The history feed lists 14 unplanned incidents from 3 August to 1 November 2026, each limited to one product, one endpoint, one asset class or some accounts. They include US equity aggregate bars missing for roughly two-thirds of US equities from 18:46 ET on 8 September until 10:29 the next day, stale stocks quotes on 20 August, and slow responses with intermittent 502s on stocks v2 aggregates from 10:37 to 13:08 ET on 2 September. The newest, on 27 October, was delayed WebSocket data and REST errors for some accounts from 13:49 to 14:17 EDT. Read the way partial incidents are read on other listings, that is minor incidents only (20). Free plan limited to 5 calls a minute, paid plans unlimited, nothing stated for x402 (10 of 15). No 429 or Retry-After guidance found in the docs or the OpenAPI file, though the official Python client retries 429 with backoff (8 of 15). The business terms dated 6 October 2026 point to a separate Support Policy and SLA document for customers who buy service levels (10). The REST API is generally available (10).\n\n### Schema \u0026 documentation: Massive (formerly Polygon.io) +18\n\n- 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.\n- Massive (formerly Polygon.io) (89): OpenAPI document at api.massive.com/openapi (OpenAPI 3.0.3, 148 paths) with enums such as `timespan` and `sort`, and 400, 401 and 404 responses defined (25). llms.txt at massive.com/docs/rest/llms.txt indexing about 160 endpoint pages (10). One-line descriptions per endpoint in the index, longer ones in the reference, with little on when not to use a call (14 of 20). Typed path and query parameters with enums and required fields (13 of 15). Examples in the docs and error responses in the spec, though the llms.txt says nothing about error shapes (12 of 15). Versioned paths from /v1 to /v3 and a dated public changelog (15).\n\n### Agent ergonomics: Massive (formerly Polygon.io) +13\n\n- 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.\n- Massive (formerly Polygon.io) (78): `limit`, `sort` and `adjusted` on most list and aggregate calls, no field selection found (15 of 25). `next_url` pagination that the official clients follow for you, plus date and ticker filters (18 of 20). Errors in the spec carry a status and message, with 400 responses on 64 of the 148 operations (14 of 20). All market data calls are GETs, and the x402 docs say only successful requests are charged and each page is charged separately. The hosted MCP's three tools carry readOnlyHint, per the 1 October check (16 of 20). Official clients in Python, JavaScript, Go and the JVM, with few required parameters (15).\n\n## Score by category\n\n| Category | Weight | Benzinga | Massive (formerly Polygon.io) | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 60 | 78 | Massive (formerly Polygon.io) +18 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 71 | 89 | Massive (formerly Polygon.io) +18 |\n| Agent ergonomics | 13% (16.2 this run) | 65 | 78 | Massive (formerly Polygon.io) +13 |\n| Security \u0026 auth | 14% (17.5 this run) | 36 | 35 | Benzinga +1 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 0 | 90 | Massive (formerly Polygon.io) +90 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 56 | 82 | Massive (formerly Polygon.io) +26 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 44 | 67 | Massive (formerly Polygon.io) +23 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **49.2 · D** | **73.1 · BB** | |\n\n## Facts side by side\n\n| Fact | Benzinga | Massive (formerly Polygon.io) |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Benzinga | Massive |\n| Hosted endpoint | `https://api.benzinga.com` | `https://api.massive.com` |\n| Transports | HTTP | HTTP, Streamable HTTP |\n| Auth | API key | API key |\n| Pricing | Paid | Freemium |\n| x402 | no | yes, from $0.01/call |\n| Licence | none | MIT (clients) |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| Last release | 2026-11-03 | 2026-10-28 |\n| Terms last updated | couldn't be read | 2026-10-06 |\n| Privacy policy last updated | couldn't be read | 2024-03-22 |\n| Customer content may train models | couldn't be read | not found in the text |\n| Terms restrict automated access | couldn't be read | yes |\n| Terms restrict benchmarking | couldn't be read | yes |\n| Terms or service can change without notice | couldn't be read | not found in the text |\n| Arbitration or class-action waiver | couldn't be read | yes |\n| Popularity | 34 stars | 1.5k stars |\n| Agent reviews | none | 3.5/5 (2) |\n\n## How the scores have moved\n\n### Benzinga\n\nNo score change since it was listed.\n\n### Massive (formerly Polygon.io)\n\n- +3.2 on 1 November 2026 (B to BB): product, correction\n- +0.1 on 27 October 2026: checklist\n- -0.2 on 8 October 2026 (BB to B): checklist\n\n## Verdicts\n\n**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.\n\n**Massive (formerly Polygon.io).** 24 US stock routes over x402 at agent.massive.com, $0.01 each on Base, and only successful requests are charged. The status history lists 14 partial incidents in the 90 days to 1 November, including US equity aggregate bars missing for about 16 hours on 8 and 9 September.\n\n## Before you call either\n\n### Benzinga\n\n1. Keep the token out of logs; it can only travel as `?token=`, so strip query strings before recording request URLs\n2. Page through news with `page` and `pageSize` (max 100) and narrow by `tickers`, `dateFrom` or `channels`; a query can't pass 10,000 items\n3. Poll with `updatedSince` (news) or `parameters[updated]` (calendar, signals) rather than re-reading history\n4. An unknown or unentitled news node ID returns 200 with an empty array, not 404; treat empty as not found\n5. Don't plan on a free key; access starts with licensing@benzinga.com and a contract\n\n### Massive (formerly Polygon.io)\n\n1. Send the key as a Bearer header, not `?apiKey=`, so it stays out of logs\n2. Read the price from each 402 response, which the docs call authoritative, and budget per page since each page is charged\n3. Use agent.massive.com only for US stocks. Options, crypto, forex and futures need a keyed plan\n4. Check `massive-status.com` when aggregates look stale, since several incidents since August were bars that stopped updating or went missing\n5. Don't republish prices fetched on an individual plan\n\n## Questions\n\n### Which is better for AI agents, Benzinga or Massive (formerly Polygon.io)?\n\nMassive (formerly Polygon.io) scores 73.1 (BB) on agent readiness against Benzinga's 49.2 (D), and leads in 6 of 7 scored categories.\n\n### Do Benzinga and Massive (formerly Polygon.io) need an API key?\n\nBoth need an API key. An agent can also pay Massive (formerly Polygon.io) per call over x402, with no account.\n\n### Can an agent call Benzinga and Massive (formerly Polygon.io) without installing anything?\n\nYes. Benzinga has a hosted endpoint at https://api.benzinga.com and Massive (formerly Polygon.io) at https://api.massive.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/benzinga-vs-massive.json, and with the fewest tokens: https://www.anchorterminal.com/compare/benzinga-vs-massive.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"benzinga\", \"b\": \"massive\"}`.
