 | $1,000 |
| Tier 4 | $400 | $5,000 |
| Tier 5 | $1,000 | $25,000 |
| Tier 6 - Enterprise | Talk to us | No limit |
Rate limits
Rate limits are per account - every API key on an account shares one limit, which scales with your tier. Exceeding it returns a 429 with a retry-after header; back off (1s → 2s → 4s) and retry. Every endpoint is idempotent-friendly, so retries are safe.
| Tier | Requests per minute |
|---|---|
| Tier 1 | 150 |
| Tier 2 | 300 |
| Tier 3 | 600 |
| Tier 4 | 1,500 |
| Tier 5 | 3,000 |
| Tier 6 - Enterprise | Custom |
Enterprise (Tier 6) gets custom rate limits, an SLA, and dedicated support - talk to us.
Free calls
A few endpoints carry no charge at all - they are gathered under Won. In place of a price they have two limits.
- 10 requests per minute, per endpoint. Each free endpoint keeps its own bucket, so spending one does not spend another.
- 300 requests per hour, shared. All the free endpoints draw on one hourly allowance per account.
Neither is reachable in ordinary use, and neither touches the paid limits above.
