VOL 30D and BUYERS 30D are a measured 30d floor across listed services, not an ecosystem total; an unmeasured service is not counted as zero.

·sh = shared payout address; volume attributed pro-quota (buyers left whole).

QuickNode Blockchain RPC provider with x402-gated multi-chain access. Pay-per-request in USDC on Base with no API key. 3 $0.0001 100.00% $0 0 AMOY/ARCT/BSE/BSP/POL/SOL/SOLD/XLYT
Browserbase Pay-per-use headless browser sessions for AI agents. No API keys, no accounts — pay with crypto via x402 on Base. 2 $0.01 100.00% $0 0 BSE/SOL
Coprocesseur déterministe Calculs déterministes vérifiables pour agents IA : tableaux d'amortissement de prêt, distances géodésiques, conversions d'unités. Chaque réponse inclut une preuve SHA-256 vérifiable indépendamment par le client, sans avoir à faire confiance au serveur. 3 $0.001 100.00% $0.001 1 BSE
Shehriyars API Utility micro-API for web scraping, text processing, data format conversion, validation, math, crypto on-chain queries, and browser automation. 38 endpoints priced $0.001-$0.005 per call via x402 micropayments on Base mainnet. 38 $0.002 100.00% $0 0 BSE
Cloud World Model Multi-cloud infrastructure simulation API with native x402 pay-per-request support — no signup required. Lets developers, architects, and AI agents model AWS, GCP, Azure, OCI, and DigitalOcean deployments without provisioning real resources. Supports RL autoscaling training, chaos engineering, multi-cloud cost/latency comparison, predictive scaling validation, and AI-generated architecture analysis. All metered endpoints accept USDC on Base mainnet via X-PAYMENT header — no account or API key needed. 10 $0.001 100.00% $1 6 BSE/SOL
Prism Network Rent a dedicated NVIDIA GPU by the second, or call managed inference, paying per request in USDC on Base or USDG on Robinhood Chain. An agent reads the price from the 402, pays from the wallet it already has, and gets the machine to itself: any container image, SSH access, metered to the second and destroyed when the work is done. A confidential tier runs the model inside an Intel TDX enclave in front of an attested NVIDIA GPU, verified before the prompt is sent. Every lease settles onchain with a public receipt. No account, no API key. 3 $0.012144 100.00% $0.10 2 BSE
Hugen Visual API Renders any public URL to a base64 JPEG or PNG screenshot, with full-page capture, CSS selector targeting, device presets and dark mode. Returns page title, file size and render time. Paid per capture in USDC on Base or Solana. 1 $0.02 100.00% $1 ·sh 362 BSE/SOL
agent-exec agent-exec -- accountless, pay-per-use code execution for agents over x402, plus a free directory of x402 services in which every row publishes its own liveness-probe result. Every row carries the outcome and timestamp of its own last liveness probe (lastProbeCode, lastSeenAlive, dead). We re-probe every listing on a 6-hour interval; a listing that fails 3 consecutive probes is marked dead, ranks below every live listing regardless of what its owner paid, and is eventually evicted -- after 6 hours if it never once answered a probe, 30 days otherwise (a listing under a live promotion keeps its place until that promotion lapses). We do not hide failures: we publish them per row. Pass ?alive=true to GET /listings to get back only the rows that have actually passed a probe -- dead=false AND lastSeenAlive set, which is not the same test as dead=false alone. 2 $0.001 100.00% $0 0 BSE
jsonguard Repair malformed JSON and validate against a JSON Schema. POST malformed JSON (and an optional schema); returns repaired text, the parsed value, and validation errors. 0.01 USDC on Base per call via x402, no account. 1 $0.01 100.00% $0.0016666667 ·sh 1 BSE
402cron Cron for AI agents. Register an https URL and a five-field cron expression; we call it on schedule, signed with your own secret, and retry failures. You pay per delivery ATTEMPT from a prepaid balance counted in deliveries, not money — packs never expire. No account, no password, no card, no human in the loop: the only identity is the wallet that paid. Payment is x402 (EIP-3009, USDC on Base), settled through the CDP facilitator. An MCP server is available at /mcp with three tools that need no key. 4 $0.02 100.00% $7 4 BSE
