  • Only Alchemy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Alchemy the free tier is capped at 30M compute units a month and 25 requests per second; Anthropic API aWS Marketplace lists Claude Opus 4.8 (Amazon Bedrock Edition), published by seller Anthropic, at $5.00 per million input tokens and $25.00 per million output tokens for standard usage, or $2.50 and $12.50 per million tokens respectively for batch processing
  • They diverge on capability: Alchemy covers Node APIs, Anthropic API covers Multiple models.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alchemy

  • The free tier is capped at 30M compute units a month and 25 requests per second
  • Free accounts are limited to 5 apps and 5 webhooks
  • Beyond the free allowance it is $0.45 per 1M compute units for the first 300M a month
  • Request cost varies by call complexity, from around 10 compute units to over 100, so spend is hard to predict from request counts alone
  • Signed SLAs and priority support require an Enterprise contract

Anthropic API

  • AWS Marketplace lists Claude Opus 4.8 (Amazon Bedrock Edition), published by seller Anthropic, at $5.00 per million input tokens and $25.00 per million output tokens for standard usage, or $2.50 and $12.50 per million tokens respectively for batch processing
  • AWS Marketplace's Anthropic listing shows cache write tokens billed separately at $6.25 per million tokens for the standard 5-minute cache, rising to $10.00 per million tokens for a 1-hour cache TTL
