## What it does

Discovery catalog only — this MCP server is free to call. Its tools \(list\_text\_tools, how\_to\_pay\) return the live SKU list with per-call prices read from our x402 manifest and exact payment instructions. The text APIs themselves are paid per call directly to the seller wallet via x402 \(HTTP 402 challenge + EIP-3009 USDC settlement on Base mainnet\): /v1/sentiment 0.001, /v1/entity-extract 0.002, /v1/summarize 0.005, plus report, batch, embeddings and similarity SKUs. No API keys, no accounts.

## How to buy

```text
PAID ($0/call). This listing's endpoint did not answer FiatDock's last check (last checked 2026-10-25T15:49:31.018Z), so it may be asleep or gone — but that check can be hours old, and free hosts wake on the first request. Trying is safe: You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid.
