Integrate Anthropic Claude API — Without Re-launching Your Site
LLM apps that ground answers, control cost, and pass evals
What you're seeing
You want Claude in production with tool use, streaming, vision, and prompt caching — but the SDK is new for your team.
Our approach
We integrate the Anthropic SDK end-to-end: streaming, tool use, prompt caching, retry / rate-limit handling, and per-conversation cost tracking.
Symptoms teams come to us with
- The model confidently invents facts and fake citations
- You ship LLM changes by vibes, with no eval to catch regressions
- API bills are climbing and finance wants a plan
- RAG retrieves the wrong chunks or stale documents
What we get right
- 01Retrieval grounding and citation-required prompting
- 02A scored eval harness wired into CI before changes ship
- 03Model routing, caching and batching to cut token spend
- 04Chunking, embeddings and re-ranking tuned for recall
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
Evaluation harness with scored test cases
Implementation behind feature flags + rollback plan
Cost & latency dashboard wired to your observability
Hand-off doc covering prompts, models, and guardrails
From brief to shipped fix
A transparent, low-risk process — a senior engineer reads your brief personally, and nothing starts until you approve a written plan and price.
Diagnose
A senior engineer reviews your brief, reproduces the issue, and pinpoints the real root cause — not the symptom — before any code is touched.
Scoped plan & quote
You get a written plan to integrate Anthropic Claude API, a firm timeline, and a fixed quote. Nothing starts until you approve it — no surprise invoices.
Ship the fix
We implement on a branch and open a pull request you review, working to your code-review standards on your repo — never a black box.
Verify & hand off
We verify on staging and production, share before/after evidence where it applies, and leave you a short hand-off note so the fix sticks.
Why teams hand this task to Krapton
Senior engineers only
Your brief is read and handled by a senior engineer — no junior hand-off, no sales-rep filter in between.
Root cause, not a patch
We reproduce and fix the underlying cause, then add a guard so the same class of issue does not quietly return.
Your repo, your standards
Every change lands as a pull request you review, on your repository, following your existing review process.
NDA on day one
Confidentiality and IP are covered before we look at a single line of code. All work stays in your accounts.
Fixed quote up front
You approve a written plan and price before work starts. If scope changes, we re-quote in writing — no surprise invoices.
Proof, where it applies
Performance, SEO and reliability work ships with before/after evidence so the result is measurable, not anecdotal.
