Claude API key — Opus 5, Sonnet 5, Haiku — 70 percent below official

Product description

=== WHAT YOU GET ===

An API key with prepaid balance for Claude models, served over the

official Anthropic Messages API. Same request and response format,

same SDKs, no wrapper.

Delivered automatically within 1-2 minutes of payment.

=== REAL CLAUDE - VERIFY IT YOURSELF ===

We do not swap Claude for a cheaper third-party model, and we do not

rewrite its answers. Check it in one minute:

• The official Anthropic SDK works against our endpoint with no patch

and no compatibility layer.

• Message IDs come back in Anthropic's native format (msg_011C...).
• Every response carries the request-id header.
• Extended thinking returns real thinking blocks with valid signatures.

Still unsure? Send the same prompt to api.anthropic.com and to our

endpoint, then compare the two answers yourself.

=== PRICES ===

$10 of balance - you pay $7.50

$25 of balance - you pay $18.75

$50 of balance - you pay $37.50

$100 of balance - you pay $75.00

One order unit = one separate API key with $10 of balance.

Buy as many units as you need.
