- Crypto: +47%
- TTS: +52%

## 2) Competitive snapshot

### QR-code generation
Top players are mostly static image generators and enterprise tools. Main gap: dynamic redirect editing and privacy controls.

Observed gaps:
- Limited dynamic QR support at API-first pricing
- Weak analytics beyond basic scan counts
- Missing GDPR delete workflows for analytics records
- Logo and branded controls often locked behind expensive tiers

### Email validation
Top providers have strong datasets, but pricing and real-time latency guarantees remain pain points.

Observed gaps:
- Limited SLA-backed low-latency mailbox checks
- Daily throttles at high volume
- Incomplete unified risk scoring (disposable + spam trap + catch-all risk)

### Crypto price feeds
Strong incumbents exist, but verifiable cross-market intelligence is still fragmented.

Observed gaps:
- Incomplete signed/verifiable median across CEX + DEX
- No mainstream implied-vol API coverage
- Missing slippage estimates across execution sizes

### Text-to-speech
Quality is rising fast, but real-time latency and accessibility bundles remain under-served.

Observed gaps:
- Real-time bot latency still too high for many use cases
- On-the-fly voice cloning with robust compliance is rare
- Simultaneous subtitle generation + TTS for under-served languages is underbuilt

## 3) Audience and pain points

### Indie dev / no-code builders
Need instant keys, low friction, free tiers, quick examples.
Pain: forced card entry and unclear overages.

### MarTech / CRM SaaS
Need very high accuracy, compliance docs, predictable latency.
Pain: "unknown" verdict rates and sudden pricing jumps at scale.

### Web3 products
Need signed data, low latency, stream support, predictable trust.
Pain: REST-only integrations and limited execution-quality metadata.

### Accessibility / EdTech
Need broad language support, subtitles, mixed output formats, emotional control.
Pain: opaque per-character pricing and limited offline policies.

## 4) Product opportunities worth shipping

### QR API opportunities
1. Dynamic destination updates for printed campaigns at SMB pricing.
2. GDPR-compliant delete endpoint for analytics artifacts.
3. Crypto-pay QR payload support (including Lightning invoices).

### Email API opportunities
1. Sub-250ms SLA-backed validation endpoint for signup walls.
2. Full risk score output in one call.
3. Flexible pay-as-you-go billing options for global teams.

### Crypto API opportunities
1. Verifiable median feed from CEX and DEX in one response.
2. Slippage estimator for practical trade sizes.
3. Derivatives-oriented endpoints (volatility surfaces, confidence tags).

### TTS API opportunities
1. Sub-150ms optimized mode for voice agents.
2. Privacy-preserving cloning workflow with explicit opt-out controls.
3. TTS + subtitle dual-output endpoint for accessibility flows.
