Live x402 endpoint you can pay today: ETH regime classifier, $0.05 USDC on Base #34

Description

Hi @thisyearnofear — this is a direct ask, not a bug report.

Why you specifically: "were you wrong, or just not right long enough" is a regime question. A per-hour regime label for the window a user's loss actually happened in lets earlynotwrong ground that verdict in the tape instead of in vibes — a drawdown inside CHOP reads very differently from the same drawdown inside TREND-DOWN. You already do on-chain behavioral analysis; this is the market-state axis next to it.

What it is: GET https://dev.gavedu.com/x402/regime returns an ETH market-regime label (TREND-UP / TREND-DOWN / RANGE / CHOP) computed from EMA10/30 gap + slope + RSI over Coinbase hourly closes. Deterministic, no LLM — every field is re-derivable from public data, which is the point.

Sample response shape:

{"regime":"RANGE","price":3455.2,"rsi":51.3,"gap":0.07,"slope":0.12,"asOf":"2026-08-19T11:00:00Z"}

The ask: point your client at it once and pay the $0.05. I want the receipt more than the five cents — you'd be our first external x402 payer and I need proof a stock client completes the flow end to end against us. Happy to jump on a call or screen-share and walk it through, or debug on your side if anything doesn't parse.

Two things I owe you up front, because "verify, don't trust" is the whole pitch:

  1. Our 402 currently carries the payment requirements in the payment-required header (x402 v2) and returns an empty JSON body ({}, content-length 2). If your client reads accepts out of the response body (older x402-fetch / x402-axios), it will fail. Tell me and I'll get it fixed same day — that answer alone is worth the issue to me.
  2. No performance claim. This is an indicator output, not a signal with a track record. Do not buy it as alpha. It is the exact classifier we use to gate our own lanes, nothing more.

If $0.05 is the wrong number, name one down to $0.01 and I'll get the price changed. I'm not going to give it away free — a free call isn't the thing I'm trying to prove.

Close this if it's noise, and sorry for the interruption if so.
