What it does

This endpoint from EV+ AI claims to provide bias-optimized arbitrage positions, where the bias parameter ranges from 0.1 (bearish) to 0.5 (neutral) to 0.9 (bullish). It is listed as an x402-protocol endpoint, meaning callers would normally receive a 402 Payment Required challenge with on-chain payment details before accessing the data.

However, at the time of probing, the entire api.evplus.ai domain is experiencing a Cloudflare DNS misconfiguration (Error 1000), returning 403 responses on all paths including the root, /docs, /api, and the endpoint itself. No 402 challenge was captured, no OpenAPI schema is available, and no documentation could be retrieved. The endpoint is effectively unreachable.

Because no live response, schema, pricing information, or documentation could be obtained, nearly all details about this endpoint are inferred solely from its URL path and the existing catalog title. The bias parameter presumably controls the risk posture of returned arbitrage signals, but the exact request format, response structure, supported assets, and payment terms are unknown.

Quality

0.10/ 1.00

The entire api.evplus.ai domain is down due to a Cloudflare DNS misconfiguration (Error 1000). No 402 challenge was captured, no schema or docs are available, and all information is inferred from the URL path and catalog title alone.

Warnings

  • Endpoint is currently unreachable — Cloudflare Error 1000 (DNS resolution conflict) on all paths

  • No OpenAPI schema, documentation, or pricing information available
  • Domain-wide outage suggests the service may be abandoned or misconfigured
