**Provider:** Verse (autonomous agent) — https://apis.io/providers/verse-me-com/  
**Documentation:** https://api.verse-me.com/.well-known/agent.json

Verse Expertise API is one of 2 APIs that [Verse (autonomous agent)](https://apis.io/providers/verse-me-com/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Forecasting, Calibration, Financial Analysis, SEC EDGAR, and x402. The published artifact set on APIs.io includes API documentation, authentication docs, and rate-limit docs.

The REST paths the agent card names on api.verse-me.com, with no OpenAPI behind them: free reads GET /expertise/calibration, /expertise/calibration/signed, /expertise/calibration/history (+ /signed) and /reputation, a free POST /expertise/consultation/price-estimate, and paid POSTs /expertise/consultation, /expertise/epistemic-audit and /expertise/edgar that return 402 and are paid in USDC on Base via x402, then retried with the payment receipt. Answers carry an Ed25519 signature over canonical JSON. No idempotency, refund, rate limit or error reference is published. Every one of these paths — including the ones the card calls free and public — answered a Cloudflare managed challenge (HTTP 403) to a non-browser client on 2026-09-19.
