Argorant for Codex

Let Codex write your lead-gen stack on a verified data API.

Codex is at its best turning a spec into working code. Argorant gives it a spec-friendly target: a REST API that mirrors the product one call at a time, an OpenAPI description it can read, and an MCP server it can call directly while it develops. 'Build me a script that pulls verified CTOs at fintech startups into our CRM' becomes an afternoon, not a sprint.

Setup

Connect Codex to Argorant

Two ways in, and Codex can use both at once:

Create an Argorant account and grab credentials from the dashboard.

Hand Codex the API reference at argorant.com/docs — search, count, reveal, and export are plain REST endpoints.

Optionally add https://mcp.argorant.com/mcp as an MCP server so Codex can test calls live while it writes the integration.

Review the generated code, run it, and watch verified contacts land in your stack.

API integration with Codex

An API that reads like the product, so the agent gets it right.

Codex writes correct integrations when the API is predictable. Argorant's endpoints return the same numbers you see in the app: search and count for free exploration, reveal for metered contact data, export for a verified, time-boxed download link. No surprise pagination schemes, no undocumented states for the agent to hallucinate around.

Lead-gen automation with Codex

From one-off list pulls to a pipeline that runs itself.

Start with a script that pulls a segment; let Codex grow it into a scheduled job that tops up your CRM weekly, skips contacts you already have, and only ever exports verified addresses. Because verification happens at export time, the automation stays trustworthy even months after the code was written.

Live development over MCP

Codex can call the database while it codes against it.

Add the MCP server and Codex doesn't have to guess what a response looks like — it resolves a real industry, runs a real count, inspects a real payload, then writes code that matches reality. Tests against live shapes, not stale fixtures copied from docs.

How many VP Sales contacts can we reach at SaaS companies in Germany?

→ suggest_industry·count_matches

8,412 VP-of-Sales contacts at software companies in Germany.

6,930 already verified · the rest verify live at export. Want me to prepare the list for your workspace owner to reveal?

Event-driven plumbing

Webhooks Codex can build on, signed and retried.

Ask Codex to wire the receiving end: Argorant signs every webhook payload and retries on failure, so the export-finished handler it writes is a few honest lines, not a defensive poll loop. Verification batches, export completion, and credit alerts all arrive as events.

Testimonials

Revenue teams that stopped tolerating bounces.

“We replaced ZoomInfo in a weekend. Same coverage, a fraction of the cost, and the emails actually land. Our bounce rate went from 28% to under 3%.”

Maria Chen

VP Sales · 30-rep outbound team at a logistics SaaS

“Verification at export is the whole game. Every list we pull is checked live before it hits our sequencer — no more scrubbing through a second tool.”

James Okafor

Founder · seed-stage developer-tools startup

“We were paying $40K a year on an annual contract for data that bounced. Argorant is self-serve, a fraction of that spend, and the deliverability is night and day.”

Yes — the REST API is documented at argorant.com/docs with an OpenAPI description, and the endpoints map one-to-one to product actions (search, count, reveal, export). That predictability is exactly what coding agents need to produce correct code on the first pass.

Both. Use MCP while developing so the agent can make live calls and see real response shapes, then ship the integration on the REST API with a scoped credential.

Searches and counts are free; reveals and exports draw down workspace credits. A well-built automation counts first, exports only the segment it needs, and you can subscribe to a low-credit webhook so the pipeline alerts before it stalls.

Contacts are continuously re-verified and every export runs a final deliverability pass at download time, so a pipeline written once keeps delivering current addresses.
