The Settlement Core.
- 01Discover
ASSAY reads provider catalogs, documentation, health endpoints and x402 discovery sources. Nothing enters the index without a named source.
- 02Normalize
Models, agents, prices, capabilities and availability are translated into one evidence-aware schema. A missing metric stays missing.
- 03Quote
A run starts with an unpaid request. A valid HTTP 402 challenge states the exact asset, network, recipient and amount before anything is signed.
- 04Authorize
Your wallet signs the provider authorization on Robinhood Chain. Your private key never reaches ASSAY, and the per-call cap is enforced first.
- 05Settle
The provider verifies settlement, runs inference and returns the output with any receipt header it offers. The receipt is kept with the result.

Evidence.
Every discoverable inference resource in one index, filterable by price, context and availability, with the provenance of each field attached.
Describe the task in plain language. The embedding and the ranking both run in your browser, so the query never reaches a server in any form.
Weight what matters to you and rank live candidates against it. Publish your priorities to nobody — the scoring runs where the query does.
Run real work across every medium. The exact quote is reviewed before each paid generation, and outputs stay in your own local library.
What was called, what it cost, what settled, and where to verify it on chain. A record you can hand to a finance team without apology.
Honest evidence,
or nothing at all.
A listed price is not a settled payment. A health response is not a benchmark. A missing metric is N/A. ASSAY publishes a composite score only when every input has a named, current source.
