## Which one, for what

### Alpha Vantage (E)

Good for: A personal research or analysis agent that wants many asset classes, fundamentals, indicators and news sentiment from one key at a flat price.

Ahead on:
- Payments & pricing, 30 against 0
- Maintenance & community, 63 against 56
- Transparency & trust, 50 against 44

Also in its favour:
- Runs on your own machine

Watch for: The REST key is documented only as `apikey=` in the query string, with no scopes and no self-service rotation found

### Benzinga (D)

Good for: A licensed firm's agent that needs Benzinga's own newswire, calendars, analyst ratings and transcripts as structured data with deltas.

Ahead on:
- Reliability, 60 against 30
- Schema & documentation, 71 against 46
- Agent ergonomics, 65 against 54

Watch for: The API token is sent only as the `token` query parameter, with no header option, scopes or rotation found


## Why the edge

### Reliability: Benzinga +30

- Alpha Vantage (30): Graded as a hosted service. No status page was found. The site links none and status.alphavantage.co has no valid certificate (0). With no page there is no incident history to read (5). Limits are published with numbers, 25 requests a day on a free key and 75 to 1,200 a minute on premium plans (15). No 429, Retry-After or backoff guidance was found, and in our test calls a missing key and an unknown function both returned HTTP 200 with a text field (0). No SLA was found, and the terms supply the service as is (0). The REST API is generally available (10). Total 30.
- Benzinga (60): Graded as a hosted service. Atlassian Statuspage at benzinga1.statuspage.io with seven API components (20). The incident feed holds 14 incidents, the newest on 14 September 2023, so the 90 days to 3 November 2026 are clean (30). No rate limit numbers are published; the FAQ says limits depend on the API and the subscription tier (0 of 15). No 429, Retry-After or backoff guidance was found in the docs or the specs (0 of 15). No SLA was found; the architecture page cites a 99.9 per cent availability figure as a claim, and the terms were unread (0). The APIs are generally available (10). Total 60.

### Payments & pricing: Alpha Vantage +30

- Alpha Vantage (30): No x402, MPP or L402 (0). Five monthly plans are public with prices, sold by requests a minute and not by call (10). A free key gives 25 requests a day with no card (20). The key comes from a browser form that asks for a name and an email address, and no key API was found (0). Total 30.
- Benzinga (0): No x402, MPP or L402 (0). No prices are published anywhere we could read; the docs say to email or call licensing and the APIs page on www.benzinga.com answered 403 (0). The FAQ says a trial or sandbox is often available, with no terms, length or card condition, and the registration page was unread (0). A person registers in a browser or by email (0). Total 0, with pricing and registration recorded as unchecked.

### Schema & documentation: Benzinga +25

- Alpha Vantage (46): The surface graded is the REST API, with the official MCP server noted. No OpenAPI document was found for the API. The MCP server's tools carry typed inputs generated from Python signatures (10 of 25). `/llms.txt` returns 404, and the only Markdown is the MCP README (3 of 10). Each function has a purpose statement, a parameter list and a premium marker, with little on when not to use it (13 of 20). Required and optional parameters are marked and allowed values listed in prose, while MCP inputs such as `interval` are plain strings with no enums (8 of 15). Every function has demo URLs and code in four languages, but no error responses are documented (8 of 15). The API has no version and no changelog. The MCP repository's changelog stops at 0.3.2 on 27 February 2026 with later changes under Unreleased (4 of 15). Total 46.
- Benzinga (71): The docs are generated from 11 OpenAPI 3 specs in the public Benzinga/benzinga-docs repository, 80 operations, and the raw YAML is linked from the welcome page (25). llms.txt and a Markdown twin of every page (10). Operations carry a summary and a sentence or two on scope, with little on when not to use a call (12 of 20). Typed query parameters with enums on the calendar (50) and news (9) specs, and the token as a query parameter (10 of 15). Examples on most operations, but the error responses in the specs are thin, 400, 499 and 500 on news, with the 401 and 404 bodies shown only as examples (9 of 15). Versioned paths (/api/v2) and three changelog pages that are empty templates (5 of 15). Total 71.

### Agent ergonomics: Benzinga +11

- Alpha Vantage (54): `outputsize=compact` returns the latest 100 points, `datatype=csv` shortens long series, and the MCP server previews anything over 32,000 tokens with a link to the full data. No field selection (15 of 25). `limit` and time filters on news and a `month` parameter for intraday history, with no pagination elsewhere (10 of 20). Errors and limit notices arrive as HTTP 200 with free text under `Error Message` or `Information`, undocumented (5 of 20). Every call is a GET read, and all MCP tools carry readOnlyHint true and destructiveHint false (16 of 20). Few required parameters and sensible defaults. No official SDK, only a Python CLI and community libraries (8 of 15). Total 54.
- Benzinga (65): `displayOutput` of headline, abstract or full sizes a news response, and `pageSize` runs to 100 (18 of 25). `page` and `pageSize`, ticker, channel, date and `updatedSince` filters, with a 10,000-item cap per query that the docs explain how to work round (18 of 20). Error bodies carry a code, an id and a message in the examples, but an unknown node ID returns 200 with an empty array and the spec's response list doesn't match the examples (10 of 20). Every data call is a read, with no safe-retry guidance; the webhook API registers endpoints (12 of 20). Few required parameters, but the Python client is from 2021, the JavaScript client from 2023 and the docs' SDK page is template text (7 of 15). Total 65.

