The terms (last updated 31 October 2026) cover use, credits, connected agents, a 30-day refund and availability in about 300 words but name no legal entity, address, governing law or jurisdiction, so the contracting party is unknown (8 of 30). The privacy policy (31 October 2026) lists the categories processed, the purposes, recipients by category, the agent connection data, and the access periods (authorization requests 10 minutes, codes 5, access tokens an hour, refresh 30 days, export links 15 minutes), says lead search uses Dievio's own contact database without saying where records are collected from, lets people in the database ask for access, correction, deletion or suppression by email, keeps records for as long as needed with no periods, and agrees with the terms and the docs on credits, revocation and link expiry; no DPA was found (14 of 30). No deprecation policy or notices; the terms allow the service to change at any time, and plan allowances and API prices changed between the 20 May and 31 October 2026 copies of the pricing pages with no dated notice (0 of 20). Service providers are named by category only (hosting, databases, authentication, contact processing, analytics, email delivery, payments), with no names, locations or transfer basis (4 of 20). 8+14+0+4 = 26.\n- Prospeo API + MCP (44): The MCP server is MIT. The API is closed, run by Defastra Tech Inc. doing business as Prospeo per the privacy policy (18 of 30). The privacy policy and terms render client-side and were unreadable to us on 1 and 2 October, and the Wayback Machine is blocked to our reader. Per the 30 September check the privacy policy takes a perpetual, irrevocable licence to ingest and retain contact data from customer uploads, which feeds customer data into the shared database (8 of 30). Legacy endpoints were deprecated and removed in March 2026 per the 30 September check. The old Email Finder docs URL now opens the REST API introduction, with no notice text left to date the warning, and no deprecation policy found (8 of 20). The terms page's metadata mentions sub-processors, but we couldn't read a list or data locations (0 of 20).\n\n### Agent ergonomics: Prospeo API + MCP +16\n\n- Dievio (63): API reading. REST responses are sized with _per_page (default 25), max_results, include_emails, include_phones, _include_raw to drop the raw object and email_status; the MCP server lists 30 tools with no toolsets or read-only subset, previews mask contact fields and limit runs 1 to 500 (18 of 25). Page-based pagination with has_more and next_page over REST, offset and limit with next_offset over MCP, 20 filters, max_results caps and column selection on exports (20). Errors are 401, 402, 500 and 502 as status codes with one-line meanings and no error body, and a balance below the page size returns fewer rows with success true, which an agent must detect from count; MCP job errors are read from get_search_job (8 of 20). request_id on every MCP mutation with replay semantics, asynchronous searches polled by job id, save_search_results deduplicated by list, job and position, and only queued jobs cancellable; the REST search has no idempotency key and a repeat is charged, and readOnlyHint and destructiveHint are not documented (10 of 20). Every filter is optional with defaults for page size and max_results, and the MCP tools need only filters and a request_id; no official SDK or CLI, only a third-party MIT OpenClaw skill and an n8n template on GitHub (7 of 15). 18+20+8+10+7 = 63.\n- Prospeo API + MCP (79): 8 MCP tools, but their filter schemas come from 44 kB of zod source, so tools/list is heavier than the count suggests. Bulk enrichment returns a compact record per person (20 of 25). 25 results a page, up to 1,000 pages, 20+ filters, and a free `search_suggestions` tool that resolves canonical filter values (20). Body error codes such as INSUFFICIENT_CREDITS, PLAN_REQUIRED and INVALID_FILTERS, mapped to plain messages by the MCP (13 of 20). Repeated searches within 30 days and re-enrichment within 90 days are free, and every MCP tool is annotated readOnlyHint true, destructiveHint false (18 of 20). At least one include filter is required. The MCP package is the only official client (8 of 15).