Hard caps for LLM APIs. So one provider can't kill your product.

Drop-in SDK that wraps your existing OpenAI / Anthropic / DeepSeek client. Set hard spend caps, get automatic failover when a provider 429s or bans you, and kill any customer's access in one API call.

One line. Zero proxy. No latency tax.

// Before
const client = new OpenAI();
// After — same interface, hard caps enforced
import { wrapOpenAI } from '@simplifai/budget-guard';
const client = wrapOpenAI(new OpenAI(), {
hardCap: { daily: 10_00, perCustomer: 1_00 }, // cents
fallback: ['deepseek', 'openrouter'],
});

This already happened to real teams

Three weeks in April 2026 that changed how we think about LLM provider risk.

"Anthropic disabled 60 employees' accounts in 15 hours — no warning, no SLA, contact via Google Form."

Belo / Tom's Hardware Apr 22 2026

"Claude Code removed from $20 Pro plan — reversed only after 579-upvote HN thread and public revolt."

HN 47854477 Apr 2026

"DeepSeek v4 launched at ~5× cheaper than Opus 4.6. OpenAI raised GPT-5.5 to 2× the price. Same day."

Everything your LLM stack is missing

price_check

Hard spend caps

Per API key, per customer, per model, per time window. Cap math is bit-exact deterministic — no surprises on your bill.

swap_horiz

Automatic failover

When OpenAI 429s, you hit a cap, or a provider bans your key — instantly route to DeepSeek, Anthropic, or OpenRouter.

block

Per-customer kill-switches

Cut off any customer's LLM access in one API call. Essential for fraud prevention and metered SaaS products.

route

Cost-aware routing

Route to the cheapest capable model for each call. Pricing catalog synced daily. 10× spread between providers means routing pays for itself.

speed

<50ms p99 overhead

Pre-call evaluation runs on Cloudflare Workers + Durable Objects. Strong consistency per customer with no latency tax on your requests.

analytics

LLMeter integration

Telemetry exportable to LLMeter via API key. One dashboard for observability (what you spent) and enforcement (what you're allowed to spend).
