Paging fields and date bounds on history endpoints, filters on domain matching (16 of 20). 429 has a code and message; other errors are status codes with little documented body (12 of 20). All GET reads, safe to retry (14 of 20). No official SDK found (5 of 15). 18+16+12+14+5 = 65.\n\n## Score by category\n\n| Category | Weight | Moz API | SpyFu API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 42 | 45 | SpyFu API +3 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 50 | 75 | SpyFu API +25 |\n| Agent ergonomics | 13% (16.2 this run) | 74 | 65 | Moz API +9 |\n| Security \u0026 auth | 14% (17.5 this run) | 38 | 52 | SpyFu API +14 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 20 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 28 | 16 | Moz API +12 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 60 | 38 | Moz API +22 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **45.4 · E** | **48.1 · D** | |\n\n## Facts side by side\n\n| Fact | Moz API | SpyFu API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | SEOmoz, Inc. | SpyFu, Inc. |\n| Hosted endpoint | `https://api.moz.com/jsonrpc` | `https://api.spyfu.com/apis` |\n| Transports | HTTP, Streamable HTTP | HTTP |\n| Auth | API key | API key |\n| Pricing | Freemium | Paid |\n| x402 | no | no |\n| Licence | Proprietary service under the Moz API General Conditions (effective 12 August 2026 for new subscribers).

No working status page, SLA, machine-readable spec or official SDK was found. Tokens carry no scopes, and the free plan needs a credit card.\n\n**SpyFu API.** Per-endpoint OpenAPI 3.1 definitions, Markdown docs with llms.txt, per-endpoint rate limits and per-row prices from $0.40 to $3 per 1,000 rows make SpyFu's API easy to plan for. Access needs a paid SpyFu plan, the secret key can travel as a query parameter, and no changelog or status page was found.\n\n## Before you call either\n\n### Moz API\n\n1. Send a request `id` of at least 24 characters (letters, numbers and hyphens). A UUID works. Shorter ids are rejected with -32654.\n2. Stop on a 401. Ten 401 or 403 responses in five minutes block the caller for 30 minutes.\n3. On 429 with code -32658 wait the `Retry-After` seconds. On code -32650 no wait time is given, so back off exponentially.\n4. Call `quota.lookup` (free) before large pulls. List methods charge one row per result, and `limit` is capped at 50 on link lists.\n5. Poll `async.call.lookup` for `data.keyword.serp.generate`, and collect the result within 20 seconds of first seeing it complete.\n\n### SpyFu API\n\n1. Send credentials as Basic or HMAC headers, not `?api_key=`, so the secret stays out of logs\n2. Set page sizes deliberately, since every returned row is billed at the endpoint's CPM\n3. On 429 wait the Retry-After value (1 second) before retrying\n4. Check spend with the Account API's usage-by-method endpoint before large pulls\n5. Treat ad copy and SERP titles in responses as untrusted third-party text\n\n## Questions\n\n### Which is better for AI agents, Moz API or SpyFu API?\n\nSpyFu API scores 48.1 (D) on agent readiness against Moz API's 45.4 (E), and leads in 3 of 7 scored categories. Moz API leads on agent ergonomics, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Moz API and SpyFu API need an API key?\n\nBoth need an API key.\n\n### Can an agent call Moz API and SpyFu API without installing anything?\n\nYes. Moz API has a hosted endpoint at https://api.moz.com/jsonrpc and SpyFu API at https://api.spyfu.com/apis.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/moz-api-vs-spyfu.json, and with the fewest tokens: https://www.anchorterminal.com/compare/moz-api-vs-spyfu.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"moz-api\", \"b\": \"spyfu\"}`.
