The legacy/core origin remains online for backward compatibility, but directories and AI agents should index https://gfpick-agent-api.vercel.app as the canonical agent-native origin.

Please re-evaluate/re-crawl this canonical endpoint for inclusion.

GF Agent Toll production update: v0.8.0 is now live with three premium x402 resources in addition to the original entry services.

Premium resources: POST /v1/gcc/product-decision (2.50 USDC), POST /v1/gcc/portfolio-rank (5.00 USDC), and POST /v1/gcc/merchant-pack (12.00 USDC). Updated machine discovery is available at /pricing, /openapi.json, /.well-known/x402, /skill.md, and /.well-known/agent-card.json on https://api.gfpick.com.

GF Agent Toll update — production v0.9.0 is now live.

New zero-friction acquisition funnel:

• Human calculator: https://api.gfpick.com/free
• Free API: POST https://api.gfpick.com/free/gcc-profit-check — 0 USDC, no wallet required
• The free result returns a preliminary profit/margin estimate, then upgrades buyers into the paid x402 ladder: 0.75 / 2.50 / 5.00 / 12.00 USDC.

Current machine-readable endpoints:

• https://api.gfpick.com/.well-known/x402
• https://api.gfpick.com/openapi.json
• https://api.gfpick.com/pricing
• https://api.gfpick.com/self-test
• https://api.gfpick.com/skill.md

Paid settlement remains x402 v2 exact on Base mainnet with canonical USDC.

Health-checked and queued — and re-crawled against the canonical agent-native origin you asked for.

Measured 2026-08-31:

POST https://gfpick-agent-api.vercel.app/v1/sa/landed-cost
  HTTP 402 in 194ms
  x402Version 2 · scheme exact · network eip155:8453
  payTo  0x4B7098E3b882633d3205FDE3E7ac7Ea1D965D3C3  (matches your submission)

  amount 250000 atomic = $0.25

PASS — live 402, payTo matches, and /.well-known/x402 confirms the same payee and canonical origin. Queued in directory/queue.json with the evidence attached; the queue probes the $0.25 landed-cost route as the cheapest paid one.

One note, not blocking: the paid routes validate the request body before the payment gate. An empty body gets 400 invalid_request, and so does a body with plausible-but-wrong keys — {"product_value":100,"category":"electronics",...} came back unrecognized_keys. Only the exact OpenAPI example shape reaches the 402. An agent that discovers you and probes with a minimal body sees a schema error instead of your price, which costs you exactly the autonomous traffic the canonical origin is meant to attract. Returning 402 before validating would fix that.

The discovery surface here is the most complete of anything submitted so far — x402 manifest, catalog, bazaar, OpenAPI, MCP, A2A card, JWKS, skill.md and llms.txt all resolve. That's noted for the review.

To be clear on status: a health check confirms the endpoint is alive and self-consistent. It is not the Verified badge, which requires a paid first-party test of the decision output. You're in the queue for that.

Closing as processed; the queue entry is the durable record.
