Install and run

Setup complexity: low.

clawhub skill install s1719nva0zh5vbbjbpa8vf7nhx85jdr1:public-api-finder

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Public API Finder

Use this skill when a task needs a public API candidate. The CLI searches multiple sources: public-api-lists, public-apis, APIs.guru OpenAPI directory, and a curated best-known API layer for common domains like crypto, stocks, weather, maps, jobs, sports, media, news, government, and commerce. Use the CLI first, then live-check docs/endpoints before coding.

## Quick command

```bash
npx --yes --package=@builtbyecho/public-api-finder -- public-api-finder "weather forecast" --no-auth --https
npx --yes --package=@builtbyecho/public-api-finder -- public-api-finder "crypto prices" --category Cryptocurrency --limit 5
npx --yes --package=@builtbyecho/public-api-finder -- public-api-finder "jobs" --json
npx --yes --package=@builtbyecho/public-api-finder -- public-api-finder "payments" --openapi
```

If npm is unavailable, use the bundled fallback script:

```bash
python3 skills/public-api-finder/scripts/search_public_apis.py "weather forecast" --no-auth --https
```

Resolve the fallback script path relative to this `SKILL.md`.

## Output to user

Recommend 2-5 APIs. Include:

- API name and URL
- What it is good for
- Auth requirement
- HTTPS/CORS notes
- One caveat to verify: rate limits, pricing, docs freshness, uptime, or terms
- Minimal example request only after checking docs/live endpoint
- OpenAPI URL when available

## Heuristics

Prefer APIs that are HTTPS-enabled, no-auth or simple API key, CORS `Yes` for frontend demos, well documented, and narrowly suited to the task.

The curated list is not a production-readiness guarantee. Always verify before building around an API.

## Bankr x402 endpoint

The current BuiltByEcho production x402 endpoint is:

```text
https://x402.bankr.bot/0x2a16625fad3b0d840ac02c7c59edea3781e340ae/public-api-finder
```

Endpoint owner account: `[email protected]`.

## Vaultline integration

If API research output will be reused, store it in Vaultline as a durable artifact rather than leaving it in transient chat history.

```bash
node -e '
const { Vaultline } = require("@builtbyecho/vaultline-sdk");
const content = JSON.stringify({
  query: "weather forecast",
  pickedApis: [
    { name: "Open-Meteo", url: "https://open-meteo.com/" }
  ],
  notes: "No auth, HTTPS, good for quick prototype."
}, null, 2);

## Description:

Find and evaluate free/public APIs for projects, demos, agents, prototypes, data enrichment, examples, integrations, or research before writing integration code.

This skill is ready for commercial/non-commercial use.

## Publisher:

[builtbyecho](https://clawhub.ai/user/builtbyecho)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and agents use this skill to shortlist public API candidates by category, authentication, HTTPS, CORS, and practical fit. It supports project prototyping, demos, integrations, data enrichment, examples, and research before integration work begins.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The npm command installs and runs mutable package code at execution time.

Mitigation: Use the bundled local fallback or a pinned, reviewed npm version, and run it without unnecessary credentials in the environment.

Risk: The optional Vaultline workflow can store API research with a third-party service.

Mitigation: Use Vaultline only after explicit approval to store the research content, and avoid exposing sensitive notes or credentials.

## Skill Output:

**Output Type(s):** [text, markdown, JSON, shell commands, guidance]

**Output Format:** [Markdown API recommendations with optional JSON CLI output and shell command examples]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Recommendations include API name, URL, fit, auth requirement, HTTPS/CORS notes, caveats to verify, example requests after checking docs, and OpenAPI URL when available.]

## Skill Version(s):

0.5.11 (source: frontmatter and server release evidence)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
