Ontario Protocol
Free agent buyer tool

Find an x402 tool for the task before paying it.

Search Ontario's fresh strict-ready provider profiles, Agentic Market, and Coinbase CDP Bazaar together by task, evidence, network, and USDC price. Providers can describe a publication task in the same box and receive the free listing preflight instead of irrelevant buyer results.

No payment occurs here. The router does not call, settle, or certify returned endpoints. Run readiness and can-pay against the exact resolved endpoint before wallet signing.

Describe the agent task

Use public task text only. Buyer-search terms are sent to Agentic Market and Coinbase CDP Bazaar. Provider-publication intent is classified locally and is not sent to those catalogs. Ontario demand analytics never retains the task text.

Candidate endpoints

Task match first. Payment never adds ranking score.
Not searched

Run a search to receive public endpoint metadata, activity boundaries, price, and a strict can-pay body.

Source counters may include tests, retries, related parties, or automation. Provider names, descriptions, prices, categories, and tags are submitted metadata. Neither is proof of unique buyers, customers, revenue, quality, endorsement, or future availability.

Agent sequence

  1. Find candidates for the exact task and hard budget.
  2. Resolve URL template variables without adding credentials to Ontario.
  3. Probe the candidate without payment and inspect its HTTP 402 metadata.
  4. Run Ontario readiness and strict can-pay for the exact resolved endpoint.
  5. Only the buyer wallet may sign; retain the payment receipt and report ID.

MCP and HTTP

The free MCP tool is find_x402_tool. The same contract is available over HTTP:

curl -sS -X POST https://ontarioprotocol.com/api/tools/x402-tool-router \
  -H 'Content-Type: application/json' \
  -d '{"query":"find recent crypto news","max_usdc":"0.01","network":"eip155:8453","limit":5}'

For endpoint providers

A paid profile becomes buyer-search eligible only while its evidence is fresh and strict-ready. Publication never adds ranking score; task relevance, network, budget, and buyer policy still decide.

Selection boundary

Ontario ranks public metadata, not private implementations. Readiness is a time-bound observation, not validation of provider claims. A result is not an endorsement, certification, settlement guarantee, or prediction of service quality. Updated 2026-08-22.
