Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community NextBillion.ai +50

MapQuest 23

The newest dated product changes are two blog announcements on 16 July 2026 (the Geolocation API and a 10,000 by 10,000 async route matrix), 84 days before the check (20). Two dated entries in 90 days. The MCP guide's version 1.2 is dated 7 July 2026, 93 days before (0). No changelog. Support is by email, untested (3). The MCP registry returns no server for 'mapquest', and the only current SDKs are browser libraries with no dated releases found (0). No package to judge (0).

NextBillion.ai 73

MCP server 0.5.3 on 30 October 2026 (30). Eleven tagged MCP releases between 7 October and 30 October, adding hosted mode, truck routing and geometry tools (20). Support by email, a public MCP repository with a changelog, but no public API changelog (8). The MCP server isn't in the official MCP registry, and we didn't check the mobile SDK versions (7). The MCP repository runs CI with unit and end-to-end tests (8). 30+20+8+7+8 = 73.

Transparency & trust NextBillion.ai +27

MapQuest 31

Closed service. The only terms linked are System1's website terms of 26 February 2021, which allow personal, non-commercial use and do not mention the APIs. The plans page states the storage rule (5). The System1 group privacy policy of 5 July 2023 gives no retention periods and describes sale and sharing of personal information, while the plans page says 'we don't collect or sell user data' (8). No deprecation policy. Dated notices exist from 2018 only (5). The policy names categories of service providers, with no list or locations. The geocoding docs name TomTom for international queries (3).

NextBillion.ai 58

Editorial half only. Closed service under terms that name NextBillion.ai Pte. Ltd. and Singapore law, and an Apache-2.0 MCP server (18). The privacy policy keeps personal data while a legitimate business need exists, with no periods given. The MCP README says only tool arguments are sent to the API and nothing is retained between requests (14). No deprecation policy or dated notices found. The terms promise 10 days' notice of material changes to the terms (3). Data is mainly processed in Singapore, with transfers abroad under standard clauses. No sub-processor list found (8). 18+14+3+8 = 43.

Schema & documentation NextBillion.ai +26

MapQuest 47

https://developer.mapquest.com/openapi.json describes the marketing site and has an empty paths object, so the product APIs have no machine-readable contract. The MCP tool definitions sit behind OAuth and were not read (0). llms.txt indexes every API with a one-line purpose (10). The reference states each endpoint's purpose and each parameter's effect, without when-not-to-use guidance (12). Parameter tables give ranges and allowed values in prose (8). Example requests and responses on each page, and status-code pages per API (12). Versions in the path (v1, v2, v4, v5) but no changelog (5).

NextBillion.ai 73

No OpenAPI document for the REST APIs was found in llms.txt or the docs. The hosted MCP server's 27 tools are defined with Zod schemas, so they carry typed JSON Schema inputs (15 of 25). llms.txt, llms-full.txt and a Markdown file for each docs page (10). Endpoint pages explain each parameter, and MCP tool descriptions say when not to use a tool, such as the geometry tools being straight-line rather than road distance (16). Parameter tables give types, allowed values and defaults, such as types and limit (default 10), though in packs several filters into one string (12). curl examples and a per-endpoint error table with causes (13). The MCP server has a dated changelog. No API changelog or versioned path was found (7). 15+10+16+12+13+7 = 73.

Reliability NextBillion.ai +22

MapQuest 23

Graded as a hosted service. No status page is linked from the developer site, the docs or the plans page (0). With no page there is no readable incident history (5). The reference marks endpoints 'Rate Limited Yes' and gives functional maximums (100 locations a batch, 50 a route, 25 a matrix) but no request-rate numbers (5). No 429, Retry-After or backoff guidance found (0). The Enterprise plan lists a service-level agreement, with no text published (3). The REST API is generally available and the MCP page calls the server production-ready (10).

NextBillion.ai 45

Hosted lines, for the REST APIs at api.nextbillion.io and the hosted MCP server. A status page at status.nextbillion.io, 'NextBillion.AI API Status', renders only in a browser, and its Statuspage-style JSON paths return 404, so we couldn't see its components (10) or read any history. That's our limit, not a finding, and the rubric gives 5 (5). The API reference states 2,400 queries a minute, or 40 a second, for continuous requests (15). Each endpoint's error table lists 429 as 'QPM or API request count quota reached', with no Retry-After or backoff guidance (5). No SLA found; the terms say access isn't warranted to be uninterrupted (0). The REST APIs are GA. The MCP server is at version 0.5.3 (10). 10+5+15+5+0+10 = 45.

