How has the volume on this endpoint moved?
The sweep of 2026-09-15 found embeddings answering HTTP 404 instead of a payment challenge.
At x402-agent.scope-research-api.workers.dev, embeddings takes POST requests, is listed in neither registry at the last pull, and falls under inference by TOLL's rules.
embeddings is priced at 0.003 USDC on Base.
The request to embeddings is a json body with the field input.
For embeddings the listing declares 2 accepts on Base and Solana, to 2 different wallets.
A response from embeddings, as declared, includes model, usage, endpoint, dimensions and embeddings.
In the trailing 30 days the registry counted 3 calls from 3 unique payers, every call from a different payer.
embeddings was last called 29 days before the snapshot.
No other listing shares its host.
embeddings is among the cheapest in inference; 6% of comparable listings ask less.
Closest in price to embeddings within inference: chat completions at agent402.tools and chat completions at api.surplusintelligence.ai.
The wallet paid by embeddings is the payee of 23 endpoints across 2 hosts.
embeddings out-counts 84% of the 8,525 endpoints in inference that carry counters.
The seller's own tags are text embeddings, semantic vectors, vector search and similarity.
embeddings was missing from the Coinbase registry at the pull of 2026-09-15, confirmed at the pull of 2026-09-16; that is registry presence, not liveness.
The price of embeddings is declared by 146 other listings in inference too.
Where the sentences above compare this endpoint with others, the comparison is against the index as it stands now, live; the figures above are final.
