Last updated: March 2026. By accessing any x402dash API endpoint or website, you agree to these terms.
x402dash (also referred to as x402market) is a public intelligence platform that tracks, scores, and indexes x402-compatible API endpoints. It provides liveness monitoring, metadata enrichment, and full-text search over the x402 ecosystem.
The service is open to developers, agents, researchers, and businesses building on the x402 protocol. Use is permitted for exploration, integration, tooling, and product development.
Free endpoints require no registration. Paid endpoints require a micropayment via the x402 protocol (USDC on Base mainnet). No personal account or identity verification is required.
Rate limits apply per IP address. Exceeding them returns HTTP 429 Too Many Requests with a Retry-After header. Sustained violations trigger automatic suspension.
/v1/endpoints, /v1/liveness, /v1/ecosystem,
/v1/categories, /v1/providers, /v1/runs,
/v1/health, /.well-known/x402
10 requests / minute per IP address.
Sufficient for dashboard browsing and integration testing. Not intended for automated production workloads.
/v1/search ($0.002/query), /v1/history ($0.003/query)
60 requests / minute per IP address.
Paid traffic receives full throughput. Payment is enforced independently of rate limits.
IP addresses that generate more than 500 requests in 10 minutes or more than 2000 requests per hour may be automatically suspended without prior notice.
Our infrastructure monitors traffic patterns in real time. IP addresses exhibiting abusive behavior — including rate limit violations, payment fraud attempts, or traffic patterns consistent with enumeration attacks — are automatically blocked at the network layer.
Automatic blocks may be temporary (minutes to hours) or permanent, depending on severity.
We reserve the right to block any IP address, CIDR range, or autonomous system (ASN) that violates these terms, at our sole discretion, with or without prior notice.
If you believe your IP was blocked in error, contact us at the contact page with your IP address and a description of the usage. Legitimate use cases can be whitelisted upon review.
x402 payments are settled on-chain and are final by protocol design. If access is terminated due to policy violation, no refunds of prior payments are issued.
All endpoint data is sourced from publicly accessible registries (primarily the CDP Bazaar) and from active liveness probing of publicly listed HTTP endpoints. No private or authenticated APIs are queried.
Liveness scores, metadata, and AI-enriched descriptions are provided for informational purposes. They reflect observed behavior at the time of the last check and may not represent current reality. Use of this data for financial or production-critical decisions is at your own risk.
Category labels, descriptions, and tags marked as AI-enriched are generated by a language model based on observed endpoint metadata. They may contain errors or omissions. We make no warranty of accuracy for AI-generated fields.
The service is provided "as is" and "as available" without warranties of any kind, express or implied. We do not guarantee uptime, data accuracy, or continuity of service. We are not liable for any direct, indirect, or consequential damages arising from use of or inability to use the service.
x402market is an independent monitoring tool and is not affiliated with, endorsed by, or partnered with Coinbase, CDP, or any entity operating the endpoints indexed by this service.
We may update these terms at any time. The "last updated" date at the top of this page will reflect the most recent version. Continued use of the service after a policy change constitutes acceptance of the updated terms.
