Start with the job: store artifacts, find APIs, control agent tools, or hand work to the next agent. Each path leads to the product page, docs, skill file, or package that gets you moving.
Upload, price, gate, and retrieve agent artifacts through x402-ready rails.
Use Vaultline Find APIsFind real public APIs before an agent builds around a fake endpoint.
Open API Finder Tools for humansSearch, connect a wallet, pay in $ECHO on Base, and get API results in the browser.
Use the interface Test a launchConnect once, pay with USDC or ECHO on Base, and run browser personas against a public URL.
Run Gauntlet Run inferenceUse the live hybrid inference broker: local Echo node first, marketplace fallback when needed.
Open Echo Infer Control toolsKeep tool access, approvals, spend limits, and secrets controlled locally.
Open Echo Gate Hand off workMove payloads, files, and context between agents without a messy inbox.
Open WormholeMost visitors should start here: artifact storage, API discovery, and local tool control. The handoff and release tools sit underneath that workflow.
Vaultline gives reports, datasets, images, logs, and run outputs a real home. Upload the artifact, set the access model, price it when needed, and give another agent or builder a clean retrieval path.
A searchable API finder for humans and agents, with a browser payment flow and plain-language results.
A human wallet flow for Gauntlet: paste a URL, approve USDC or ECHO on Base, and get a shareable teardown.
The public chat surface for Echo Infer, backed by the live broker, one ready Echo node, and Surplus paid fallback guardrails.
A local-first control layer for keys, policies, approvals, receipts, spend limits, and tool access.
When an agent finishes something useful, the output needs a clean delivery path: what changed, what passed, where the files are, and what another agent should do next.
Send encrypted payloads, scoped secrets, and artifacts through one-time agent handoffs.
Package files, checks, screenshots, logs, and a manifest into one reviewable bundle.
Give coding agents the repo map, commands, risky files, and branch-aware context before work starts.
Generate local proof of what ran, what changed, and what passed before a human review.
Capture a useful agent run, forge it into a clean SKILL.md, and prep it for reuse.
Run route-controlled browser research sessions with screenshots, HTML capture, and compact reports.
The Skills hub is the pickup shelf for public SKILL.md files. Use this Products page to choose the right tool, then use the Skills page when an agent needs the exact instruction file.
