Units Calculation
What is a Unit
Unit is ChainStream’s billing unit. Different APIs consume different amounts of Units - more complex APIs consume more.Data API Consumption
Unit costs are tiered by computational complexity. Simple lookups cost less; aggregation-heavy and on-chain execution endpoints cost more.- Token API
- Wallet API
- Trade API
- Pool API
- Ranking API
- DEX / DeFi API
- Blockchain / Tx API
- Webhook API
- RedPacket API
CU Pricing Tiers
WebSocket Real-time Subscription Billing
WebSocket real-time data subscriptions are billed separately, charged by data bytes:Supported Subscription Channels
- Candles
- Token Data
- Ranking Data
- Wallet Data
- Trade Data
- Pool Data
WebSocket Usage Estimation Examples
Batch APIs typically have discounts. Refer to API Reference for exact consumption. WebSocket message frequency depends on market activity; high volatility periods will increase message volume.
KYT/KYA Service Billing
Cost Estimation Examples
- Market Display App
- Trading Bot
- Exchange Risk Control
Scenario: A DeFi market website showing 50 token prices, refreshing every 10 seconds

Quota Alert Settings
You can set quota alerts to receive notifications when usage reaches thresholds:Quota Exhaustion Handling
What Happens When Quota Runs Out
When monthly quota is exhausted, API will return 403 error and cannot continue to be called. Paid plan users can manually purchase additional quota to restore service.Purchase Additional Quota
Paid plan users can purchase additional quota in Dashboard, priced according to the plan’s overage rate:Payment Methods
Supported Payment Methods
Billing Cycle
- Monthly plans: Invoice generated on the 1st for the previous month
- Annual plans: Get 2 months free (equivalent to 16.7% discount)
AI Agent Payment (x402 / MPP)
For AI agents that need programmatic access without dashboard signup, ChainStream supports two on-chain payment protocols:x402 (Base / Solana USDC)
The x402 protocol enables HTTP-native micropayments. When an API call returns 402, the agent’s wallet signs a USDC transfer and retries — no account registration required.MPP (Tempo USDC.e)
MPP uses the Tempo network for payments. Gas is paid in USDC.e directly — no ETH needed.How It Works
- Agent calls any ChainStream API
- Server returns 402 (no active subscription)
- Agent fetches available plans from
/x402/pricing - Agent purchases a plan via x402 or MPP
- Server returns an API Key — agent saves it for all future calls

FAQ
How do I choose the right plan?
How do I choose the right plan?
We recommend starting with the Free plan to evaluate actual usage, then choose based on monthly consumption:
- < 30K Units: Free
- 30K - 10M Units: Starter
- 10M - 50M Units: Pro
- > 50M Units: Enterprise
Can I upgrade/downgrade anytime?
Can I upgrade/downgrade anytime?
Yes. Upgrades take effect immediately with prorated charges. Downgrades take effect in the next billing cycle.
