Claude API API Pricing, Free Access and Cost Examples (2026)

The APIMART live pricing payload currently lists Claude Haiku 4.5 at $0.80 per million input tokens and $4 per million output tokens, and Claude Sonnet 4.5 at $2.40 input and $12 output. These are effective APIMART rates observed for the exact dated model IDs below, not a single family-wide Claude price. Prices and promotions were observed on September 2, 2026; the live pricing surface and account ledger remain authoritative.

Published cost table

| Option | Observed price | Example A | Example B | Example C | |---|---:|---:|---:|---| | claude-haiku-4-5-20251001 | $0.80/M input | $4.00/M output | $0.0012 for 1K in + 100 out | $0.012 for 10K in + 1K out | | claude-sonnet-4-5-20250929 | $2.40/M input | $12.00/M output | $0.0036 for 1K in + 100 out | $0.036 for 10K in + 1K out |

These examples are arithmetic planning estimates. Actual billing depends on the exact model ID, options and completed output recorded by APIMART.

Budgeting workflow

Record the full model ID, cap output quantity or duration, submit through POST /api/v1/chat/completions, store the returned task ID, and reconcile the completed job against the account ledger. Do not treat account signup or a temporary promotion as proof of unlimited free generation.
