Contact Gauge

An API for AI agents. Should you talk with this person? It scores the audience cross-pollination value of a podcast swap, co-post, intro call or DM, and returns a verdict and a draft reply.

What it checks

Audience fit (next door to yours scores highest), whether their audience includes people you need, engagement, reach, value each side gets, whether they will share you, credibility, introductions, time cost and disclosure risk. Then pass/fail gates: red flags, export-controlled topics, mixing separate brands, and too many unknowns.

How an agent uses it

1. Read the fields and the paid URL: GET /v1/schema (free).
2. Check its JSON body: POST /v1/validate (free).
3. POST the body to the paid URL. It answers 402; the agent pays over x402 and gets the evaluation plus an on-chain receipt.

npm i @bsvkey/x402-bsv-client @bsv/sdk

import { fetchWithX402 } from '@bsvkey/x402-bsv-client';
const { paidEndpoint } = await (await fetch('https://gauge.bsvkey.com/v1/schema')).json();
const res = await fetchWithX402(paidEndpoint, {
  method: 'POST',
  headers: { 'content-type': 'application/json' },
  body: JSON.stringify({ name: 'Jane Smith', overlap: 'adjacent', engagement: 'real', give: 'high' }),
}, { wif: process.env.BSV_WIF });
console.log(await res.json());

Full field list for agents: llms.txt and openapi.json. Payments go straight to the operator's own BSV address through BSVKey Paywall Cloud.

This sends a sample body to the free validator and shows the fields. No payment, nothing stored.
