Cleartax
Cleartax (operating as Clear, clear.in) is an Indian fintech and financial-compliance automation platform that provides tax, GST, and e-invoicing software for individuals, tax professionals, and over 4,000 enterprises. Clear exposes a suite of developer APIs through its documentation portal at docs.cleartax.in, including the Clear Finance Cloud (CFC) ingestion APIs, the GST 2.0 / GSP filing API, the Max ITC input-tax-credit reconciliation API, the GLS API, the E-Invoicing and E-Waybill APIs (with government IRP/NIC-compatible endpoints and DSC signing), the Invoicing API, and KSA (Saudi Arabia) e-invoicing APIs. APIs authenticate with a client secret exchanged for an access token and run against production (api.clear.in) and sandbox (api-sandbox.clear.in) hosts.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Cleartax the way a machine reads it — 8 machine-readable artifacts across 5 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Cleartax scores 36.7/100 (thin), with a separate agent-readiness read of 24/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Cleartax
Each block below is one kind of artifact we hold for Cleartax. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 5
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Clear E-Invoicing & E-Waybill API
Generate, cancel, and retrieve GST e-invoices (IRN) and e-waybills, including government IRP/NIC-compatible endpoints, DSC PDF signing, and bulk operations.
Clear GST 2.0 API
ASP/GSP GST filing API for uploading documents and filing G1-G9 returns via Clear's GST Suvidha Provider integration.
Clear Finance Cloud (CFC) API
Document ingestion APIs for sale and purchase documents via file upload (pre-signed URL) with access-token authentication and ingestion-status tracking.
Clear Max ITC API
Input Tax Credit (ITC) reconciliation API: upload purchase documents, trigger the Max ITC workflow, and fetch reconciliation results.
Clear Invoicing API
Create sale and non-sale documents, download document PDFs, and retrieve document details for invoicing workflows.
Security Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
