# Research a third-party API before integrating it in Echo with Atlas in 2026 > Echo developers use Atlas to research third-party APIs, ensuring integrations align with `echo.NewHTTPError` and are verified by `go test (httptest)`. Echo developers in 2026 can leverage Atlas to efficiently get the current shape of an external API into context before writing an integration, eliminating guesswork. Atlas uses `websearch` and `webfetch` to retrieve up-to-date documentation, then assists in drafting the integration, ensuring it aligns with Echo's typed `Context`, custom binders, and `HTTPErrorHandler`, all while respecting your existing `go mod` dependencies and verifying with `go test (httptest)`. ## Key takeaways - Atlas uses `websearch` and `webfetch` to get current API documentation for Echo. - Integrate third-party APIs into Echo with Atlas, adhering to `echo.NewHTTPError` patterns. - Atlas drafts `go test (httptest)` coverage for new Echo handlers. - Verify Echo code conventions with `grep` and format with `gofumpt` before committing. - Every Atlas tool call for Echo integration is permission-gated for security. ## How to find current API documentation for Echo integrations with Atlas Finding the most current API documentation is the crucial first step for any Echo integration in 2026. Atlas uses its `websearch` tool, which automatically injects the current year into its queries, to bias results towards fresh sources, ensuring you're not working with outdated specifications. When an Echo application needs to interact with a new external service, understanding its API contract is paramount. Instead of manually browsing or guessing, Atlas initiates the research process by invoking `websearch`. This tool is designed to intelligently locate relevant documentation pages. For instance, if you're integrating a payment gateway, you might prompt Atlas with 'find documentation for Stripe API latest version'. Atlas's `websearch` capability is permission-gated, meaning it will always ask for your explicit approval before making any external requests, displaying the search query it intends to use. This ensures transparency and control, preventing any unintended data exfiltration. Once approved, Atlas will present a list of potential URLs, allowing you to select the most authoritative source for your Echo integration. ## How Atlas fetches and reads API specifications for Echo After identifying the correct documentation URL, Atlas fetches the content using its `webfetch` tool, which can negotiate formats like Markdown or plain text. This ensures that in 2026, you receive a compact, readable representation of the API, making it easier to parse and understand the external service's contract. With a target URL identified, Atlas proceeds to retrieve the actual documentation content. The `webfetch` tool is employed for this purpose. To optimize for readability and efficient processing, Atlas can specify `Accept` headers to steer the server towards returning content in `markdown` or `text` format, rather than complex HTML. This is particularly useful for quickly extracting endpoint paths, request/response schemas, and authentication methods relevant to your Echo handler. Before `webfetch` executes, Atlas presents a permission prompt, showing the exact URL it intends to access. This critical security measure ensures that no external requests are made without your explicit consent, safeguarding your development environment. Once the content is fetched, Atlas can then parse and contextualize this information, preparing to assist in writing the Echo integration code, such as defining custom binders or `echo.Group` routes. ## How Atlas integrates external APIs into Echo applications After researching an external API, Atlas assists in writing the integration code for your Echo application, focusing on idiomatic Echo patterns. It can draft handlers that return `echo.NewHTTPError` instead of inline status codes, and suggest custom `Validator` implementations, ensuring your 2026 codebase remains consistent and robust. Once Atlas has a clear understanding of the third-party API's shape from the fetched documentation, it transitions to the integration phase. Using its `write` or `edit` tools, Atlas can generate or modify Go code within your Echo project. This includes drafting new `echo.Group` routes, defining middleware order, and implementing handlers that correctly interact with the external service. Atlas is specifically trained to adhere to Echo's conventions, such as returning `echo.NewHTTPError` for error conditions rather than embedding raw status codes, which centralizes error handling through your custom `HTTPErrorHandler`. It can also propose adding a custom `Validator` to ensure incoming request payloads conform to the external API's requirements. After drafting the code, Atlas can generate `go test (httptest)` coverage for the new handlers, behind a permission prompt, ensuring the integration is robust and verifiable within your existing test suite. This iterative process allows for rapid development while maintaining high code quality. ## Verifying and committing Echo API integrations with Atlas Before finalizing any API integration in Echo, Atlas ensures the new code adheres to your repository's conventions and is properly formatted. It uses `grep` to verify patterns and `gofumpt` to maintain code style, providing a unified diff for approval before any changes are written to disk in 2026. After Atlas drafts the Echo integration code and potentially generates tests, a crucial verification step follows. Atlas uses its `grep` tool to scan your existing codebase, ensuring that the newly written integration adheres to established patterns and conventions within your repository. For example, it might check for consistent error handling practices or specific logging idioms. This prevents the introduction of code that deviates from your team's standards. Furthermore, Atlas will propose running `gofumpt` over the touched packages to ensure all new or modified Go files conform to the project's formatting rules. Every proposed change, from new handler logic to test cases and formatting adjustments, is presented as a unified diff. This diff is surfaced for your explicit approval, giving you complete control over what gets written to your files. Atlas can also read `git` branches, status, and diffs, and can stage and create commits on your behalf, streamlining the entire development workflow from research to a fully committed, verified Echo integration. ## Steps 1. Run Atlas in your Echo module whose `go.mod` requires `github.com/labstack/echo/v4`. 2. Ask Atlas to `websearch` for the current documentation page of the third-party API, for example: "Atlas, `websearch` for 'Stripe API documentation 2026'". Approve the permission prompt. 3. Instruct Atlas to `webfetch` the identified documentation URL, passing `format markdown` or `text` to get a compact representation. Approve the `webfetch` permission prompt with the URL pattern. 4. Ask Atlas to `write` or `edit` your Echo handlers, incorporating the API's signatures. Let Atlas return `echo.NewHTTPError` from a handler instead of writing a status code inline. 5. Let Atlas add a custom `Validator` and cover the handlers with `go test` using `httptest`, behind a permission prompt. 6. Ask Atlas to `grep` your codebase to ensure the new integration adheres to your repository's existing Echo conventions. 7. Review the unified diff presented by Atlas for all proposed file edits, including new `echo.Group` routes and handler logic, and approve the changes. 8. Let Atlas run `gofumpt` over the touched packages to ensure all Go files are correctly formatted. 9. Allow Atlas to stage and create a `git` commit for the verified and formatted Echo integration. ## FAQ ### How does Atlas ensure API documentation is up-to-date for Echo?
