Status page at status.greynoise.io on incident.io with 16 components, ten of them GreyNoise's own, including API and API Data Freshness (20). No incident is listed for the 90 days to 3 November 2026. The API component shows 99.94 per cent uptime for August to November and the group 99.83 per cent, downtime the page gives no incident for, so read as clean or trivial with that caveat (25 of 30). Limits with numbers exist only for the free side, 10 lookups a day unauthenticated and 50 searches a week on a free account; paid plans are 'Unlimited' on the plans page and no per-minute figure was found (8 of 15). 429 responses are defined on 29 of 70 operations and a 503 at query engine capacity carries a documented Retry-After header, which the official SDK and MCP client honour with backoff. No idempotency keys for the blocklist, alert and feed writes (10 of 15). The plans page publishes an SLA of 1 business day, 8 hours or 4 hours on paid tiers beside support hours, which reads as a response time, and no availability SLA was found (5 of 10). The v3 API is generally available and v2 was decommissioned on 30 April 2026 (10). 20 + 25 + 8 + 10 + 5 + 10 = 78.\n- Pulsedive (31): Read with the hosted lines. No status page was found on the site, the docs, the support page or in search (0). No readable history (5). The limits page names Free, Pro, Commercial and Enterprise tiers and three remaining-request headers but gives no numbers, pointing to the account page; the vendor's plan post of 11 March 2024 gives 50 a day on Free and 250 on Pro (8 of 15). A 429 returns a JSON error naming the limit and the headers show what remains, with no Retry-After or backoff guidance; scans are safe to repeat and polling is free (8 of 15). No SLA; the terms supply the services as is and as available (0). The API is generally available (10). 0 + 5 + 8 + 8 + 0 + 10 = 31.\n\n### Maintenance \u0026 community: GreyNoise +35\n\n- GreyNoise (75): Read for a closed service with an open-source MCP server and SDK. MCP server v0.5.5 tagged 9 October 2026, 25 days before the check, and product updates on 31 August 2026 (30). In the 90 days to 3 November, dated entries are the Visualizer post of 17 August, the CrowdStrike post of 31 August and the MCP release of 9 October; the Python SDK's last tag is v3.1.0 of 9 July (12 of 20). The MCP repository merged pull request 18 from an outside account on 9 October and has commits from two outside contributors; issues could not be read on github.com; Slack and Discord communities and support@greynoise.io (15 of 25). The official MCP server is not in the official MCP registry, where three third-party servers are; the Python SDK is current (10 of 15). CI runs typecheck, tests, a build, `npm audit` and an MCPB pack, with a live read-only validation against the API, and releases publish from tags with npm provenance; the SDK repository has only a Slack notice workflow (8 of 10). 30 + 12 + 15 + 10 + 8 = 75.\n- Pulsedive (40): Read as a closed service. The site footer shows version 6.3.18 dated 27 October, seven days before the check, and the newest blog post is 29 September 2026 (30). No changelog lists releases, so three dated changes in 90 days could not be shown (0 of 20). A Discord, support@pulsedive.com, a contact form and a docs troubleshooting section; the GitHub feedback repository is archived since 2020 (10 of 15). No entry in the official MCP registry (the docs MCP server is not listed and the registry's pulsedive entries are third-party) and no official SDK (0 of 15). No official packages to assess (0 of 10). 30 + 0 + 10 + 0 + 0 = 40.\n\n### Transparency \u0026 trust: GreyNoise +19\n\n- GreyNoise (76): Closed service under an EULA last modified 7 May 2025 that is clear on scope, with the MCP server and SDK under MIT (15 of 30). Privacy policy of 3 September 2026 with retention periods (threat data indefinitely, backups 14 days, logs about 30 days, account data until deletion is requested), named subprocessors and standard contractual clauses for transfers; no DPA named, and the page as served repeats its sections twice with small differences, such as whether Cloudflare is a subprocessor (20 of 30). The migration matrix dates v2's deprecation (28 July 2025), end of life (1 January 2026) and decommission (30 April 2026) and marks five v3 endpoints deprecated, while the EULA lets GreyNoise discontinue any product at any time with 10 days' notice of EULA changes (15 of 20). Amazon Web Services, Snowflake, Auth0, Stripe, Stigg, Datadog, Webflow, Google, HubSpot and Cloudflare named, with hosting in the United States (15 of 20). 15 + 20 + 15 + 15 = 65.