Compatibility Check

Are two tools compatible? Verified data from 6,622 pairs and 58,638 manifest co-occurrences from real repos.

Stack Architect

Send your full proposed stack. Get a compatibility matrix, conflict warnings, and migration alternatives for every package pair. Pre-flight intelligence for coding agents.


          POST /v1/stack/architect {"packages": ["react", "nextjs", "supabase", "prisma"]}

How it works

Agent sends a request to an oracle endpoint
Server responds with HTTP 402 and a payment requirement (amount, wallet, network)
Agent signs a USDC payment on Base and resends with the payment header
Server verifies payment and returns the data

Try it

Hit an endpoint to see the 402 payment challenge:

curl -v https://indiestack.ai/v1/compatibility/nextjs/supabase

Discovery

x402-capable agents can discover these endpoints programmatically:

curl https://indiestack.ai/.well-known/x402-resources

Example response

After payment, a compatibility check returns:

{"tool_a": "nextjs",
 "tool_b": "supabase",
 "compatible": true,
 "confidence": "verified",
 "success_count": 47,
 "cooccurrence_count": 312,
 "related_tools": ["prisma", "lucia-auth"]}
