Migrate from Vercel AI Gateway
Tangle Gateway supports the same providerOptions.gateway schema as Vercel AI Gateway. Most code works unchanged.
What maps directly
| Vercel Feature | Tangle Equivalent | Notes |
|---|---|---|
providerOptions.gateway.byok | Same | Identical schema |
providerOptions.gateway.zeroDataRetention | Same | 13 verified providers |
providerOptions.gateway.disallowPromptTraining | Same | 25 verified providers |
providerOptions.gateway.caching: 'auto' | Same | Anthropic cache_control injection |
providerOptions.gateway.order | Same | Provider priority |
providerOptions.gateway.only | Same | Provider allowlist |
models fallback array | Same | Model-level failover |
GET /v1/credits | Same | Balance check |
GET /v1/generation | Same | Request detail lookup |
What’s different
| Feature | Vercel | Tangle |
|---|---|---|
| Base URL | ai-gateway.vercel.sh/v1 | router.tangle.tools/v1 |
| Auth | API key or OIDC token | API key, session, SIWE (wallet), or SpendAuth (on-chain) |
| Pricing | Zero markup | 20% markup (0% with BYOK) |
| Operator network | None | Registered Tangle operators expose endpoints, prices, and health data |
| On-chain payments | None | SpendAuth (EIP-712) - pay without a credit card |
| Guardrails | None | PII + injection detection built-in |
| Web search tools | Perplexity, Parallel, provider-native | Not available through Tangle Gateway today |
| OIDC auth | Vercel-only | Not applicable |

AI SDK
import { generateText } from 'ai'
+ import { createOpenAI } from '@ai-sdk/openai'
+ const tangle = createOpenAI({
+ apiKey: 'sk-tan-YOUR_KEY',
+ baseURL: 'https://router.tangle.tools/v1',

+ model: tangle('anthropic/claude-sonnet-4-6'),
prompt: 'Hello',
providerOptions: {
gateway: {
zeroDataRetention: true, // works the same
caching: 'auto', // works the same
},
},
})OpenAI SDK
const client = new OpenAI({
- apiKey: process.env.AI_GATEWAY_API_KEY,
- baseURL: 'https://ai-gateway.vercel.sh/v1',
+ apiKey: process.env.TANGLE_API_KEY,
+ baseURL: 'https://router.tangle.tools/v1',
})What you gain
- Operator network. Access registered Tangle operators selected by endpoint health, model support, price, latency, and reputation data.
- On-chain payments. Pay with crypto via SpendAuth - no Stripe/credit card required.
- Wallet auth. Sign in with Ethereum (SIWE) for web3-native access.
- Guardrails. Built-in PII and prompt injection detection on every request.
- Self-hostable. Deploy your own gateway instance - it’s open source.