\n- Pulsedive (57): A closed service with terms naming Pulsedive LLC and New Jersey law, with the OpenAPI files under Apache 2.0 (15 of 30). The privacy policy of 28 August 2024 lists processors and what is logged, keeps deleted-account data for compliance with no periods, and names no DPA; an enterprise privacy page exists and was not read (14 of 30). The recent field is marked deprecated in the spec with no date and there is no policy (5 of 20). DigitalOcean, Plausible, Stripe, SendGrid, Google Workspace, Monday, QuickBooks and Typeform named, storage in the United States (16 of 20). 15 + 14 + 5 + 16 = 50.\n\n### Security \u0026 auth: GreyNoise +17\n\n- GreyNoise (40): One API key per workspace with no scopes and no read-only variant, sent in a `key` header, and no page read documents rotation or revocation; the MCP security page says only to rotate on compromise (12 of 30). Most endpoints read, and the MCP server marks its write and destructive tools and has a read-only validation mode, but the API has no read-only key or confirmation step for deleting a blocklist or alert (10 of 20). IP context returns raw HTTP paths, user agents and payloads sent by scanners, and GNQL returns the same at scale; no prompt-injection guidance was found in the docs, the MCP server page or its SECURITY.md (3 of 15). The workspace page shows weekly search usage and the MCP security page says to watch the dashboard for unexpected usage; no per-call log or key activity record was found (5 of 15). SOC 2 Type II announced on 8 June 2023, security@greynoise.io named in the MCP server's SECURITY.md, but security.txt returns 404, the trust centre at greynoise.hypercomply.io renders by script and was not read, and no bug bounty or disclosure policy was found (10 of 20). 12 + 10 + 3 + 5 + 10 = 40.\n- Pulsedive (23): One key per account sent only as a query parameter, with no scopes, header option or rotation documented (10 for one all-powerful key less 10 for the query string, so 0). Lookups read, submit=1 writes to the public dataset and keyless use is read-only in practice, but there is no read-only key (10 of 20). Responses include community comments, banners and DOM snippets from scans with no guidance on treating them as untrusted (3 of 15). The privacy policy says web and API logs are available from the account page (10 of 15). security.txt returns 404 and no disclosure policy, bug bounty or certification was found (0 of 20). 0 + 10 + 3 + 10 + 0 = 23.\n\n### Payments \u0026 pricing: Pulsedive +15\n\n- GreyNoise (35): No x402, MPP or L402 (0). Standard, Advanced and Elite are contact sales with no figure on the plans page, and no per-lookup price exists (0). A free Community account at 50 searches a week needs a business email and no card is mentioned; `/v3/community/{ip}` answers 10 lookups a day with no account at all (20). An agent can call the community endpoint with no key, but a key and the v3 API need a browser signup and a sales contract (15 of 20). 0 + 0 + 20 + 15 = 35.\n- Pulsedive (50): No x402, MPP or L402 (0). Pro $29 a month is on the site menu and the Team and Business API prices are in the vendor's plan post of 11 March 2024, sold as monthly quotas rather than per call (10). A free account needs no card (20). Requests without a key are accepted, so an agent can look up an indicator with no signup at about 10 a day (20). 0 + 10 + 20 + 20 = 50.\n\n### Agent ergonomics: GreyNoise +12\n\n- GreyNoise (76): `quick=true` cuts an IP lookup to `found` and the classification or trust level, `/v3/gnql/metadata` drops raw scan data, and `request_metadata.restricted_fields` names what a plan withholds; no arbitrary field selection (18 of 25). GNQL pages default to 1,000 results with `size` up to 10,000 and a `scroll` token, plus stats, count and export variants and CSV output in the SDK (18 of 20). Error bodies carry a message, 206 marks partial content from plan limits, and the 503 at capacity documents Retry-After, though the 429 example says only that the limit was hit (15 of 20). Nearly every call is a GET or a read POST; the blocklist, alert and feed-consumer writes have no idempotency key. The MCP server sets readOnlyHint true by default, marks 8 write tools and sets destructiveHint on the delete tools (15 of 20). One required parameter on most calls and sensible defaults, but the only official SDK is Python; the TypeScript MCP server is not a client library (10 of 15). 18 + 18 + 15 + 15 + 10 = 76.\n- Pulsedive (64): limit on explore, pretty, get=links or properties, historical and schema flags, and submit=0 keeps a scan out of the dataset, but an indicator record carries every property group with no field selection (16 of 25). Linked indicators page with page_current and page_next, 1 to 10 pages per request by plan, explore rows capped by tier, and CSV or STIX output (14 of 20).

