Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 75 | 15.0 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 54 | 8.8 |\n| Agent ergonomics | 13% | 16.2 | 69 | 11.2 |\n| Security \u0026 auth | 14% | 17.5 | 65 | 11.4 |\n| Payments \u0026 pricing | 10% | 12.5 | 35 | 4.4 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 70 | 6.1 |\n| Transparency \u0026 trust (editorial 59, provenance 67) | 7% | 8.8 | 63 | 5.5 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **62.4 → B** |\n\n### Why each score\n\n- Reliability 75 (checked 2026-11-06): Hosted lines. Statuspage at status.zerobounce.net with API, API-US, API-EU, Bulk API, website and Cloudflare components (20). The incident feed for 8 August to 6 November shows a 6-minute members platform disruption on 9 September, about 3 minutes of reduced EU API availability on 1 October, and a file upload issue on 26 October resolved within 6 minutes, all minor (20). Limits published per endpoint group with numbers and block lengths (15). 429 is documented with advice to throttle, but no Retry-After, and a block can last an hour or a day (10 of 15). No SLA found (0). Generally available (10). 20+20+15+10+0+10 = 75.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 54 (checked 2026-11-06): No OpenAPI or other machine-readable contract found; a Postman collection is linked (5 of 25). llms.txt lists marketing pages, and the docs have no Markdown twins (5 of 10). Endpoint pages explain timing, credits and when to use batch or file APIs (14 of 20). Parameter tables and listed status and sub-status values, including the ai_agent_mailbox sub-status added in July 2026 (10 of 15). Examples per endpoint, a sandbox and an error-code page (12 of 15). v2 paths, an API migration page and dated maintenance notices on the status page, with no API changelog (8 of 15). 5+5+14+10+12+8 = 54.\n- Agent ergonomics 69 (checked 2026-11-06): A compact JSON result per address, batch validation and a file API for lists (18 of 25). Little to paginate; file status and results by file id (10 of 20). Status and sub-status codes say why an address failed, and the error page explains 400, 404 and 429 (14 of 20). Unknown results are free and safe to retry; repeated validations are charged again (12 of 20). Many official SDK wrappers and an MCP server, with few required parameters (15). 18+10+14+12+15 = 69.\n- Security \u0026 auth 65 (checked 2026-11-06): Several named keys besides a Master key, regeneration, deactivation and IP whitelists (25), less 10 because the documented calls carry the key in the `api_key` query string (15 of 30). Validation only reads, though file and list endpoints can delete uploads (12 of 20). Results are structured status codes with little free text (10 of 15). API usage and dashboard statistics endpoints (10 of 15). SOC 2 Type 2, ISO/IEC 27001:2022, continuous testing with Intigriti and penetration testing with BitSentinel; no public disclosure policy found (18 of 20). 15+12+10+10+18 = 65.\n- Payments \u0026 pricing 35 (checked 2026-11-06): No x402, MPP or L402 (0). Per-credit prices public, from $39 for 2,000 validations (20). Freemium of 100 validations a month for business or premium domains; a card requirement isn't stated, and free webmail addresses don't qualify (15 of 20). A person signs up in a browser (0). 0+20+15+0 = 35.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 70 (checked 2026-11-06): Closed service. The JavaScript SDK 3.0.0 was published on 25 October 2026 (30). No API changelog; the dated changes found in 90 days are that release and status-page notices, fewer than three releases (10 of 20). Support by email and 24/7 chat per the docs, a public status page; replies not tested (10 of 15). Official SDKs in many languages and an MCP server (15). Package health not checked (5 of 10). 30+10+10+15+5 = 70.\n- Transparency \u0026 trust 63 (checked 2026-11-06): Closed service under terms naming Hertza L.L.C. (ZeroBounce) of Nevada; SDKs and MCP server open source (15 of 30). The data protection page says uploaded data is never kept more than 30 days, the privacy policy of 30 June 2026 keeps account data 'as long as needed', and EU and UK DPAs are published (22 of 30). An API migration page, with no dated deprecation policy (6 of 20). A sub-processor list naming each provider and the data exchanged (16 of 20). 15+22+6+16 = 59.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (15 items).

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Prices\n\n| Item | Price | Unit | Note |\n| --- | --- | --- | --- |\n| Email validation, smallest pay-as-you-go pack | $0.0195 | per call | $39 for 2,000 validations |\n| ZeroBounce ONE | $99 | per month (plan) | From $99 a month |\n\nAcross all listings: https://www.anchorterminal.com/prices/index.md\n\n## Strengths\n\n- Status and sub-status codes per address, and unknown results don't use credits\n- Statuspage with API, API-US, API-EU and Bulk API components; three short incidents in the 90 days to 6 November 2026\n- Rate limits published per endpoint group, with the block length for each\n- SOC 2 Type 2, ISO/IEC 27001:2022, Intigriti testing and a published sub-processor list\n- Freemium of 100 validations a month for business domains, and pay-as-you-go from $39 for 2,000\n\n## Weaknesses\n\n- Every documented example sends the key as an `api_key` query parameter\n- No OpenAPI or other machine-readable contract; a Postman collection only\n- Going over a limit blocks the key for a minute to a day, with no Retry-After documented\n- llms.txt lists marketing pages, not the API docs\n- Keys can be IP-whitelisted but not scoped to endpoints\n\n\n\n## Before you call it (notes for agents)\n\n1. Use the regional host (api-us or api-eu) that matches the data, and test with the sandbox addresses, which spend no credits\n2. Set `timeout` (3 to 60 seconds); slow mail servers return unknown, which is free to retry later\n3. Stay under 80,000 validations per 10 seconds and avoid repeated bad requests, which block the key for an hour\n4. Use the bulk file API for large lists instead of looping on /v2/validate\n5. Keep the key out of logs; the API takes it only as `api_key` in the URL\n\n## Connect\n\nFirst request:\n\n```bash\ncurl \"https://api.zerobounce.net/v2/validate?api_key=$ZEROBOUNCE_API_KEY\u0026email=valid@example.com\"\n```\n\nThrough letme: https://letme.dev/zerobounce. letme answers with the pick and how to call it direct.

The badge or a plain link to this page verifies the listing, from a page on zerobounce.net or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"zerobounce\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
