x402 readiness

B · 81/100

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 B+, 67.6/100), which weighs availability, payability and on-chain demand. How the two differ

Valid payment requirements 10/10 Payment requirements carry a payee, a mainnet network and a price.
Live 402 challenge 20/25 Endpoint reachable; its 402 challenge was seen earlier (324 ms).
x402 version n/a x402 version not observed yet.
Signed descriptor n/a No x402 standard defines a signed descriptor.
Uptime (30 days) 15/15 32/32 probes succeeded over 30 days (100%).
Resource declaration 10/10 Declares 19 paid resource(s).
Verified identity 5/10 Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control.
Freshness + modern flags 1/5 not seen in a source for over 30 days; declares x402.
Security declaration n/a Payment is the access control for an x402 resource.
Applicable criteria total 75 points, scaled to 100.
Responsiveness: Responsive (324 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).
Payment evidence: x402_challenge — We sent a request and got a live HTTP 402 challenge. Also: x402_manifest, bazaar_feed, catalog_listing. Qualifies the payment claim; adds no points.
Measured 2026-11-11.
Nine criteria, the same as the A2A readiness score, read from our daily probe of the paid endpoint, its payment requirements and 30-day probe history. Signed descriptor and security declaration are n/a for x402 (payment is the access control), as is an x402 version we have not observed; the remaining points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. It also feeds 15 points of the x402 quality grade.

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

  • Live 402 challenge −5 — Answer the paid path with a valid 402 challenge.
    Now: Endpoint reachable; its 402 challenge was seen earlier (324 ms).
  • Verified identity −5 — Claim the listing and prove control of its domain.
    Now: Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control.
  • Freshness + modern flags −4 — Keep the listing current in the registry or source it comes from.
    Now: not seen in a source for over 30 days; declares x402.

How many agent tools actually work · All statistics

Paid endpoints

19 resource(s) advertised by this origin. Each price below is that resource's own x402 price; the headline price is the range across them.

GET https://sharvora.com/api/v1/service-proof

Use as a low-cost end-to-end x402 canary before higher-value calls. A successful paid response proves Sharvora delivery and returns release, network, time and a response receipt.

POST https://sharvora.com/api/v1/quant/risk-state

Use when an agent has an ordered numeric series and needs quantitative risk context before making a downstream decision.

POST https://sharvora.com/api/v1/quant/anomaly

Use to rank unusual observations in a supplied numeric series with structured anomaly evidence.

POST https://sharvora.com/api/v1/quant/forecast-range

Use for a bounded probabilistic range estimate from a supplied time series when an agent needs bounded uncertainty, not a trade instruction.

POST https://sharvora.com/api/v1/quant/flow-monitor

Use to normalize supplied exchange, bridge and stablecoin inflow/outflow values into net-flow direction and intensity context.

POST https://sharvora.com/api/v1/decision/preflight

Use immediately before an automated decision to check observation age, missing context and optional series risk for explicit warning conditions.

POST https://sharvora.com/api/v1/decision/journal

Use to create a durable auditable decision record with a stable decision_id, context hash, horizon, direction and confidence for later evaluation.

POST https://sharvora.com/api/v1/decision/bundle

Use when an agent wants one payment and one response for freshness, completeness, risk, anomaly and forecast evidence over the same supplied series.

POST https://sharvora.com/api/v1/decision/audit

Use after an outcome is known to compare it with a prior Sharvora decision record and calculate change and directional hit evidence.

POST https://sharvora.com/api/v1/web/trust-passport

Use when an agent wants one integrated trust purchase: combines multiple public trust and readiness signals into a structured evidence passport.

POST https://sharvora.com/api/v1/web/agent-readiness

Use to audit whether a public website exposes machine-readable agent surfaces such as robots, sitemap, llms.txt/llms-full, OpenAPI, RFC 9727 API catalog, A2A discovery, x402 and security.txt.

POST https://sharvora.com/api/v1/web/redirect-audit

Use to inspect a public URL redirect chain, cross-origin hops, loops and HTTPS-to-HTTP downgrade evidence with private-network redirect protection.

POST https://sharvora.com/api/v1/web/endpoint-trust

Use before an agent trusts a public endpoint: combines bounded public endpoint trust evidence into a structured risk assessment.

POST https://sharvora.com/api/v1/web/http-policy

Use to inspect a public HTTP response's cache, CORS, cookie and browser-policy posture as a point-in-time evidence snapshot.

POST https://sharvora.com/api/v1/web/security-headers

Use for a no-login audit of a public HTTP(S) page's major browser security headers and a prioritized list of missing protections.

POST https://sharvora.com/api/v1/web/tls-report

Use to check a public hostname's TLS certificate issuer, SAN coverage, cipher and expiry window without requiring credentials to the target site.

POST https://sharvora.com/api/v1/x402/validate

Use to inspect a public x402 URL without spending funds: confirms HTTP 402 behavior and decodes v2 payment metadata when available.

POST https://sharvora.com/api/v1/evidence/receipt

Use when an agent needs a deterministic SHA-256 content-integrity receipt for exact UTF-8 text. This is off-chain and does not claim notarization.

POST https://sharvora.com/api/v1/evidence/consensus

Use to measure agreement, freshness and contradictions across caller-supplied numeric observations with transparent confidence and weighting evidence.
