Batch Validate IBANs

batch_validate_iban

Read-onlyIdempotent

Validate up to 100 IBANs in a single call at $0.002 per IBAN (60% cheaper than calling validate_iban repeatedly at $0.005). USE WHEN: the user pastes a list of IBANs, asks to clean a CSV/spreadsheet of bank accounts, asks to dedupe a customer database, asks to triage a payout list before sending, or whenever you would otherwise call validate_iban more than 2-3 times in a row. RETURNS: { results: [...same shape as validate_iban], count, valid_count }. COST: $0.002 per IBAN (free: 10 units/IP/day on this transport, one per call and one per IBAN in batch_validate_iban, or a free API key at POST https://api.ibanforge.com/v1/keys/generate for 200 REST calls/month).

A4.4/5.0

Behavior4/5

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

Annotations already mark the operation as read-only, idempotent, and non-destructive. The description adds valuable behavioral context beyond that: detailed cost per IBAN, free tier limits, the exact return shape ({ results, count, valid_count }), and a note that results match validate_iban's shape. No contradictions with annotations.

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

Conciseness4/5

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

The description is longer than average but well-structured with clear 'USE WHEN', 'RETURNS', and 'COST' sections. Every sentence contributes either usage guidance, return details, or pricing. The cost explanation is a bit detailed but relevant for decision-making. It is efficient despite the length.

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?

Combined with the output schema and annotations, the description provides everything needed to call the tool correctly: purpose, batch limit, trigger conditions, return shape, and cost considerations. There are no missing pieces that would cause an agent to misuse it.

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?

The input schema already fully describes the 'ibans' parameter as an array of 1-100 strings (100% coverage). The description repeats the 'up to 100' limit but does not add format, examples, or edge-case guidance beyond what the schema provides. This meets the baseline of 3 for high schema coverage.

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?

The description states a specific verb ('Validate'), a resource ('IBANs'), and a clear batch constraint ('up to 100 IBANs in a single call'). It also distinguishes itself from the sibling validate_iban by highlighting the batch nature and cost advantage, so an agent can immediately tell it apart.

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?

Provides explicit 'USE WHEN' scenarios: pasting a list, cleaning a CSV/spreadsheet, deduping a customer database, triaging a payout list. It also gives a concrete decision rule: use instead of validate_iban when calling it more than 2-3 times in a row, and notes the cost difference. This fully covers when-to-use and alternatives.

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

A4.5/5.0

Disambiguation4/5

Each tool has a distinct job, and the descriptions provide strong USE WHEN/DO NOT USE cues. The only plausible boundary cases are validate_iban vs batch_validate_iban (single vs bulk) and validate_iban vs check_compliance (general enrichment vs payment-risk triage), but both are clearly signposted.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern: validate_iban, check_compliance, lookup_bic, send_feedback, etc. batch_validate_iban reads as a compound verb + object and does not break the convention, and the verb choice also aligns with intent: validate for format checks, check for rule/risk checks, lookup for directory data.

Tool Count5/5

Eight tools are well-scoped for an IBAN validation and payment-intelligence API: single/batch validation, compliance, address rules, reference validation, BIC and Swiss clearing lookups, and feedback. Each tool carries a distinct capability and none feels redundant or padding.

Completeness5/5

The surface covers the full IBAN-informed workflow: validation, enrichment, batch processing, BIC/Swiss clearing resolution, payment-reference pairing, postal-address rail rules, and pre-payment compliance triage. Explicit limitations such as not verifying account existence or payee identity are domain constraints, not missing tools.
