What is a Compute Unit (CU)? A CU measures computational resources consumed by an API request. Simple calls like eth_blockNumber cost ~10 CUs, while complex trace methods cost 1,000-50,000 CUs.

What are Compute Units (CUs)?

A Compute Unit (CU) measures the computational resources (CPU, RAM, disk I/O, network) consumed by an API request. This provides fair pricing where simple calls cost less than complex operations.

CU Costs by Method Type

Standard Methods (Low CU)

Method	CU Cost	Description
eth_blockNumber	10	Latest block number
eth_gasPrice	10	Current gas price
eth_chainId	5	Chain identifier
net_version	5	Network version

Common Methods (Medium CU)

Method	CU Cost	Description
eth_getBalance	15	Account balance
eth_call	26	Contract read call
eth_estimateGas	87	Gas estimation
eth_getBlockByNumber	21-36	Block data
eth_getLogs	75-500	Event logs (scales with range)

Trace Methods (Very High CU)

Method	CU Cost	Description
trace_transaction	1,000	Single transaction trace
trace_block	2,500	Full block trace
debug_traceCall	3,000	Simulate and trace call
debug_traceTransaction	5,000	Detailed debug trace
debug_traceBlockByNumber	50,000	Full block debug (50x multiplier!)

WebSocket Subscriptions

Type	CU Cost	Description
newHeads	40/event	New block headers
logs	40/event	Event logs subscription
newPendingTransactions	40/event	Pending tx hashes

Average Request: ~25 CUs across typical usage patterns

Why CU-Based Pricing?

Traditional "requests per minute" pricing treats all API calls equally, even though:

• eth_blockNumber takes milliseconds and minimal compute
• debug_traceBlockByNumber can take 30+ seconds and consume 5000x more resources

CU-based pricing ensures:

• Fair costs - Pay for actual compute used
• Predictable billing - Understand costs before you call
• No surprise bills - Separate trace CU pools prevent accidents
• Industry standard - Matches Alchemy, QuickNode, Infura

Competitor Comparison

Provider	Free Tier	Entry Paid	Entry CUs	CU Value/$	Chains	Trace Methods	Annual Discount
Axol	400M CUs	$39	2B CUs	51.3M/$	17	Separate pool	20%
Alchemy	300M CUs	PAYG only	300M (free tier)	7.7M/$	~30	Mixed (expensive)	None

Note: CU values are approximate conversions based on publicly available pricing (as of 2025). Actual costs may vary based on method mix. Axol provides 5-10x better value per dollar compared to competitors.

Trace Method Pricing

Why Separate Pools?

Trace and debug methods can consume 50-5000x more resources than standard calls. Without separation, one accidental debug_traceBlockByNumber could cost more than 100 regular users' monthly usage.

How It Works

1. Standard CU Pool: Covers all eth_, net_, web3_* methods
2. Trace CU Pool: Separate allocation for trace_* and debug_* methods
3. Soft Limits: Warn at 80% usage, throttle at 100%
4. Grace Period: 10% overage before hard cutoff

Trace Pool Examples

Growth Tier (100M trace CUs):

• 100,000 trace_transaction calls
• 40,000 trace_block calls
• 20 debug_traceTransaction calls
• 2,000 debug_traceBlockByNumber calls (mix is typical)

Scale Tier (1B trace CUs):

• 10x all of the above

Overage Handling

When you exceed your monthly CU pool:

1. 80% usage: Email alert + dashboard warning
2. 90% usage: Email alert + in-app notification
3. 100% usage: Soft throttle (2-second queue delay)
4. 110% usage: Hard limit OR overage billing (your choice in settings)

Overage Rates:

• Standard methods: $0.42 per 1M CUs
• Trace methods: $2.10 per 1M CUs (5x multiplier)

Annual Billing

Save 20% with annual billing:

• Growth: $31.20/month (billed $374.40 annually)
• Scale: $159/month (billed $1,908 annually)

Benefits:

• 20% discount across all tiers
• Lock in pricing for 12 months
• Priority billing support
• Cancel anytime with prorated refund

Standard CUs/month:30.5M CUs

Trace CUs/month:0 CUs

Total CUs/month:30.5M CUs

Recommended Tier: Starter

$0/month

Standard: 400.0M CUs/month

Formula: Total CUs = (Simple calls × 10) + (Standard calls × 25) + (Complex calls × 100)

Example: If you make:

• 1M eth_blockNumber calls = 10M CUs
• 500K eth_call calls = 13M CUs
• 100K eth_getLogs calls = 7.5M CUs
• Total: 30.5M CUs/month = Fits in Starter tier

Can I upgrade or downgrade mid-month?

Yes, instantly. Billing is prorated. Unused CUs do not carry over to next month.

What happens if I exceed trace CU limits?

You'll receive alerts at 80%/90%/100%. At 100%, trace methods are throttled (2-sec delay) or switch to overage billing at $2.10/1M CUs.

Why do trace methods cost 5x more?

Trace methods like debug_traceTransaction can consume 30+ seconds of compute time and gigabytes of memory, compared to milliseconds for standard calls. The 5x multiplier reflects actual infrastructure costs.

Do WebSocket subscriptions count as CUs?

Yes. Each event received (newHeads, logs, etc.) costs 40 CUs. Subscriptions count toward your standard CU pool.

Can I pay with crypto?

Enterprise tier supports USDC and ETH payments. Contact sales@axol.io.

Migrating from Old Pricing

Your account will be automatically upgraded:

Old Plan	Old Limit	New Plan	New Limit	Value Increase
Free	10K calls/mo	Starter	400M CUs (~16M calls)	1600x more

Enterprise ($99)	1M calls/mo	Scale	12B CUs (~480M calls)	480x more

Estimating Your Usage

To estimate your current usage in CU terms:

1. Simple calls (eth_blockNumber, eth_gasPrice): Count × 10 CUs
2. Standard calls (eth_call, eth_getBalance): Count × 26 CUs
3. Log queries (eth_getLogs): Count × 75 CUs
4. Trace calls (trace_transaction): Count × 1,000 CUs

Example: If you currently use 50K calls/month:

• 20K simple calls = 200K CUs
• 25K standard calls = 650K CUs
• 5K log queries = 375K CUs
• Total: 1.225M CUs = Easily fits in Starter (free)
