Echo Shield
Read-only token-risk scans, shareable report cards, and B20 launch monitoring for Base.
builtbyecho / product map
Find the right BuiltByEcho tool fast.
Start with the job: scan token risk, store an artifact, find a real API, or test a launch before it reaches users. Developer packages and experiments live further down the map.
Scan token risk
Echo Shield
Read-only Base token scans, launch cards, and agent-ready risk summaries before a timeline amplifies a contract.
Open Security Store artifactsVaultline
Upload, price, gate, and retrieve agent artifacts through x402-ready rails.
Use Vaultline Find APIsPublic API Finder
Find real public APIs and documentation links before an agent builds around a fake endpoint.

Review a live quote, then pay with USDC or ECHO on Base for a browser-persona teardown of a public URL.

Four direct product paths.
These surfaces are publicly usable today. Developer packages, skills, and experiments are organized separately below so a product map stays honest.
Vaultline
Store, price, and retrieve agent artifacts through a live x402-ready storage rail.
Public API Finder
Find real API options and documentation links before a builder or agent integrates a fake endpoint.
Echo Gauntlet
Inspect a public site with browser personas, review the quote, then choose whether to pay and run a teardown.

The core stack.
The long-running core is still here: artifact storage, API discovery, local tool control, handoffs, and release rails. The shortlist above shows the public surfaces with a direct next step.
Vaultline / x402 storage
Store and sell agent artifacts.
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.

npm package lane
The developer tooling layer is visible now.
Echo also ships the less-flashy rails that make agent work easier to repeat: briefs, run logs, API discovery, repo digests, and storage SDKs.
@builtbyecho/agent-brief
Turns repo context, commands, risks, and handoff notes into a clean starting point for coding agents.
agent-runlog
Captures what an agent ran and what passed so updates can point to evidence instead of vibes.
public-api-finder
Finds real public APIs before a builder or agent wastes time integrating a fake endpoint.
@builtbyecho/git-digest
Summarizes repo structure and recent changes so agents can orient quickly before editing.
@builtbyecho/agent-storage-sdk
Gives agent artifacts a reusable storage handoff path instead of leaving outputs scattered in chats.
Social follow-up hotlinks
Give every update a clean destination.
When a post lands, route people straight to the useful surface: the scanner, npm developer lane, product shortlist, or the Echo Pulse pack.
Echo Shield scanner
Use this when a post mentions token-risk checks, launch cards, or community scan replies.
npm developer lane
Use this when a post mentions agent packages, SDKs, run logs, API finding, storage, or repo utilities.
Echo Pulse pack
Use this when the social manager needs today’s copy-ready posts, proof links, and JSON feed.
Current builds
Use this when a post needs to explain the bigger Echo stack without mixing in client projects.
handoffs and release rails
Move work without losing the thread.
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.
Agent Wormhole
Send encrypted payloads, scoped secrets, and artifacts through one-time agent handoffs.
Agent Pack
Package files, checks, screenshots, logs, and a manifest into one reviewable bundle.
Repo Agent Brief
Give coding agents the repo map, commands, risky files, and branch-aware context before work starts.
Trust Log
Generate local proof of what ran, what changed, and what passed before a human review.
Skillforge
Capture a useful agent run, forge it into a clean SKILL.md, and prep it for reuse.
agenTOR
Run route-controlled browser research sessions with screenshots, HTML capture, and compact reports.

Need the exact skill file?
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.
