A SpyFu API alternative your coding agent can call

SEO tool seogeoaeo.ai now exposes every one of its research checks as both an MCP tool and a REST endpoint, positioning itself as a developer-callable alternative to SpyFu's API, according to the vendor's published documentation. The service prices runs in credits — $29 a month for 2,000 credits, $69 for 5,000, $199 for 22,000 and $499 for 130,000 — with MCP and REST access included on every plan, and individual jobs costing between 5 credits for a Meta ad lookup and 85 credits for a keyword gap report. The comparison could not confirm SpyFu's API pricing because SpyFu's pricing page failed to load in October 2026, leaving developers unable to verify which SpyFu plans include API access or what it costs.

If you want competitor research inside your own scripts or a coding agent, a SpyFu API alternative needs three things: an endpoint you can call without a sales call, a price you can predict per request, and output an agent can read. seogeoaeo.ai ships all three on every plan, through both MCP and REST. This comparison looks at it next to SpyFu's API from a developer's point of view, using only what each vendor publishes. What SpyFu says about its API SpyFu's home page has a section called "Build with the SpyFu API", which describes fast, documented endpoints to customize your stack and automate exports. SpyFu also offers SpyFu GPT, which brings its data into ChatGPT. We could not load SpyFu's pricing page in October 2026, so we cannot tell you which plans include the API or what it costs. Check spyfu.com before you plan a build around it. What seogeoaeo.ai exposes seogeoaeo.ai treats each check as a tool with a slug. The same slug is the MCP tool name and the REST path segment. - MCP: https://seogeoaeo.ai/api/mcp , Streamable HTTP, stateless, POST only. Send a bearer API key. - REST: POST /api/v1/tools/{slug}/runs with { "input": {...} } . - Keys: created at seogeoaeo.ai/api-keys, prefixed sga , shown once, spending the workspace's credits. A competitor ads lookup from the shell: curl -X POST https://seogeoaeo.ai/api/v1/tools/competitor-google-ads/runs \ -H "Authorization: Bearer $SEOGEOAEO API KEY" \ -H "Content-Type: application/json" \ -d '{"input":{"url":"https://www.example.com","market":"all"}}' The SpyFu jobs, as API calls | Job | Slug | Credits | Key inputs | |---|---|---|---| | A rival's Google ads | competitor-google-ads | 15 | url , market or all | | A rival's organic keywords | competitor-keywords | 35 | url , market | | Keywords they rank for that you do not | keyword-gap | 85 | url , competitor , market | | Who competes with you in Google | competitor-finder | 38 | url , market | | Keyword volume and CPC, up to 100 per run | keyword-metrics | 33 | keywords newline list , market | | A site's size: keywords, visits, links | domain-overview | 50 | url , market | | Active Facebook and Instagram ads | meta-ad-finder | 5 | query , mode | | A company's LinkedIn ads | linkedin-ad-finder | 5 | company | Markets are 20 country codes, from us , gb and de to br , jp and ae . The details that matter in a pipeline Cost caps. Every call accepts maxCredits . If the run would cost more, it is refused with a 402 max credits exceeded instead of charging you. Useful when an agent decides which tools to call. Safe retries. Pass an idempotencyKey and a retry after a timeout does not charge twice. Refunds on failure. A run that ends in a 502 tool failed or 503 unavailable gets its credits back. Readable output. Each successful run returns findings plus improvementTips : a status, a plain-text summary, a prioritized tip list and a verify step. An agent can act on the tips without parsing a dashboard export. Balance checks. GET /credits or the free check-credits MCP tool tells a script whether it can afford the next batch. Rate limits. A 429 comes with a Retry-After header, so backoff is easy to write. Predictable errors. Every error comes back as { "error": { "code", "message" } } . The codes are short and stable: invalid request , unauthorized , insufficient credits , not found , run in progress and the rest, so a client can branch on the code instead of parsing text. A tool that has been merged into another returns the new slug in replacement , which keeps old scripts from silently breaking. Pricing you can put in a spreadsheet Plans are $29 a month for 2,000 credits, $69 for 5,000, $199 for 22,000 and $499 for 130,000. API runs cost the same as runs in the browser, and MCP and REST come with every plan. A nightly job that pulls Google ads for five competitors costs 75 credits a night, about 2,250 a month, which fits the $69 plan. A weekly keyword gap against two rivals is 170 credits a week.
