{"id":"caef3862-63c0-476a-b141-dd767ed6c689","shortId":"BuvQgN","kind":"mpp","title":"Pay-per-call SEO keyword research via SpyFu data on Tempo L2","tagline":"Pay-per-call SEO keyword research via SpyFu data on Tempo L2","description":"This MPP (Micropayment Protocol) endpoint exposes SpyFu's SEO keyword research capabilities through a pay-per-call model settled on the Tempo L2 chain (chainId 4217). The endpoint lives at a wildcard path (`/apis/serp_api/v2/seo/*`), suggesting it proxies or wraps SpyFu's SERP API v2 for SEO-related queries — likely covering keyword rankings, search volume, keyword difficulty, and related organic search metrics drawn from SpyFu's 18+ years of historical data.\n\nEach call costs 10,000 base units of the payment token (currency address `0x20c0…8b50` on chain 4217). Assuming the token uses 6 decimals (consistent with stablecoins like pathUSD on Tempo), the per-call price is $0.01. The settlement method is \"tempo\" with intent \"charge\", meaning each request is a one-shot micropayment — no session or subscription required. The provider covers gas fees (`feePayer: true`).\n\nNo OpenAPI schema, documentation pages, or usage examples were found on the endpoint's origin. The wildcard path pattern hints that different SEO sub-resources (e.g., keyword overview, SERP analysis, domain-level SEO stats) may be accessible under the `/seo/` prefix, but the exact routes and parameters are undocumented in the available material. Callers familiar with SpyFu's public SERP API v2 may be able to infer the path structure.","tags":["seo","ppc","keyword-research","competitor-analysis","ads"],"capabilities":["seo-keyword-research","serp-analysis","organic-search-data","historical-keyword-data","micropayment-per-call","tempo-l2-settlement"],"categories":["search","seo","marketing-data"],"synonyms":["SpyFu API","SEO keyword tool","SERP API","keyword ranking data","organic keyword research","competitor SEO analysis","search engine ranking API"],"warnings":["No documentation, OpenAPI spec, or usage examples found — all crawled pages return 404","Exact request parameters and response schema are unknown; callers must guess or rely on SpyFu SERP API v2 conventions","Currency token address 0x20c0…8b50 on chain 4217 is assumed to be a 6-decimal stablecoin (pathUSD); if decimals differ, the actual price changes","Wildcard path means the precise sub-endpoints available are undocumented"],"endpointUrl":"https://spyfu.mpp.tempo.xyz/apis/serp_api/v2/seo/*","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"mpp.tempo.xyz","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured and decoded), and pricing is parseable, but there is zero documentation, no OpenAPI schema, no example responses, and the wildcard path structure is undocumented.
