Price any x402 (HTTP 402 Payment Required) API across payment rails and see what the same call costs on each — live, from the server's own quote. Gas rails floor micro-prices at ~$0.001; the feeless Nano (XNO) rail quotes the true metered amount, so sub-millicent calls cost sub-millicents. **Tools:** `x402_quote` · `x402_compare` · `faucet_info` · `get_started` This hosted endpoint is read-only and holds no wallet — nothing to steal, nothing to spend. For the full self-custodied experience (pay per call, earn as a merchant, claim free starter XNO from the faucet): pip install feeless402 claude mcp add feeless402 -- uvx feeless402 mcp Docs: [feeless402.com](https://feeless402.com) · Spec: [railhint.com](https://railhint.com) · Official MCP registry: `com.feeless402/nano-pay`

MCP readiness

B · 83/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 70.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (2120 ms).
Protocol revision	8/10	Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	30/30 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 4 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	0/5	not seen in a source for over 30 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (2120 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 60% of peers; This listing 83 · peer median 81
Latency: Faster than 9% of peers; This listing 961 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags −5 — Keep the listing current in the registry or source it comes from.
Now: not seen in a source for over 30 days.
Auth declaration −3 — State how to authenticate (an auth scheme, or that none is needed).
Now: Declares credential scheme: smithery_api_key.
