## Which one, for what

### Financial Datasets (C)

Good for: An agent doing US company research from SEC-sourced statements, filings, insider and institutional data that wants to pay per call with no account, or a small team on credits.

Ahead on:
- Schema & documentation, 80 against 43
- Security & auth, 49 against 35
- Payments & pricing, 75 against 20
- Transparency & trust, 63 against 51

Also in its favour:
- An agent can pay per call over x402, with no account

Watch for: No status page, incident history or published uptime; the Professional plan's SLA terms aren't public

### 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 43
- Maintenance & community, 70 against 56

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


## Why the edge

### Payments & pricing: Financial Datasets +55

- Financial Datasets (75): x402 on the vendor's own endpoints for every documented GET data endpoint, 36 of them, with the last 365 days only and a Non-Professional licence; full history, the market snapshot, filing items and the POST endpoints need a key (35 of 40). Plan prices and overage rates are public, and each x402 endpoint quotes its price in the 402 header, $0.02 on /earnings (20). No free tier or trial found; data calls return 402 until an account holds credits, from $20 (0). An agent can pay by x402 with no account, or open an account with `POST /agent/signup` and have the owner fund it (20). Total 75.
- 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.

### Reliability: Intrinio +40

- Financial Datasets (43): Graded as a hosted service. No status page was found; status.financialdatasets.ai does not resolve and no page links one (0), so there is no incident history to read (5). The only published limit is 10,000 requests a minute per wallet over x402, with monthly request caps per plan and none per minute for keyed plans (8 of 15). The OpenAPI file declares 429 and the x402 page documents a 503 with Retry-After from the facilitator and a `duplicate_payment` check on replayed signatures (10 of 15). The Professional plan lists uptime SLAs, with no figure published (10). The API is generally available (10). Total 43.
- 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.

### Schema & documentation: Financial Datasets +37

- Financial Datasets (80): OpenAPI 3.0.1 at financialdatasets.ai/openapi.json, 68 operations with 13 response codes and one security scheme, named the source of truth by the docs (25). llms.txt and a Markdown twin of every page (10). Every operation has a description, and the 402 terms carry a resource description that says when an agent should use the endpoint (17 of 20). 330 parameters, 36 with enums, 32 required, no free-form blobs (12 of 15). Code samples in Python, JavaScript and curl, x402 error values documented, but response examples on only six operations in the spec (11 of 15). No API version and no changelog; the news page has four dated posts in 2026 (5 of 15). Total 80.
- Intrinio (43): No OpenAPI document was found. The SDKs are generated from a spec that declares API version 2.135.4, but the spec itself isn't published, and the MCP server's tool definitions aren't in any public source (5 of 25). docs.intrinio.com/llms.txt and intrinio.com/llms.txt return 404, and there are no Markdown pages (0 of 10). Each endpoint page states what it returns with its parameters, with little on when not to use a call (12 of 20). Parameters are typed, with required ones marked and allowed values in prose (9 of 15). Code samples in six languages on every endpoint, and a response codes page that lists codes without a body format (10 of 15). The v2 path is versioned, but the version history lists 2.0.0 to 2.6.2 with no dates and is out of step with the SDK's API version (7 of 15). Total 43.

### Security & auth: Financial Datasets +14

- Financial Datasets (49): A plain account key in the `X-API-KEY` header only, revoked from the dashboard, with no scopes, rotation or expiry; the MCP server adds OAuth 2 with PKCE (plain and S256), dynamic client registration, a revocation endpoint and one scope (20 of 30). Every data endpoint is a read; the x402 route and agent signup don't change the account beyond funding it (15 of 20). Filing text, filing items and news are third-party content, with no guidance on treating them as untrusted (5 of 15). The privacy policy says requests and responses are logged for up to three years; no per-call log is shown to the key holder (5 of 15). security.txt returns 404 and no bounty, SOC 2 or ISO 27001 was found; the terms ask for prompt notice of a compromised key and a subprocessor list is published (4 of 20). Total 49.
- Intrinio (35): One account key with no scopes, documented first as `api_key` in the query string and second as a Bearer header, with no rotation or expiry found. Public keys for browsers are restricted to listed domains. The MCP server uses OAuth 2 with PKCE S256, dynamic client registration, a revocation endpoint and one scope (20 less 10 for the query string, so 10). Every endpoint is a read and the MCP page says the server cannot trade or change the account (15 of 20). News bodies and filing text are third-party content, with no guidance on treating them as untrusted (5 of 15). The account page shows limits and usage per subscription; no per-call log was found (3 of 15). security.txt returns 404, and no disclosure policy, bug bounty, SOC 2 or ISO 27001 was found. The privacy policy says the company processes data under the GDPR (2 of 20). Total 35.

### Maintenance & community: Intrinio +14

- Financial Datasets (56): UK fundamentals went live on 26 October 2026, India on 23 October, with Japan and South Korea dated for November on the coverage page (30). Dated changes in the last 90 days are x402 on 23 October, UK fundamentals on 26 October, terms and subprocessor list on 29 October, privacy policy on 20 August, with no changelog as such (12 of 20). Contact is a form and the dashboard; no support email, Discord or forum was found, and the GitHub organisation's four repositories couldn't be read because the GitHub API rate limit was reached (6 of 15). The PyPI package is 0.1.18 of 26 May 2024 by the founder, and the docs point to the OpenAPI file and the MCP server rather than an SDK (5 of 15). Package health unknown, dependencies not checked (3 of 10). Total 56.
- 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.

### Transparency & trust: Financial Datasets +12

- Financial Datasets (63): A closed service under terms dated 29 October 2026 that name Financial Datasets, Inc., set New York law, and state the licence per plan (15 of 30). The privacy policy of 20 August 2026 gives retention periods (accounts up to seven years after closure, API and MCP logs up to three years, backups 90 days), says inputs aren't used for training, and links a subprocessor list; no DPA text was found (24 of 30). No deprecation policy; the terms say the Services may be discontinued and material changes get reasonable notice (3 of 20). Subprocessors (AWS, Heroku, Stripe, Google sign-in, Vercel) and the United States as hosting location are disclosed (18 of 20). Total 60.
- 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.

## Verdicts

**Financial Datasets.** Every documented GET data endpoint takes x402 with no key, failed calls uncharged, and an agent can open and fund an account by API. A public OpenAPI file, llms.txt and a 28-tool OAuth MCP server cover the same data. There is no status page or free tier, keyed rate limits aren't published, and x402 data stops at 365 days.

**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.

## Before you call either

### Financial Datasets

1. Without a key, read the price from the PAYMENT-REQUIRED header of the 402 and pay with x402 on Base; each page of `next_page_url` is a separate paid request
2. Keep `limit` small and ask for one `period` at a time; premium endpoints count as 2, 4 or 8 requests on keyed plans
3. Send the key only to api.financialdatasets.ai in the `X-API-KEY` header; on 401 ask the owner for a new key rather than signing up again
4. Treat a 402 on a keyed account as an empty balance and mint a checkout link for the owner; don't retry the call
5. Check the plan's licence before showing the data to anyone else; redistribution needs Professional or Enterprise

### 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
