## Which one, for what

### Intrinio (C)

Good for: An agent doing US equity, options and fundamentals research on a paid plan that wants one vendor for prices, filings, estimates and an OAuth MCP server.

Ahead on:
- Reliability, 83 against 60
- Agent ergonomics, 70 against 56
- Maintenance & community, 70 against 50

Watch for: The API key is documented as `api_key` in the query string as the first option, with no scopes, rotation or expiry found

### Tiingo (D)

Good for: Agents that need clean US end-of-day composites with dividend and split adjustments, fund fees and news on a cheap plan, and anyone who values a long changelog.

Ahead on:
- Payments & pricing, 30 against 20
- Transparency & trust, 57 against 51

Watch for: The connecting guide documents the token as `?token=` in the URL alongside the header


## Why the edge

### Reliability: Intrinio +23

- Intrinio (83): Graded as a hosted service. Atlassian Statuspage at status.intrinio.com with APIv2 and APIv1 components (20). The incident feed's newest entry is a delayed SIP feed for CTA on 24 June 2026, so the 90 days to 3 November are clean (30). Limits are published in part. Pages above 100 records and bulk requests are 1 a minute on free feeds and 1 a second on paid ones, free feeds are throttled at 100 requests a second, and the daily and per-minute caps for a plan are shown only on the account page (8 of 15). A 429 carries an explanation of the limit and a 503 marks throttling or the 25-second timeout, with no Retry-After or backoff guidance (5 of 15). The Enterprise plan lists an SLA (10). The REST API is generally available (10). Total 83.
- Tiingo (60): Read with the hosted lines. A public status page on Instatus at status.tiingo.com lists 13 components with a notice history (20). The history in the 90 days to 3 November 2026 shows a 9 hour 59 minute outage of the Blue Ocean ATS endpoints on 21 October, a WebSocket issue on 21 September and two maintenance windows, with nothing recorded before 21 September; a long outage of one niche feed rather than the core price API (15). Limits are published with numbers, 50 and 10,000 requests an hour, 1,000 and 100,000 a day and 1 GB and 40 GB a month (15). No 429, Retry-After or backoff guidance was found (0). No SLA found (0). The end-of-day, news, crypto and forex APIs are generally available, while Equity Realtime and BOATS are in beta (10). 20 + 15 + 15 + 0 + 0 + 10 = 60.

### Maintenance & community: Intrinio +20

- Intrinio (70): The six real-time websocket SDK repositories were pushed between 22 and 29 October 2026, and the MCP server is labelled New on the vendor's page (30). The last tagged release found is intrinio-sdk 7.2.0 on PyPI on 27 May 2026, following 7.0.0 on 2 March and 7.1.0 on 24 March; the October pushes have no tags or dated changelog entries, and the API version history carries no dates (10 of 20). Support is live chat through HubSpot, an AI chat and support@intrinio.com, with a status page; GitHub issue activity was not read (8 of 15). Official SDKs are current in six languages (15). The Python SDK is generated by swagger-codegen with CI not checked (7 of 10). Total 70.
- Tiingo (50): Read as a closed service. The changelog's newest entry is 9 October 2026 (30). Entries dated 9 October and 8 September 2026 fall in the last 90 days, with 21 July just outside, and the status page adds a maintenance window on 28 September (12 of 20). A dated changelog, a support address and a blog, with the developer programme promising priority email support (8 of 15). No official SDK (0 of 15). No package to assess (0 of 10). 30 + 12 + 8 + 0 + 0 = 50.

### Agent ergonomics: Intrinio +14

- Intrinio (70): `page_size` from 100 up to 10,000 sizes a response, and the MCP server batches ticker lists, but there is no field selection (15 of 25). `next_page` tokens, date and symbol filters on the data endpoints (18 of 20). Response codes are documented, 403 for an unsubscribed feed and 429 with a limit explanation, with no error body format or error code reference (10 of 20). Every call is a read and the vendor says the MCP server writes nothing back, but no readOnlyHint or safe-retry guidance was found (12 of 20). Few required parameters, and official SDKs in Python, C#, Java, JavaScript, R and Ruby (15). Total 70.
- Tiingo (56): `startDate`, `endDate`, `resampleFreq`, `format=csv` and column selection on some endpoints size responses; no field selection on end-of-day prices (15 of 25). Date ranges throughout and limit and offset on news, no cursor (15 of 20). Errors are undocumented; a missing token answered 403 with a JSON `detail` field in our one test call (3 of 20). Every call is a read (16 of 20). Few required parameters, but no official SDK; the docs point to third-party packages (7 of 15). 15 + 15 + 3 + 16 + 7 = 56.

