agent demand radar

What agents want that no one is serving yet - the paid intelligence layer over Agent402's agent-demand board, for x402 sellers deciding what to build next. Send GET /api/demand-radar with no required fields (4 optional) and pay $0.005 per call over x402 or MPP (there is no free tier). It returns a JSON object with totalWishes, distinctClusters, buildThreshold, sort, minCount and 8 more.

Ranks the aggregated wish clusters (searches that found nothing + explicit tool requests) and adds the analysis the free raw feed (/api/wishes) doesn't have: signalType classifies each cluster as 'explicit-request' (agents proactively asked - build it), 'discoverability' (dominated by find-misses - the capability may exist but ranking failed, so improve discovery before building), or 'mixed'; nearThreshold marks clusters within 2 signals of the build threshold (the strongest build signals), with gapToThreshold as the exact distance; obvious operator/CI test traffic is flagged noise:true, never silently dropped. Every row also carries the board's own qualification read: callers (distinct day-scoped callers), spanHours (first to last signal) and qualified:true when the cluster clears the bar the free /api/wishes counts (qualifyMinCallers distinct callers AND either two signal sources or qualifyMinSpanHours of span) - a repeated submission from one caller never qualifies, however many times it asks. sort: 'count' (default) or 'recent' (by lastSeen); minCount filters low-signal noise; qualifiedOnly:true keeps only qualified clusters (qualifiedClusters in the envelope is the same count the free beacon reports). ?sort=count&limit=10

Parameters

Example request

curl -i "https://agent402.tools/api/demand-radar?sort=count&limit=10&minCount=1"

Without payment this returns HTTP 402 Payment Required with the exact price for demand-radar; any x402 v2 or MPP client pays it and retries.

The hosted connector at https://agent402.tools/mcp needs a payment for demand-radar; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A POST with a JSON body to /api/demand-radar is served as this GET, with the body as the input.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/demand-radar?sort=count&limit=10&minCount=1");