Security & auth NextBillion.ai +18

MapQuest 28

REST uses API keys, several per account, created in the dashboard or by API. The MCP server uses OAuth with one scope, mcp:tools. That earns 20, less 10 because the key query parameter is the documented way to send the secret (10). No key scopes, referrer or IP restrictions, or read-only mode found in the docs (3). Place and address text is returned with no prompt-injection guidance (7). The usage endpoint reports transactions by key, service and hour (8). No security.txt, disclosure policy, bug bounty or certification found (0).

NextBillion.ai 46

The REST APIs take a single key query parameter, so a plain key that travels in URLs, which earns 20 less 10. The MCP server adds OAuth 2.1 with PKCE, seals the key into tokens with AES-256-GCM, accepts a Bearer header and stores nothing server-side, so 5 back (15). Every tool is read-only, and keys can carry an IP allowlist (12). Places results are POI and address text with no prompt-injection guidance (7). Usage alerts at 50, 75 and 90 per cent of credits, per the pricing FAQ. No per-call log found (5). /.well-known/security.txt returns 404, and we found no disclosure policy or bug bounty. The about page says the company follows ISO 27001 standards, without naming a certificate (7). 15+12+7+5+7 = 46.

Agent ergonomics NextBillion.ai +17

MapQuest 60

The MCP page names 13 tools. Their definitions were not read, so context cost is scored from the count and from REST controls such as maxResults, thumbMaps=false and outFormat (15). Place search pages with pageSize 1 to 50 and filters by category, circle, bounding box or corridor (16). Status codes are documented, with geocoding and directions errors carried in the response body and problem+json on the Account API (12). Most calls read and are safe to retry. Data Manager writes have no idempotency key, and MCP annotations were not read (10). Geocoding needs only key and location. The only current SDKs are browser libraries (7).

NextBillion.ai 77

MCP reading, since the hosted server is the agent surface. 27 tools, four of them for documentation and seven local geometry tools, with shapes simplified to a 500-vertex budget to save context (18). limit, types, country, bbox and circle filters, and batch geocoding of up to 100 queries (16). The error table explains each code, and the MCP masks the key in error text (15). Every API tool is marked readOnlyHint, idempotentHint and not destructive in the source (18). Few required parameters and explicit latitude and longitude objects, but no official server-side SDK, only mobile and web map SDKs (10). 18+16+15+18+10 = 77.

How the scores have moved

Verdicts

MapQuest

One account reaches geocoding, routing, place search and traffic through a REST API or a hosted MCP server with OAuth, at a published $0.0045 a transaction. No API terms, status page, changelog or product OpenAPI spec was found, and REST keys travel in the query string.

NextBillion.ai

NextBillion.ai covers routing, distance matrices, route optimisation, geocoding and places, and runs a hosted MCP server with 27 read-only annotated tools and OAuth sign-in. Pricing is by quote on annual licences, the REST API key travels in the query string, and no OpenAPI spec, API changelog or readable status history was found.

Before you call either

MapQuest

  1. Register an account and create an API key before connecting the MCP server. Every tool needs an active key, chosen by nickname on first use
  2. Send REST calls to https://www.mapquestapi.com with key in the query string, and redact it from logged URLs
  3. Read info.statuscode in geocoding and directions responses. 0 is success, and errors such as 610 (ambiguous location) arrive in the body
  4. Set thumbMaps=false and maxResults on geocoding, and pageSize (1 to 50) on place search, to keep responses small
  5. Do not store or cache geocodes on a monthly or pay-as-you-go plan

NextBillion.ai

  1. Connect through https://mcp.nextbillion.io so the key stays in a Bearer header or OAuth token rather than in request URLs
  2. Use the geometry tools only for straight-line questions; use directions or distance_matrix for travel time
  3. Batch up to 100 geocodes with geocode_batch instead of one call per address
  4. On 429 the quota or the 2,400-a-minute limit is reached; slow down and tell the user if credits are spent
  5. Search the docs with the MCP documentation tools before guessing a parameter