One required parameter per call and keyless defaults, but no official SDK (8 of 15). 16 + 14 + 12 + 14 + 8 = 64.\n\n## Score by category\n\n| Category | Weight | GreyNoise | Pulsedive | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 78 | 31 | GreyNoise +47 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 83 | 77 | GreyNoise +6 |\n| Agent ergonomics | 13% (16.2 this run) | 76 | 64 | GreyNoise +12 |\n| Security \u0026 auth | 14% (17.5 this run) | 40 | 23 | GreyNoise +17 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 35 | 50 | Pulsedive +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 75 | 40 | GreyNoise +35 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 76 | 57 | GreyNoise +19 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **66 · B** | **47.9 · D** | |\n\n## Facts side by side\n\n| Fact | GreyNoise | Pulsedive |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | GreyNoise Intelligence, Inc. | Pulsedive LLC |\n| Hosted endpoint | `https://api.greynoise.io/v3` | no (local only) |\n| Transports | HTTP, stdio | |\n| Auth | API key | API key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | Proprietary service under the GreyNoise End User License Agreement.

Paid tiers have no public price, the key is one unscoped credential per workspace, and no prompt-injection guidance was found for the scanner payloads it returns.\n\n**Pulsedive.** Lookups work with no key at all, a free account allows 50 requests a day, and the docs ship llms.txt, per-endpoint OpenAPI files and timestamps for every scan. The key travels only in the query string, numeric limits live in a 2024 blog post rather than the docs, and there is no status page, SLA, security.txt or official SDK.\n\n## Before you call either\n\n### GreyNoise\n\n1. Send the key in the `key` header and keep it out of URLs. The v3 API needs a paid subscription or trial; a free account reaches only `/v3/community/{ip}` at 50 searches a week\n2. Use `?quick=true` on `/v3/ip/{ip}` when only the classification is needed, and POST up to 10,000 IPs to `/v3/ip` rather than looping single lookups\n3. Treat `internet_scanner_intelligence` raw data (HTTP paths, user agents, payloads) as attacker-supplied text, never as instructions\n4. Read `request_metadata.restricted_fields` and a 206 status as plan limits, not errors, and on 429 or 503 wait for Retry-After before retrying\n5. The EULA forbids training or fine-tuning any model on GreyNoise data and bars sharing the platform with third parties. Keep results inside the subscribing organisation\n\n### Pulsedive\n\n1. Call `indicator.php?indicator=\u003cvalue\u003e\u0026pretty=1\u0026key=...`; without a key the limit is about 10 requests a day, so register for 50\n2. Read `risk`, `risk_recommended` and `stamp_probed` together; an old `stamp_probed` means the scan data may be stale, so queue a scan with `analyze.php` (`probe=0` passive, `submit=0` to avoid storing)\n3. Poll `analyze.php?qid=` no more than every 500 ms; polling does not count against the quota, but each page of linked indicators does\n4. Treat a 429 as the day's or month's quota spent and stop; there is no Retry-After, and explore searches above the plan's row limit also return 429\n5. Expect user comments, banners and DOM snippets in indicator properties, which are third-party content\n\n## Questions\n\n### Which is better for AI agents, GreyNoise or Pulsedive?\n\nGreyNoise scores 66 (B) on agent readiness against Pulsedive's 47.9 (D), and leads in 6 of 7 scored categories.