### Payments & pricing: Tiingo +10

- Intrinio (20): No x402, MPP or L402 (0). Plan prices are public without a login, $150, $333 rising to $999, and $1,250 and up, with no per-call price (10). Both self-serve plans say a free trial is available, and the trial length and card requirement were not found on the pricing, plan or terms pages, since the plan pages are drawn by script (10 of 20). A person signs up in a browser; no key API was found (0). Total 20.
- Tiingo (30): No x402, MPP or L402 (0). Two plan prices public without login, $0 and $30 a month, sold by requests an hour and a day rather than per call; fundamentals and commercial licences by email (10). A free Starter plan at 1,000 requests a day with no card requirement stated (20). The token comes from a browser signup, and the developer programme forbids programmatic registration (0). 0 + 10 + 20 + 0 = 30.

### Transparency & trust: Tiingo +6

- Intrinio (51): A closed service under terms effective 3 September 2026 that are clear on personal, internal and commercial use and name Intrinio, Inc. (15 of 30). The privacy policy is dated 30 June 2018, names no retention periods, subprocessors or DPA, and says only that connection details may be retained; the terms require deletion within 30 days of termination with an officer's certification (8 of 30). No deprecation policy, and the version history has no dates (3 of 20). Data is processed in the United States; no subprocessor list (5 of 20). Total 31.
- Tiingo (57): A closed service whose terms sit on app.tiingo.com, which answered 403 to every request, so they were not read; the pricing and documentation pages define internal, commercial and redistribution licences (8 of 30). The privacy policy is on the same host and was not read (0 of 30). The developer programme commits to a year of continued support after a breaking change, with changes posted in the changelog and emailed to registered developers, and the changelog's 9 October 2026 entry describes a changed default for prevClose (16 of 20). Equinix hosting is named on the about page, with no processor list or data location (4 of 20). 8 + 0 + 16 + 4 = 28.

## Verdicts

**Intrinio.** A read-only US equities, options and fundamentals API with a clean status history, SDKs in six languages, paging up to 10,000 records and an OAuth MCP server included in every plan. The REST key is documented in the query string, no OpenAPI document or llms.txt was found, the version history is undated, and plans start at $150 a month.

**Tiingo.** A dated changelog since 2017, a one-year support commitment after breaking changes, an Instatus status page and a free token at 1,000 requests a day. The token is documented in the URL, no OpenAPI document, error reference, SDK or MCP server exists, and the terms and privacy policy sit on a host that refused our reader.

## Before you call either

### Intrinio

1. Send the key as `Authorization: Bearer`, not `?api_key=`, so it stays out of logs
2. Expect 403 for a data feed the account isn't subscribed to, 429 with an explanation when a limit is hit, and 503 when a request passes 25 seconds; shrink the query rather than retry at once
3. Keep `page_size` at 100 or below unless the plan is paid, since larger pages are limited to one request a minute on free feeds
4. Confirm the plan before displaying or passing Intrinio data to anyone else; the Individual plan forbids it
5. The MCP server returns a message naming the product that unlocks data outside the plan; don't retry the same call

### Tiingo

1. Send the token as `Authorization: Token <token>`, not as `?token=` in the URL
2. Ask for `format=csv` on large price pulls; the docs say CSV is 4 to 5 times faster than JSON, and bandwidth counts against the monthly cap
3. Count requests an hour and a day, not per second; 50 an hour on Starter, 10,000 on Power, reset on the hour and at midnight ET
4. Expect 403 `{"detail":"Please supply a token"}` without a token; other error shapes are undocumented, so log the body
5. Use dashes in share classes (BRK-A), and fetch supported_tickers.zip rather than guessing symbols
