Email Lookup

post_waveinflu_email_lookup
Read-onlyIdempotent

Looks up the contact email for one Instagram, TikTok, or YouTube creator from a profile URL. Pass profile_url; the response returns the parsed platform, the normalized profile_url, and an email object {status, value}. A not_found status (with value null) is a normal result, not an error, and is still billed as one valid lookup. Handles one creator per call. To assemble a creator list first, use Similar Creators or AI Search — each match already includes an email for most creators; use this endpoint for the ones that come back null.

TDQS

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the read-only/idempotent safety profile, but the description adds genuinely non-structured behavior: not_found with null value is a normal result rather than an error, and it is still billed as one valid lookup. It also states the one-creator-per-call constraint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four tight sentences, front-loaded with the core action, then parameter/response, then the billing caveat, then the sibling routing. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter lookup with an output schema and full annotation coverage, the description supplies everything an agent needs: input, normal-vs-error semantics, billing implication, cardinality, and sibling routing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and there is a single required parameter, so the schema already documents profile_url fully. The description only says 'Pass profile_url' and otherwise spends its words on output shape, adding little meaning beyond the schema. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (looks up), resource (contact email), scope (one creator), and the supported platforms (Instagram, TikTok, YouTube). An agent can distinguish this from the batch/search siblings without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent: assemble a creator list with Similar Creators or AI Search first, then call this endpoint for the ones that return null emails. Names the alternatives and the condition that selects this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