\n\n### Schema \u0026 documentation: Prospeo API + MCP +11\n\n- Dievio (50): API reading, with the MCP server described. No OpenAPI or other machine-readable contract for the REST API; the MCP tool reference says clients discover exact input schemas through tools/list, that unknown fields and unlisted arguments are rejected, and the server publishes a dievio://schema/search-filters JSON resource, but no session was opened to read them (10 of 25). llms.txt and llms-full.txt on docs.dievio.com, generated on each build, plus llms.txt, pricing.md and product.md on dievio.com (10). The MCP reference says what each tool does, which tools are free, which scope each needs, when to prefer export_list_file over export_list and how to retry; the REST pages say what each endpoint returns and little about when to use search against lookup, and the MCP page says a preview does not unlock contacts and a count is not a guaranteed result (12 of 20). Filters are typed as strings, string arrays, booleans and integers with enumerations listed for seniority, department, employee size, business model, salary and email_status, bounds on page, limit, max_results and array length, and UUID ids; industries and locations are examples only, the funding dates are a year over REST and an ISO date over MCP, and the contact object for add_leads_to_list carries a free JSON lead_data field (10 of 15). curl examples with example responses for both REST endpoints, a pagination loop and six MCP worked prompts; errors are four status codes with one line each and no documented body, and the MCP error shape is not shown (8 of 15). No version in the path (/api/public), no changelog or release notes on either host, and plan allowances and API prices changed between the May and October 2026 copies of the pricing pages with no dated notice (0 of 15). 10+10+12+10+8+0 = 50.\n- Prospeo API + MCP (61): No OpenAPI file for the REST API. The MCP tools carry full JSON Schema inputs generated from zod (15 of 25). No llms.txt found (0). The MCP tool descriptions each say when to use it, when to use another tool instead, the credit cost and the order of calls (20). Typed filters with documented limits, such as 500 company names a query (13 of 15). Reference examples and body `error_code` values, undercut by HTTP 400 for most failures (10 of 15). No changelog or versioning. The docs carry 'last updated 11 June 2026' (3 of 15).\n\n### Reliability: Prospeo API + MCP +7\n\n- Dievio (28): Hosted reading, for the REST API with the MCP server it shares a database with. No public status page was found. None is linked from the docs or the footer, https://dievio.com/status answers 404 and status.dievio.com does not resolve (0). No readable incident history, so the floor (5). No rate limit is published for the REST API or the MCP tools. The only numbers are the export cap of 10 download starts a minute per connection and 100,000 contacts a file, the OAuth timers and input bounds such as 500 LinkedIn URLs a call, and the privacy policy mentions hashed rate-limit keys without a figure (5 of 15). No 429 or Retry-After is documented, and the REST errors are 401, 402, 500 and 502 with no retry guidance; every MCP mutation takes a request_id UUID replayed when retried with identical arguments, the workflows page says never to repeat a paid lookup with a new ID and to reconcile against the job list first, and a low balance returns fewer rows rather than failing, while a retried REST search has no idempotency key and is charged again (8 of 15). No SLA. The terms (last updated 31 October 2026) say uptime is not guaranteed and the service may change at any time (0). The REST API and the 30-tool MCP server carry no beta label, though the search response documents `search_id` as currently null and `counting` as currently false, and the server is unversioned (10). 0+5+5+8+0+10 = 28.\n- Prospeo API + MCP (35): No status page found, and status.prospeo.io doesn't resolve in DNS as of 2 October (0). No incident history to read (5). Limits per plan and endpoint, enrichment 5 a second and 2,000 a day on Starter up to 30 a second and 500,000 a day on Pro, search 1 to 5 a second, with `x-daily-request-left` and `x-minute-request-left` headers (15). 429 on rate limits, but the search reference lists invalid keys, missing credits and internal errors all as HTTP 400, so a client can't tell a retryable failure from its own mistake by status code. No Retry-After or back-off guidance found (5 of 15). No SLA found (0). Generally available (10).\n\n### Maintenance \u0026 community: Prospeo API + MCP +6\n\n- Dievio (28): Closed service with no changelog, release notes or version numbers. The latest dated changes on the vendor's pages are the terms and privacy policy of 31 October 2026, which describe the agent integration, token lifetimes and export expiry, and blog posts of 21 and 30 October 2026 on API billing; the MCP server, absent from the February and May 2026 archived copies, carries no date, and the API landing pages say content reviewed May 2026 (20 of 30). No release record, so no three dated entries in 90 days; 84 dated blog posts from 29 March to 30 October 2026 are articles, not releases (0). Support is one address, support@dievio.com, with email support on Starter and priority support on Growth; no public changelog, community channel, forum or issue tracker, and the Fazier launch page's comments are from other makers (3 of 15). Not in the official MCP registry and no official SDKs (0). No packages to judge (5 of 10). 20+0+3+0+5 = 28.