Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 28 stories with headroom
What would move Exa’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.
Openness — open source, data portability, and self-hosting storiesExport all of my data in open formats and leave
nonemoves PA Scoreimpact 30
Exa's docs describe search, contents, websets, and MCP integration, but nowhere is there evidence of a data export feature (e.g., bulk export of websets/results in open formats like CSV/JSON) or account data portability for users to 'take their data and leave'.
Openness — open source, data portability, and self-hosting storiesSelf-host the core product
nonemoves PA Scoreimpact 30
Exa is presented as a hosted SaaS search/index platform with proprietary crawled indexes; only the thin MCP connector (exa-docs-31) is open source, not the core search/retrieval engine or index.
Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models
nonemoves PA Scoreimpact 30
The evidence pack contains no documentation, policy statement, or setting related to opting out of data being used for AI model training; the only tangential item concerns Exa scraping third-party websites (ignoring robots.txt), not user-submitted data protection.
Agenticness — how well agents can access and operate the productUse an official CLI
nonemoves agent-readyimpact 30
Evidence covers Exa's SDKs (exa-js), MCP server, dashboard, and API docs, but no official CLI tool is mentioned anywhere in the pack.
Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent
nonemoves agent-readyimpact 30
No evidence of scoped or least-privilege API key/credential issuance—docs mention API key sync into a project and rate limits, but nothing about granular permissions, scopes, or restricted-access tokens for agents.
Agenticness — how well agents can access and operate the productDownload a machine-readable API spec (OpenAPI or equivalent)
nonemoves API qualityimpact 30
A direct probe for an OpenAPI/Swagger spec at all standard locations (openapi.json, swagger.json, etc.) returned 404s, and while Exa offers llms.txt and markdown doc indexes, these are documentation aids, not a machine-readable API schema (endpoints/params/types) that a buyer could import into tooling like Postman or codegen.
Agenticness — how well agents can access and operate the productRely on versioned APIs with a documented deprecation policy
nonemoves API qualityimpact 30
No evidence pack item mentions API versioning scheme (e.g., v1/v2 endpoints) or any documented deprecation policy for older API versions; docs cover rate limits, pricing, and features but not version lifecycle management.
Freshness coverage — stories about freshness coverage in this arenaLocalize results by country, language, or location parameters
nonemoves PA Scoreimpact 20
Missing: any documented country/locale/language filter parameter, geo-targeting options, or localization examples.