### Maintenance & community: Alpha Vantage +7

- Alpha Vantage (63): The MCP server repository, which a workflow deploys to the hosted server, had its last commit on 3 October 2026, and the site footer says it was updated in October 2026 (30). No tags, and the newest PyPI release is 17 March 2026, so there are no dated releases in the last 90 days, though the repository shows over 30 commits since 21 July (8 of 20). Pull requests 14 and 18 were merged within a day and issue 16 closed in a day, while issue 17, a reported startup crash, has been open since 4 September. Support is by email (10 of 25). The server sits in the official MCP registry under the vendor's GitHub namespace, with no official SDKs (12 of 15). The published package leaves its `mcp` dependency unpinned, and the workflows deploy and publish without a visible test run (3 of 10). Total 63.
- Benzinga (56): The docs repository had commits on 2 and 3 November 2026 moving OpenAPI specs from GitLab, and the robots.txt is versioned 11 September 2026 (30). Eight commit days between 23 October and 3 November 2026, all spec transfers, with no dated changelog entry anywhere (12 of 20). Support is licensing@benzinga.com, partners@benzinga.com and a phone line, with a status page; GitHub issue responsiveness was not read (6 of 15). The Python client's last PyPI release is 1.21 of 8 February 2021 and the JavaScript client was last pushed in July 2023, so no current official SDK (5 of 15). The Python client repository was pushed in March 2026 with no release; CI not checked (3 of 10). Total 56.

### Transparency & trust: Alpha Vantage +6

- Alpha Vantage (50): A closed service under short terms that are clear on scope, personal and non-commercial by default, with the MCP server under MIT (15 of 30). The privacy policy of 25 August 2025 describes the website, keeps personal data 'only for as long as is necessary' with no periods, and no DPA was found. It does not describe the request analytics visible in the MCP server source (8 of 30). No deprecation policy. The MCP README marks the key-in-URL connection deprecated with no date, and the changelog flags breaking changes (3 of 20). Google Analytics, Mixpanel, GitHub, GitLab, PayPal or Braintree and Stripe are named, and data is processed in the United States (10 of 20). Total 36.
- Benzinga (44): A closed service whose terms could not be read, since www.benzinga.com answered 403; the docs footer links them (8 of 30). The privacy policy was unread for the same reason, and the docs say nothing about retention (0 of 30, unchecked). No deprecation policy or dated notices; the changelog pages are empty (0 of 20). The architecture page says the platform runs on Amazon Web Services with Kong Gateway, with no subprocessor list or data location statement (5 of 20). Total 13.

### Benzinga

No score change since it was listed.

## Verdicts

**Alpha Vantage.** One GET endpoint covers about 130 documented functions, with a free key at 25 requests a day and an official MCP server whose tools are all marked read-only. The REST key travels only in the query string, errors come back as HTTP 200 with a text message, and no status page, SLA or OpenAPI document was found.

**Benzinga.** Benzinga's news, calendar and transcript APIs are documented from 11 public OpenAPI specs with an llms.txt and a Statuspage. The token travels in the query string, no prices or rate limit numbers are published, the Python client was last released in February 2021, and the vendor's main site refused our reader, so its terms and privacy policy are unread.

## Before you call either

### Alpha Vantage

1. Check every 200 response for `Error Message`, `Information` or `Note` keys before parsing data. The API does not signal failures or limits by status code
2. Budget 25 requests a day on a free key. Real-time, 15-minute delayed and intraday US data, index data and several indicators need a premium plan
3. Keep `outputsize=compact` unless full history is needed, and ask for `datatype=csv` on long series to cut tokens
4. Use the hosted MCP server with OAuth at `https://mcp.alphavantage.co/mcp`. The `?apikey=` MCP URL is marked deprecated
5. Confirm the owner's use is personal and non-commercial, or that a commercial agreement exists, before acting for a business

### Benzinga

1. Keep the token out of logs; it can only travel as `?token=`, so strip query strings before recording request URLs
2. Page through news with `page` and `pageSize` (max 100) and narrow by `tickers`, `dateFrom` or `channels`; a query can't pass 10,000 items
3. Poll with `updatedSince` (news) or `parameters[updated]` (calendar, signals) rather than re-reading history
4. An unknown or unentitled news node ID returns 200 with an empty array, not 404; treat empty as not found
5. Don't plan on a free key; access starts with licensing@benzinga.com and a contract
