  • Each has a real cost: Alchemy the free tier is capped at 30M compute units a month and 25 requests per second; Anthropic API pricing varies significantly by model tier
  • They diverge on capability: Alchemy covers Node APIs, Anthropic API covers Multiple models.
  • Prices and features above were last checked on 30 August 2026.

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

  • Pricing varies significantly by model tier
  • Batch processing and Fast Mode add additional surcharges
  • US-only inference costs 1.1x standard pricing
