Find contact data gaps
Contact completeness table with provenance. Give your connected LLM the build instructions to create this reusable tool.

- What you provide
- Up to five supplied business emails and the associated company domains.
- What you get
- Contact completeness table with provenance.
How your tool works.
Enrich person and company; count coverage against a supplied field list; report missing fields.
Your agent writes and saves the Python tool. Recurse supplies eligible API access and cloud execution. You can ask your agent to edit it and run it again.
The output.
Contact completeness table with provenance.
The APIs in your tool.
Use eligible APIs through your Recurse balance. You do not need to open a separate provider account or fund a separate wallet for these operations. Operations requiring your own connected account remain subject to availability.

0.2 credits, billed CONDITIONALLY — charged only when company name, category/description/tags, location or country code AND company size all come back. A 404 or a partial record is free. Still the cheapest companies.enrich in this catalog. OBSERVED 2026-07-31 — a call on a domain never queried on this key moved GET /account's requests.credits.used by exactly 0.200; the same call repeated on an already-queried domain moved it by 0.000 (cached, not free).
Price source · API documentation
These are dated API unit rates, not a whole-task quote. Your agent checks current availability and costs before execution. Settled provider costs pass through at 1×; preparation and execution compute are charged at 4×.
Build it with your agent.
Your agent asks for missing inputs and a total spending cap before chargeable work.
Read the full build instructions
Build and save a reusable Recurse tool called find_contact_data_gaps. Inputs: Up to five supplied business emails and the associated company domains. Execution logic: Enrich person and company; count coverage against a supplied field list; report missing fields. Output contract: Contact completeness table with provenance. Declared APIs: hunter.people.enrich, hunter.companies.enrich. Inspect these APIs' current executable status, native parameters, response examples and costs. Resolve and test response-field mappings before writing dependent steps; supplier response schemas in this research snapshot are incomplete. Do not silently substitute APIs. Implement the sequence, joins, filters and calculations in plain Python with from recurse_apis import call. Validate input and JSON output schemas in tools.yaml; lock dependencies in uv.lock. Keep interpretation outside the tool. Use at most 20 sequential API requests, 64 KiB inputs, 256 KiB results and 300 seconds. Limit fetched pages/posts and truncate evidence explicitly. Return null with a reason for missing fields; do not invent dates, contacts, prices or counts. Create success, empty, malformed-response and provider-error tests. Ask me for the missing inputs and one total spending cap before chargeable preparation. Build the standard source archive and perform Recurse's scoped HTTP upload; never send inline source to private_stage. Inspect the prepared function before private_call. Reuse prepared source for later invocations and retain its version ID. If this interface cannot build files and perform the upload, explain the missing capability and provide the source project for a capable interface. Return the receipt and structured result here. Do not publish, send messages or start ongoing monitoring.
Before you start.
Your interface needs file creation, source bundling and scoped HTTP upload as well as a Recurse connection.
Limits and validation
20 sequential API requests, 300 seconds, 64 KiB input and 256 KiB result per private run.
- A connected Recurse account and sufficient wallet funds are required.
- Authoring requires file creation, source bundling and scoped HTTP upload in addition to MCP.
- Public data may be incomplete, stale, unavailable or sample-limited.
- Recheck current API access, prices and response-field mappings before paid execution.
- A fresh invocation is required for a fresh observation; no background scheduler is included.
This specification was checked against API metadata; a ready-made implementation is not included. Live provider execution has not been tested.
