x402 repeat demand API: endpoints whose payers come back

Updated 2026-10-16

Which x402 endpoints get paid again

Which x402 endpoints do the same payers come back to? POST https://tanod.dev/v1/x402/repeat-demand lists endpoints from the latest daily CDP Bazaar snapshot whose payers over 30 days average 2 or more calls each, most payers first. It is for sellers and builders looking for where repeat paying demand exists. GET https://tanod.dev/v1/x402/repeat-demand?min_payers=3 also works. 
curl -s -X POST https://tanod.dev/v1/x402/repeat-demand \
  -H "Content-Type: application/json" -H "X-Tanod-Free: 1" \
  -d '{"min_payers": 3, "limit": 2}'

All fields are optional: category (for example documents or onchain-read; the categories are those of /v1/x402/pulse), min_payers (default 3) and limit (1 to 100, default 25).

Limits

Routes of hosts that the payer-pattern check flags (sweep, once per route) and of listing-farm hosts are left out. Tanod does not rate its own routes. Payers and calls are the Bazaar's 30-day figures and can include a seller's own and test wallets, so a listed endpoint is a lead, not proof of demand. Categories are keyword matches. An unknown category is a 422 and a missing or busy snapshot store is a 503; neither is charged. Names and URLs are third-party data. The list is built once per daily snapshot; the first call after a new snapshot can take up to about 30 s.

Price and free allowance

Each call costs USD 0.003 in USDC through x402. The live 402 says: "Free tier (opt-in): 10 agent-index queries per IP per UTC day with header X-Tanod-Free: 1 (no payment needed)."

It is also the MCP tool get_x402_repeat_demand. In claude.ai or Claude Desktop, add https://tanod.dev/mcp/agents?via=x402-repeat-demand-api as a custom connector (steps), then ask, for example, "Which x402 endpoints in the documents category have repeat payers?" Over MCP the free allowance is applied automatically.