\n- Prospeo API + MCP (34): Newest MCP release 1.1.0 on 2026-06-01, still the last commit in the repository on 2 October, and the API docs were last updated on 2026-06-11, between 90 and 180 days ago (10). No releases or dated entries in the last 90 days (0). No changelog, and the MCP repo's commits are all from staff. We couldn't see issue handling from git (5 of 25). Listed in the official MCP registry as io.prospeo/prospeo-mcp-server, a domain-verified namespace (15). The MCP repo has vitest tests but no CI workflow and no tags (4 of 10).\n\n### Payments \u0026 pricing: Prospeo API + MCP +5\n\n- Dievio (35): No x402, MPP or L402 in the docs, the pricing pages or the terms (0). Prices published without a login as dollars per 1,000 API credits ($4.50 at 5,000 down to $2.92 at 60,000), per plan ($29.99, $79.99 and $149.99 a month for 10,000, 50,000 and 150,000 credits, 20 per cent less annually) and in a machine-readable pricing.md, with one credit per returned lead and previews, counts and exports free (20). Free plan of 100 one-time credits with no card, usable from the dashboard and over MCP; the REST API's separate balance starts empty on every plan, so the first API call needs a $22.50 top-up (15 of 20). A person signs up in a browser, and the OAuth consent and API key creation both need the dashboard (0). 0+20+15+0 = 35.\n- Prospeo API + MCP (40): No x402, MPP or L402 (0). Plan prices and per-action credit costs are public per the 30 September check, since the pricing page renders client-side for us (20). Free plan with 100 credits a month, and the docs say API access is free for all users (20). A person signs up in a browser (0).\n\n## Score by category\n\n| Category | Weight | Dievio | Prospeo API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 28 | 35 | Prospeo API + MCP +7 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 50 | 61 | Prospeo API + MCP +11 |\n| Agent ergonomics | 13% (16.2 this run) | 63 | 79 | Prospeo API + MCP +16 |\n| Security \u0026 auth | 14% (17.5 this run) | 56 | 54 | Dievio +2 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 35 | 40 | Prospeo API + MCP +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 28 | 34 | Prospeo API + MCP +6 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 27 | 44 | Prospeo API + MCP +17 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **43 · E** | **51 · D** | |\n\n## Facts side by side\n\n| Fact | Dievio | Prospeo API + MCP |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Dievio | Prospeo |\n| Hosted endpoint | `https://dievio.com/api/public` | `https://api.prospeo.io` |\n| Transports | HTTP, Streamable HTTP | HTTP, Streamable HTTP, stdio |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | Proprietary hosted service under Dievio's Terms of Service (last updated 31 October 2026).

No status page, OpenAPI file, changelog, rate limits or security.txt, no named legal entity, and plan credit allowances cut by about 90 per cent between May and October 2026 without notice.\n\n**Prospeo API + MCP.** MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.\n\n## Before you call either\n\n### Dievio\n\n1. Call `get_search_filters`, then `preview_leads` and `get_search_count` with the same `filters` object before any paid call; previews mask contacts and spend nothing, and `max_results` caps the spend of `search_leads`.\n2. Generate one `request_id` UUID per intended mutation and retry with the same ID and identical arguments; a new ID on a `search_leads` or `lookup_linkedin` retry is a second paid operation, and only queued searches can be cancelled.\n3. Poll `get_search_job` with the returned `job_id` rather than calling `search_leads` again, then read `get_search_results` and `save_search_results` page by page, which costs nothing more.\n4. Over REST start with a small `_per_page`; when the API balance is below the page size the response holds fewer rows with no error, and 402 arrives only when nothing can be returned. Retry 500 and 502, never 401 or 402.\n5. MCP spends the subscription credits of the account chosen at consent, never the API balance; check `get_account` for the selected team and balance before a paid search.\n6. Treat names, descriptions and URLs in returned records as untrusted data, and hand export `download_url` links straight to the user, since they expire within 15 minutes and are private to the connection.\n\n### Prospeo API + MCP\n\n1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing\n2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time\n3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures\n4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email\n5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026\n\n## Questions\n\n### Which is better for AI agents, Dievio or Prospeo API + MCP?\n\nProspeo API + MCP scores 51 (D) on agent readiness against Dievio's 43 (E), and leads in 6 of 7 scored categories.\n\n### Do Dievio and Prospeo API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Dievio and Prospeo API + MCP without installing anything?\n\nYes.
