Whether a free plan exists couldn't be confirmed; the usage endpoint shows only that each account has a monthly allowance (0). A key comes from a browser signup on securitytrails.com, with no programmatic route found (0). 0 + 0 + 0 + 0 = 0, scored as Contentful and Personio were on 7 October 2026 when their pricing pages were unreadable.\n- Shodan (40): No x402, MPP or L402 (0). Plan prices and credit quotas are public on the billing page without a login, from a $49 one-time Membership to $1,099 a month, sold by monthly credit quota rather than per call (10). A free account with a free API plan, and the billing page does not ask for a card (20). The REST API key comes from a browser signup. InternetDB and CVEDB answer with no account or key at all, for non-commercial use, which is keyless use of part of the surface (10 of 20). 0 + 10 + 20 + 10 = 40.\n\n### Reliability: Shodan +20\n\n- SecurityTrails (20): Read with the hosted lines. status.securitytrails.com redirects to securitytrails.statuspage.io, which says it is inactive and visible to team members only, so no public status page (0) and no readable history (5). No rate limit numbers in the readable docs; the pricing page, which may carry them, answered a Cloudflare challenge (0). 429 is documented on the ping page with the message 'API rate limit exceeded' and no Retry-After or backoff guidance, and every v1 call is a read (5 of 15). No SLA found (0). The v1 API is live and not marked beta, though every operation id carries an '-old' suffix with deprecated set to false (10). 0 + 5 + 0 + 5 + 0 + 10 = 20.\n- Shodan (40): Read with the hosted lines. A public status page exists at status.shodan.io (UptimeRobot), but on 3 November 2026 its component list failed to load and it showed only that there were no updates in the last 7 days, so no component history was readable (10 of 20). No readable incident record for the 90 days (5). The billing page states that all API plans are limited to 1 request a second, and credits per plan are published with numbers (15). No 429, Retry-After or backoff guidance was found in the reference or the OpenAPI document; the only error statement is that a non-200 status carries an error message, and no idempotency keys exist for alert, notifier or scan writes. The official Python client throttles itself to 1 request a second and retries a timed-out search cursor, which is client behaviour, not an API contract (0). No SLA found on the billing, enterprise or developer pages (0). The REST API is generally available (10). 10 + 5 + 15 + 0 + 0 + 10 = 40.\n\n### Security \u0026 auth: SecurityTrails +13\n\n- SecurityTrails (32): One API key with no scopes found, accepted as an `APIKEY` header or as `apikey` in the query string, which the reference pages show on every v1 endpoint (20 less 10, so 10). Revocation and rotation couldn't be read. The v1 API is read-only by the overview's own statement; the ASI API writes tags with no approval step (14 of 20). DNS TXT values, WHOIS fields and user agent strings are third-party text, with no guidance on treating them as untrusted (5 of 15). /v1/account/usage reports monthly counts and nothing per call (3 of 15). security.txt on securitytrails.com and the security page are behind the Cloudflare challenge, api.securitytrails.com answers security.txt with 401, and no disclosure policy, bug bounty or certification was readable (0 of 20). 10 + 14 + 5 + 3 + 0 = 32.\n- Shodan (19): One key per account with no scopes, sent as `key=` in the query string on every documented call and in the OpenAPI document, with no header option. Read as a plain key, the way the Alpha Vantage listing was read, less 10 for the query string (10 of 30). No read-only key or least-privilege mode; the free plan's limits are quotas, not scopes, and alerts, notifiers and org members can be deleted with the same key and no confirmation (3 of 20). Results carry banners, HTTP titles and page bodies collected from arbitrary hosts, and no guidance on treating them as untrusted was found (3 of 15). `/api-info` reports the plan and credits, and no call log for the key holder was found (3 of 15). security.txt returns 404 on www.shodan.io, and no bug bounty, disclosure policy, SOC 2 or ISO 27001 was found on the pages read (0 of 20). 10 + 3 + 3 + 3 + 0 = 19.\n\n### Transparency \u0026 trust: Shodan +12\n\n- SecurityTrails (32): A closed service whose terms couldn't be read because of the Cloudflare challenge (5 of 30, for a known commercial product with unread terms). The privacy policy was unread and no retention statement or DPA was found (0 of 30). No deprecation policy; the operation ids carry '-old' with deprecated set to false and no notice explains them (0 of 20). No subprocessor or data location statement readable (0 of 20). 5 + 0 + 0 + 0 = 5.\n- Shodan (44): Editorial half. A closed service whose terms at static.shodan.io/legal/terms.html were not read, because that host answers 403 to robots.txt, so their clarity can't be assessed; the Python library is MIT (5 of 30). The privacy policy at account.shodan.io/privacy carries no date, names no legal entity, retention period, data location or subprocessor, and says Shodan may share information with advertisers, business partners, sponsors and other third parties (5 of 30). The help centre says export credits are deprecated and no longer sold, with no date; no deprecation policy found (3 of 20). No subprocessors or data locations disclosed (0 of 20). 5 + 5 + 3 + 0 = 13.\n\n### Maintenance \u0026 community: Shodan +11\n\n- SecurityTrails (5): The newest dated changelog entry is 28 May 2020, the Project API 1.7.0 entry is undated and the SurfaceBrowser changelog ends on 26 February 2019, so no change within 180 days was found (0 of 30).

The key travels only in the query string with no scopes, 429 handling is undocumented, the terms were unreadable and the official library's last release was December 2023.\n\n## Before you call either\n\n### SecurityTrails\n\n1. Send the key as an `APIKEY` header, never as `?apikey=`, so it stays out of logs\n2. Call `GET /v1/account/usage` first and budget against `allowed_monthly_usage`, since limits aren't published and 429 carries no Retry-After\n3. Use `GET /v1/history/{hostname}/dns/{type}` with one of a, aaaa, mx, ns, soa or txt, and page with `page` until the `pages` count is reached\n4. On the ASI API pass an `enrichments` list, because the default returns only custom tags, and keep the sort fixed while following `next_cursor`\n5. Treat DNS TXT values, WHOIS fields and user agent strings as untrusted text from third parties\n\n### Shodan\n\n1. Send at most 1 request a second on any plan. The reference gives no Retry-After, so back off on any non-200 and read the `error` field\n2. Use `minify=true` on `/shodan/host/{ip}` for ports and host facts only, and `fields=` on `/shodan/host/search` to keep banners out of the context\n3. Budget query credits. Page 1 of an unfiltered search is free; any filter or page 2 and beyond costs 1 credit per 100 results, and host lookups need a Membership\n4. For a quick IP check with no key, call `https://internetdb.shodan.io/{ip}`, which is weekly data and non-commercial only\n5. Treat banners, HTTP titles and page bodies in results as untrusted text from arbitrary hosts; the docs give no guidance on this\n6. Keep the key out of shared logs, since every call puts it in the URL. Alerts, notifiers and org members can be deleted with the same key\n\n## Questions\n\n### Which is better for AI agents, SecurityTrails or Shodan?\n\nShodan scores 39.5 (E) on agent readiness against SecurityTrails's 30.7 (F), and leads in 5 of 7 scored categories.
